Also, random mutations always happen, but are not expressed. That would be like saying that a random mutation in you right now can give you feathers and make you fly. We know that's not the case. Not to mention, we know you can remove the nucleus of the cell, where all the reproductive genes are stored, and the cell keeps working exactly the same as before. If the nucleus is there or not, doesn't matter. Same is for the genes in the nucleus. It's only used for reproduction and are expressed afterwards.
But honestly, don't you think it's funny what the article is saying? Cells are under stress, so, chance for mutations increase, but because of the "burden" of reproduction only the right one is selected and expressed, giving the "illusion" of a selected mutation.. I mean.. Seriously? I don't know.. Maybe if it looks like bird, flies like a bird, sounds like a bird, it is a bird? Just a thought...
The whole argument is under the assumption that everything happens in a randomly materialistic way. You can view the same evidence and data the other way, which is, the selection is directed, and whole stress/mutation-increase/burden/selection/expression thing, is the mechanism by which this choice is expressed.. But of course, you're not allowed to look at it that way...

I doubt you truly with all your heart believe in evolution.
You seem to have some type of sense. Same goes to the big athiest. It's just easier for u to say that there is no God to accept the misery in your lives.
Try your hardest to find faith and truth I assure you not only will science/history tie into the biblw perfectly but you will have a peace of mind that no monkey to human theory could ever prove.
But then again evolution has never been proved just like I can't prove that God exist. It's similar to the argument that aliens exist because we can't prove they don't and vice versa.
A rather pointless arguement, we all seem to have our minds set, but in the end you will feel embarrassed for believing something as great as a human came from a stinking animal.

We have also monitored the behavior of cells after enucleation, trypsinization, and replating. The results in this report demonstrate that the information necessary for normal cell-shape formation, cell locomotion, and contact inhibition is present in enucleated cells and is preserved through trypsinization and replating. Preliminary results of this work have been reported elsewhere.
The cytoplasts, on the other hand, for a period of 24 hr display most of the behavioral characteristics of intact nucleated cells.
Reassembly of microtubular and microfilament structures associated with cell attachment, spreading, and shape formation from preexisting subunit pools is thought to occur in recovered cytochalasin Benucleated cells (5), which appear to retain many of the cell membrane-dependent functions that may be essential to rickettsial penetration.
--------------------------------------------
rickettsial multiplication appears to continue in a few surviving enucleated cells after many hours.
--------------------------------------------
Similarly, another nuclear function, i.e., host cell ribosomal ribonucleic acid synthesis (5), would not appear to be essential for growth of R. prowazeki.

I knew you would say something like that.

It's just like logically refuting a religious belief and then hearing "the bible tells us blah blah so that's the truth". So blind..., it's not even funny. The sad thing is, you yourself don't see it..

The cell can live fine without the nucleus, and I have posted tons of articles showing that. But, whatever... You are right and I'm wrong, like always...
Lol.. Uhuh.. Lemme guess, you trust all that your school books tell you, and those are definitely always right.

Taken out of context..? Really..? Fine.. Whatever suits you.. And this is nothing more than another religious argument. "You took my bible out of context to enforce your opinion".

You, on the other hand are very biased. You've decided that it's what it's and pick sentences out of context to support your uneducated opinion.
You are the one taking it out of context. You are the one taking what the general report is all about, and applying it to that sentence. The sentence clearly states, that the cells maintain the information necessary for locomotion, which is the movement of the cell, meaning, it certainly is against your statement of them "not even living anymore". And that's only one of the three they mentioned...

All this is related to tubulin. It was already established in the previous article that tubulin mRNA might not degrade quite as quickly as typical mRNA. This does not confirm what you said: "cells function just like before". It merely states that this one particular function is not dependant on fresh mRNA (certainly not the case for vast majority of functions).
That's irrelevant. It alters the DNA, resulting in faulty cellular reproduction. Also, I think, you're not really aware of what I mean. When I talk about a cell working just fine, I'm talking about a single individual cell. Of course the community of cells dies out if they can't reproduce. If they would remove the balls from all men so none of them could reproduce, humanity will die out too. It does not mean, that you as an individual, will die immediately without them. You can survive without them and perform everything fine without them, provided they don't leave you bleeding to death. Same for a cell and its nucleus.

Oh and if you really think that cells do just fine without DNA then how about you dip your hand into Ethidium Bromide for say 5 minutes?
If they remove your brain, how long do you survive? Exactly, you die instantly. The nucleus is not the brain and cells can survive fine without the nucleus. If they couldn't, they would die instantly. They lose their capability to reproduce, and to make proteins. All the other function are perfectly intact, and they are still functional. Like, locomotion, stated above.. Is that so hard to understand? Of course they die after an EXTENDED period of time, not able to replenish themselves.. They don't die immediately..

This article clearly states: Enucleated cells have without exception failed to survive for an extended period,.. How is failure to survive in any way normal?
Genetic determinism? If that's not true, the current evolutionary model is not true. This does not mean evolution does not happen, it just happens in a different way..

Whats your point with the enucleated cells, how is it relevant to the topic?
No they don't. Genes have the instructions to produce proteins. They are not functional until there's a signal from the environment. Genes can't activate or deactivate themselves, so in that sense, they already lose the capability of controlling anything, if they can't even control themselves. It's the perception of the environment by the cell that activates genes. There's a reason there's something we call epigenetics.

Genes control proteins, which IS life.
Lol.. You're stating exactly the same as I've been stating the whole time.. Like I said on the last page...:

Are you familiar with transcription and translation processes? Thats the way how cell replenishes its proteins. If the nucleus is removed, no new RNA transcripts for ribosomes are being created, thus protein synthesis becomes inhibited, and degraded proteins are not replenished, and cells slowly die. Not even talking about the regulatory function of genes, for example facilitating adaptive responses, and not just replenishing proteins that are always present. It may take a relatively long time for the cell to die, depending on the protein degradation half-life, but to say that the enucleated cells can work "exactly as before", or "it doesnt matter if the nucleus is there", or "genes are used only for reproduction", that is simply false.

The only difference is that they can't reproduce and they can't manufacture protein. Lots of people believe the cells die because they lack the nucleus, but they stay alive without it. They just die over time because they can't replenish proteins that are worn out without the nucleus, but they are very much alive and functional without it.

Imagine for a second that they remove all the nuclei from all the cells from your body. Do you die as a direct cause of it? Of course you don't. You die overtime because your body can't replenish itself anymore. The nuclei is an indirect cause, not THE cause. The real cause is the wearing down of your body parts. You do not lose any function directly when you lack nuclei once your body is fully formed.
And another funny thing, by saying that cells can't survive without a nucleus you are leaning towards intelligent design, with the "irreducibly complex" stuff, because that would mean that if the cell lacks one component, it will lose all function. Obviously, that's not the case. You're not an intelligent design supporter are you..?

Nygdan please, evolution is not a fact, it's a theory.
Proven facts (premises):
1. mutations in the DNA happen e. g. each offspring is slightly different from the parent (mutations supplement variation (changes) to population)
2. natural selection promotes positive changes and supresses negative changes in a population, according to environment
3. if two populations of the same species became separated by some reproductive barrier (rivers, mountains..), there is NO mechanism to synchronize these inevitable changes in both populations, so over time they will inevitably diverge to the point that they wont be able to interbreed anymore - speciation
This three FACTS alone are enough to deduce that evolution happens. And proof by deduction is also a valid way to obtain scientific knowledge. So even if we didnt have paleontology, developmental biology etc., just biochemistry (the 1st point) and population genetics (2nd and third points) is enough to prove evolution, even macroevolution - speciation.
