"new DNA is needed to code all the new parts of a larger organism when you start with something simple."

Yeah, I already explained that. Reading=good.

[dt28469]

@supowit Calm the fuck down dude! Seriously! The point im trying to make is that when simple life began, it oviously didnt have a large genome. But to get larger creatures, you need to expand it. You know, new DNA is needed to code all the new parts of a larger organism when you start with something simple. Thats all im trying to say.

Sigh. Mammoths: 4.7 billion bp. Largest mammal genome ever. But not the largest mammal ever.

Wheat: 16 billion bp.

And my favorite... the one that blows your ignorance to kingdom-fucking-come: Amoeba - 670 billion bp.

I could go on. Do a little research before you fuck with people who have degrees in molecular biology.

@supowit What are you talking about? Yeah it does! A single cell organism doesnt require alot of information to build itself. Most dont even have chromosomes. An animal like a human has over 200 different types of cells in their body. Thats alot more genes to code all these cell types. And that doesnt include the genetic switches and timers that triggers them.

E-coli genome: 4 Million base pairs

C. elegans genome(1mm worm): 97 Million base pairs

Human genome: 3 Billion base pairs

@dt28469

Furthermore, a greater number of basepairs or chromosomes does NOT correspond to "bigger" organisms.

@dt28469

Adding information does not REQUIRE the genome to get bigger. A simple mutation of an existing gene is by definition added information, if the new protein has a viable function.

But I know what you were thinking. More base-pairs = more genes, and we still don't know how new DNA gets added to a genome..

Except we do know how that works. The three prime candidates for mutagenesis of this form are retroviral insertion, translocation, and gene duplication.

[dt28469]

@supowit What are you saying? that added basepair sequences come from errors in the duplication of genes or that you cant add new base pairs? The whole no added info is basically that you need a bigger genome to make bigger lifeforms. but how does a genome get bigger? 

[supowit]

@dt28469

added information is not the same as added basepair sequences. That particular magic is done by gene duplication, chromosome fusion, or retroviral insertion.

Got I love molecular biology. Now get outa my house.

[dt28469]

Thats not the addition of information, thats the changing of information that already exists.

ex.

genome 1 (original) = atgctta

genome 2 (added info) = atgcattagtcctta

genome 3 (what ur saying) = atgatta

Thats an example of added info. As you can see, the sequence attagtcc in the middle of genome 2 was ADDED. genome 3 has no additions, rather it has CHANGES. only changes have been observed in nature. No additions

Ps. im not a creationist
