Why is gc content in different genome different?

Hi, biostars!

Why is gc content in different genome different? For example, gc content in genome A is 52%, meanwhile gc content in genome B is 49%. Why gc content is related to species? Is there any biological explanation?

Thanks

Hello thustar!

We believe that this post does not fit the main topic of this site.

Biostars is for informatics and analysis questions. You have asked a pure biology question we are not qualified to answer. The GC content varies because all content varies between genomes.

For this reason we have closed your question. This allows us to keep the site focused on the topics that the community can help with.

If you disagree please tell us why in a reply below, we'll be happy to talk about it.

Cheers!

N.B., I wouldn't say we're not qualified to answer (many of us are biologists), rather that such questions are just off-topic here and the biology stackexchange site is more appropriate.

It may be due to the fact that the head including its internal structures appear to contain more curves (I'm thinking of the brain and skull) than the rest of the body. Just a guess. This also includes the individual hair strands which even if straight are in reality - like all straight lines - just.. well... curves!
