Gene Rearrangement and Evolution

Clear this up for me: To say genes rearrange in a cell is to say a person's DNA changes. True or false? Also, can someone give me some info on "jumping genes"? I've been trying to decide if they really are a factor in evolution. I want to make sure I have this straight: Certain genes calle...

Re: Microbiology, Biological Sciences, (x)

Thank you very much for the help. However, there is one thing in particular that I am concerned about, and that is that I didn't have a good chemistry teacher, so I practically have no base in the subject. I looked a little more into your suggestions and they all seem interesting. At one of the coll...

Okay, so I'm only working on what high school knowledge I have, but... 1) cells divide because they either are getting to big and that puts a strain on their genetic material and because the surface to volume ratio of the cell makes it difficult to transport material in and out of the cell. So I gue...

Microbiology, Biological Sciences, (x)

I'm having trouble with deciding what choice of major I should pursue. I've narrowed my choices to those above (but willing to research others, hence the (x)) and am simply at a loss as to which one will best lead me to an ideal career (which may also change). Currently I'm interested in a career th...

Need help understanding chromosomes

Okay, I'll say what I know or what I think I know. Do tell me if I say something wrong. So chromosomes are condensed pieces of DNA, right? And chromosomes have a number of genes. And chromosomes from mom and dad have the same genes, but have different alleles. Do chromosomes control a number of trai...
