I thought it was a framshift mutation due to the deletion. But I dont know, I got all confused because what if these two genes are coming from two seperate individuals, coding for a heterozygous. Then wouldn't the molecule be functional? Mutations to a hemoglobin are recessive?? Im so confused, and ...

There was a depurination right? The structure determines function, frameshift alteration would alter function?

protein sequence

I got this question tomorrow on my final. I believe I have worked out the answer, but I would appreciate some clarification. There are two DNA sequences listed below which correspond to the sequence of the gene that codes for the protein hemoglobin. One sequence is a normal DNA sequence (i.e., wild ...

Membrane Interior

Is there fluid (water) within the hydrophobic interior? Im having a little trouble understanding my text book. If the tails of the phospholipids are hydrophobic then there should be water within the chains. But then I read that the phospholipid bilayer is fluid. Why? Im not sure but is it because of...

Entering/Leaving the Nucleus

Im almost 98% sure it's the nuclear pores that controls what enters and leaves the nucleus. The nuclear pores are embedded within the nuclear envelope and they allow molecules to diffuse freely between the nucleoplasm and the cytoplasm and they control the passage of proteins and RNA-protein complex...

Your right that was a very general question. To be more specific, I have a couple of examples here in my book that I just dont understand. Maybe I'll start with one. Living systems alter their environments, the most obvious change is that living systems are selective in the isotopes of carbon in com...

I searched my text book, net and forum after forum for info on the first cells. According to my text Prokaryotes were the first forms of li...

Tell you what: ignore what biologists say and do. Instead of using antibiotics, medicinal drugs, specialist crop varieties etc, why don't you just pray? Pray to your god for food and medicine. I sense sarcasim Minuteman or maybe I just hope your being sarcastic. This seems like a pretty elementary ...
