I think what green dog is trying to hint at, is that there are of 64 triplets of nucleotides (codons) in the human genome. with 3 exceptions, each codon encodes for one of only 20 amino acids which synthesize of proteins. that means there is redundancy. most of the amino acids are being encoded by m...

When it is shown that shown genetically that two (or more) genes control a phenotype, the genes are said to ...

They only have one DNA molecule, so what happens is that DNA molecule is replicated (copied), then cell walls form around each of ...

I am not sure i understand your questions. Are you a sking why is it if telomerase is not in the cell, can you get diseases (which are caused by the shortening of telomeres?)

here are a few sites and articles that you may find helpful, especially if you are doing a seminar:
