After going through the bio section destroyer, I have a few questions I would like more clarification on.
1) A protein of 210 amino acids is made from how many DNA nucleotides?
I understand that the answer is 210 x 3=630 but in the answer key is says that 3 codons make one amino acid. I'm not sure if this is a typo or my misunderstanding but I thought that 3 nucleotides make 1 codon, therefore 1 amino acid. So that 210 amino acids is made from 210 codons and 630 nucleotides. Is this correct?
2) What is the difference between natural killer T cells and cytotoxic killer T cells (if any)?
3) I don't understand the relationship between linked genes, recombinant genes and crossing over. I believe that the closer two genes are on a chromosome, the greater chance they will be linked, and the farther they are the more likely there will be recombination. Also know that crossing over makes recombinant dna. Any more information about these topics and the sort of questions that might be tested would be great.
