1. Why is DNA replicated prior to mitosis?



2. Can you think of a reason why human gametes have only 23 chromosomes, one of each pair?





3. Chimpanzees have 48 chromosomes in their somatic cells. How many chromosomes do you

think are found in their sex cells?



4a. What amino acid would be produced if transcription took place from the DNA sequence

CAT? For each scenario, be sure to show the products (mRNA codon, tRNA anticodon, and

amino acid) for each step of the process. (1 point each)

mRNA codon: __________________________

tRNA anticodon: __________________________

amino acid: __________________________



4b. If a genetic mistake (i.e., a mutation) occurred during replication and the new DNA strand

has the sequence CAG, what amino acid would result?

mRNA codon: __________________________

tRNA anticodon: __________________________

amino acid: __________________________



4c. What if the mutation resulted in a DNA strand with the sequence GAT?

mRNA codon: __________________________

tRNA anticodon: __________________________

amino acid: __________________________DNA.......................?
These are all pretty easy and basic questions. You should be able to answer them if you open your book. If you don't have the book, all of the information is easily found on the web.DNA.......................?
I think I am taking the same course that you took 9 months ago, did you ever find these answers? Any help would be greatly appreciated. Thanks!
