Question
1)
Telomeres are repetitive sequences at the end of each chromosome required:
to allow for filling of the 3’ overhang at the end of a newly synthesized strand of DNA
to facilitate in DNA repair due to mutagenesis
to function as primers for DNA synthesis on the lagging strand
for initiation DNA replication in the 3’ to 5’ direction
2)
Which of the following polymerases is responsible for removing RNA primers during DNA replication?
RNA polymerase
RNaseH or Pol I
DNA Pol or Pol III
DNA Pol II
3)
For any given mRNA there are 3 reading frames. The reading frame is determined by the the presensce of which of the following:
an in frame start codon (AUG)
transcriptional initiation site
Slice sites
termination codon
4)
The genetic code is said to be degenerate because of which of the following?
Many codons have pairs of identical bases next to each other.
All triplets have at least one uracil.
Many of the amino acids have more than one triplet codon
Some triplets are made up of repeating purines or pyrimidines.
