Question

5.) TRUE/FALSE (1 point for each correct answer): DNA Replication: Several proteins collaborate with DNA polymerase to replicate DNA: a.) Helicase separates double stranded DNA into two single strands b.) Clamp Loader loads the DNA polymerase onto the DNA c.) Primase generates a RNA primer required by the DNA polymerase to initiate DNA polymerization d.) Ligase connects Tonegawa fragments on the Leading strand Protein Translation: Several proteins collaborate with the ribosome to translate mRNA into protein: a.) EF-Tu enforces proper Codon/Anticodon pairing b.) EF-G catalyzes the peptidyl-transfer reaction c.) 64 distinct Aminoacyl-tRNA synthetases charge tRNAs with the Aminoacids specific to their anticodons d.) Several steps in Translation require a GTP/GDP switch

Explanation / Answer

DNA replication

a, b, c are correct

d is false. Ligase connects okazaki fragments on lagging strand.

Protein synthesis

a, b are correct

c is false. Only 20 aminoacyl trba synthetases are present.

d is false. Only third step of translation requires gtp gdp switch.
