Please give a detailed response! Thank You!

FLOW OF GENETIC INFORMATION - TRANSCRIPTION & TRANSLATION

1. Describe/Explain the degeneracy of the genetic code. How does degeneracy impact the flow of genetic information?

2. Explain which of the following characteristics of DNA-dependent DNA synthesis (i.e. replication) is NOT the for DNA-dependent RNA synthesis?

(a) synthesis requires a template (b) requires a primer

(c) imitation involves recognition of DNA (d) synthesis is 5’ to 3’

3. Explain the stage of translation when an incoming tRNA has bound to the A-site on the ribosome. Describe/Explain the addition of amino acids to the growing polypeptide chain.
