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.

If the bold term in each statement is correct hen write the letter C next to it. if the term is incorrect then replace it with the correct term.

The nucleotide bases found only in RNA and not in DNA is thymine.

The class of RNA molecules that carries the amino acids that are added to the growing polypeptide chain is tRNA.

During translation immediately after the first and second tRNA molecules become attached side by side on the mRNA., a hydrogen bond is formed between adjacent amino acids.

In the genetic code, 20 bases on the DNA code for a single amino acid.

The major lipid involved is transcription is RNA polymerase.

The one strand of DNA used as a template in the making of mRNA during transcription, is the template strand.
