what does it mean when we say the genetic code is \degenerate?\
○ it behaves badly, and acts as a parasitic entity
○ a given amino acid can be coded or \called\ by no more than one nucleotide codon triplet
○ a given amino acid can be coded or \called\ by more than one nucleotide codon triplet

which enzyme is responsible for putting together new dna segments produced on the lagging strand during dna replication?
○ dna polymerase
○ dna ligase
○ rna primase

Explanation:

Question 5

The genetic code being "degenerate" refers to the property where a single amino acid can be encoded by multiple (more than one) nucleotide codon triplets. The first option is incorrect as it misinterprets "degenerate" in a non - biological context. The second option is wrong because it states the opposite of what degeneracy means (it says no more than one, but degeneracy is about more than one).

• DNA polymerase is mainly responsible for adding nucleotides to the growing DNA strand, not for joining the Okazaki fragments (the new DNA segments on the lagging strand).
• DNA ligase has the function of joining the Okazaki fragments together on the lagging strand during DNA replication.
• RNA primase is responsible for synthesizing the RNA primer which is used to start DNA synthesis, not for joining DNA segments.

Answer:

C. a given amino acid can be coded or "called" by more than one nucleotide codon triplet
