question 9
the genetic code is degenerate because there are only 20 amino acids but 64 codons
true
false
question 10
rna polymerase needs a dna primer to initiate transcription
true
false

Explanation:

QUESTION 9

The genetic code is degenerate because multiple codons can code for the same amino acid. Since there are 20 amino acids and 64 possible codons (3 - nucleotide combinations, \(4^3 = 64\)), most amino acids are encoded by more than one codon, which defines the degeneracy of the genetic code. So the statement is True.

RNA polymerase initiates transcription without a DNA primer. DNA polymerase (in DNA replication) requires a primer, but RNA polymerase can bind to the promoter region of DNA and start synthesizing RNA directly. So the statement is False.

Answer:

True
