Which of the following point mutations is likely to be the worst for an organism if they happened in the second codon of a gene coding for an essential protein?
A) missense
B) silent
C) nonsense
Identify the single most correct answer:
a) Ribosome is an organelle found in both prokaryotes and eukaryotes.
Ob) During conjugation a naked DNA molecule found in the surroundings gets
into bacteria.
c) Spontaneous mutation cannot result in the production of an altered protein.

a) The promoter specifies how efficient a mRNA binds to the ribosomes.
Ob) An amino acid is represented by one and only one codon.
Oc) Ribozymes are RNA molecules with enzymatic activities.
d) Each tRNA contains a unique codon.
