Accepted Answer

nucleus

Answer

cell

Answer

nucleotide

Question 10

Which anticodon would be placed in spot #2

Accepted Answer

GGA

Answer

GGC

Answer

CCA

Answer

GGT

Question 11

Which process does this diagram illustrate?

Accepted Answer

translation

Answer

transcription

Answer

DNA replication

Question 12

How can a mutation in the DNA sequence result in NO change to the protein that is made?

Accepted Answer

There are multiple codons that can code for the same amino acid and result in the same protein

Answer

There is always a change in the protein when a mutation occurs

Answer

Only the mRNA is used in protein synthesis so a mutation in the DNA would have no effect on the protein

Question 13

What is the role of mRNA in protein synthesis?

Accepted Answer

It carries the genetic code from DNA to the ribosome.

Answer

It forms the structure of the ribosome.

Answer

It transports amino acids to the ribosome.

Answer

It catalyzes the formation of peptide bonds.

Question 14

Which of the following processes occurs in the ribosome during protein synthesis?

Accepted Answer

Translation

Answer

Transcription

Answer

Replication

Answer

Mutation

Question 15

What is the significance of the start codon AUG in protein synthesis?

Accepted Answer

It codes for the amino acid methionine and initiates translation.

Answer

It signals the start of DNA replication.

Answer

It terminates the process of transcription.

Answer

It is involved in the splicing of introns.
