5.4 Study Guide

Question 1

What is a codon?

Answer 1

A pairing of 3 RNA nucleotides that code for one amino acid.

Question 2

What is an anticodon?

Answer 2

3 bases on the tRNA that will code with the mRNA codon.

Question 3

What is the role of mRNA in translation?

Answer 3

Contain message/code for amino acid sequence.

Question 4

What is the role of tRNA in translation?

Answer 4

Transfers amino acids, contains anticodons that pair with mRNA codons to put amino acids in the correct order.

Question 5

What is the role of rRNA in translation?

Answer 5

Facilitates matching of mRNA and tRNA, and joins amino acids to synthesize protein.

Question 6

What is the term for a pairing of 3 RNA nucleotides that code for one amino acid?

Answer 6

Codon.

Question 7

What is the term for 3 bases on the tRNA that will code with the mRNA codon?

Answer 7

Anticodon.

Question 8

What is translation?

Answer 8

Making a protein using the codons on mRNA as instructions.

Question 9

What are the types of mutations?

Answer 9

Point mutations, silent mutation, missense, nonsense, frameshift (insertions and deletions).

Question 10

What is the term for making a protein using the codon on mRNA as instructions?

Answer 10

Translation.

Question 11

Please explain the mutations.
