protein synthesis re-test

Front

What is a codon?

Back

A codon is a three-nucleotide sequence in mRNA that codes for a specific amino acid.

Front

What mutation occurs when one nucleotide is replaced by another?

Back

Substitution.

Front

What are the possible effects of mutations?

Back

Mutations can be harmful, neutral, or beneficial.

Front

Are mutations random?

Back

Yes, mutations occur randomly.

Front

What role does tRNA play in protein synthesis?

Back

tRNA transports amino acids to the ribosome during protein synthesis.

Front

What is the function of mRNA?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the role of rRNA in protein synthesis?

Back

rRNA is a component of ribosomes and helps facilitate the translation of mRNA into proteins.

Front

Define mutation.

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.

Front

What is the difference between insertion and deletion mutations?

Back

Insertion mutations add one or more nucleotides, while deletion mutations remove one or more nucleotides from the DNA sequence.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are added or deleted, altering the reading frame of the genetic code.
