Protein Synthesis and Mutations Review

Front

What is protein synthesis?

Back

Protein synthesis is the process by which cells generate new proteins, involving transcription of DNA to mRNA and translation of mRNA to amino acids.

Front

What are the two main stages of protein synthesis?

Back

The two main stages of protein synthesis are transcription and translation.

Front

What is transcription in protein synthesis?

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes read mRNA sequences to synthesize proteins.

Front

What is a mutation?

Back

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

Front

What are the types of mutations?

Back

The main types of mutations are substitution, insertion, deletion, and frame-shift mutations.

Front

What is a substitution mutation?

Back

A substitution mutation is a type of mutation where one base pair in the DNA sequence is replaced by another.

Front

What is an insertion mutation?

Back

An insertion mutation occurs when one or more nucleotide bases are added to the DNA sequence.

Front

What is a deletion mutation?

Back

A deletion mutation happens when one or more nucleotide bases are removed from the DNA sequence.

Front

What is a frame-shift mutation?

Back

A frame-shift mutation is caused by insertions or deletions that change the reading frame of the genetic code.
