Mutations and Protein Synthesis

Front

What is a frameshift mutation?

Back

A frameshift mutation is a genetic mutation caused by the insertion or deletion of nucleotides in a DNA sequence, which alters the reading frame of the genetic code.

Front

What type of mutation occurs when a nucleotide base is added to the DNA sequence?

Back

Insertion Mutation

Front

Where does transcription occur in eukaryotic cells?

Back

Nucleus

Front

What best describes the structure of a DNA molecule?

Back

Double helix.

Front

Why is DNA important for living organisms?

Back

It serves as the blueprint for traits of all living things.

Front

What is the flow of genetic information in cells?

Back

DNA -> RNA -> Protein.

Front

What is a deletion mutation?

Back

A deletion mutation is a type of mutation where one or more nucleotide bases are removed from the DNA sequence.

Front

What is a substitution mutation?

Back

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

Front

What role do ribosomes play in protein synthesis?

Back

Ribosomes are the cellular structures where proteins are synthesized by translating mRNA.

Front

What is the function of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosomes for protein synthesis.
