PS & Mutations

Front

What is the role of mRNA?

Back

mRNA provides information to make proteins.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can affect how genes function.

Front

What are the three types of mutations?

Back

Insertion, deletion, and substitution.

Front

What is gene expression?

Back

Gene expression is the process by which information from a gene is used to synthesize a functional gene product, usually a protein.

Front

What is a substitution mutation?

Back

A substitution mutation is when 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 base pairs are added into a DNA sequence.

Front

What is a deletion mutation?

Back

A deletion mutation occurs when one or more nucleotide base pairs are removed from a DNA sequence.

Front

How can mutations affect proteins?

Back

Mutations can change the amino acid sequence of a protein, potentially altering its function.

Front

What is the significance of the triplet code in DNA?

Back

The triplet code in DNA specifies the sequence of amino acids in a protein.

Front

What is the impact of temperature on gene expression in arctic foxes?

Back

Temperature regulates gene expression for fur color in arctic foxes, causing seasonal changes.
