Mutation Practice Questions 2

Front

What is the influence of genetic variation and environmental factors on gene expression?

Back

Genetic variation and environmental factors can significantly affect how genes are expressed, impacting human health and disease.

Front

What is gene expression?

Back

Gene expression is the process by which genes are activated or deactivated by environmental experiences throughout development.

Front

What are proteins made of?

Back

Proteins are made of amino acids that are joined together in a specific order.

Front

What type of chromosomal mutation involves removing genes and re-attaching them backwards?

Back

Inversion is a type of chromosomal mutation that removes genes and then re-attaches them in reverse order.

Front

What carries genetic information from the nucleus to the ribosome?

Back

mRNA (messenger RNA) carries a copy of the genetic information from the nucleus to the ribosome.

Front

Define mutation.

Back

A mutation is a change in the DNA sequence that can lead to changes in gene function or expression.

Front

What is the role of ribosomes in protein synthesis?

Back

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

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and stores genetic information, while RNA is single-stranded and plays a role in protein synthesis.

Front

What is a chromosomal deletion?

Back

A chromosomal deletion is a mutation where a segment of DNA is removed, leading to the loss of genes.

Front

What is translocation in genetics?

Back

Translocation is a chromosomal mutation where a segment of DNA is moved from one location to another, potentially disrupting gene function.
