Unit 8 & 9 TEST CORRECTIONS

Front

What is asbestos and its link to cancer?

Back

Asbestos is a building material that has been linked to certain types of cancers due to its ability to cause mutations in the p53 gene, which controls tumor suppression.

Front

What is the difference between somatic cell mutations and gamete mutations?

Back

Somatic cell mutations are generally not passed to offspring, while gamete mutations are usually passed to offspring.

Front

Where is the genetic code primarily located in humans?

Back

The genetic code is primarily located in the nucleotides of DNA.

Front

What causes genetic variation in gametes?

Back

Genetic variation in gametes is caused by independent assortment during meiosis.

Front

What is a somatic cell?

Back

A somatic cell is any cell in the body that is not a sperm or egg cell.

Front

What is a gamete?

Back

A gamete is a reproductive cell (sperm or egg) that carries half the genetic information of an organism.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in traits or functions.

Front

What is the role of the p53 gene?

Back

The p53 gene is a tumor suppressor gene that helps regulate the cell cycle and prevent cancer.

Front

What is independent assortment?

Back

Independent assortment is the process during meiosis where chromosomes are distributed randomly into gametes, leading to genetic variation.

Front

What is an insertion mutation?

Back

An insertion mutation is a type of mutation where extra base pairs are added into the DNA sequence.
