Front

What are mutations?

Back

Mutations are changes in the DNA sequence that can lead to genetic variation within a population.

Front

Why are mutations important?

Back

Mutations are important because they bring about genetic variation needed for a population to evolve.

Front

What is the role of DNA Polymerase?

Back

DNA Polymerase is the enzyme responsible for adding nucleotides during DNA replication.

Front

What is transpiration in plants?

Back

Transpiration is the process where water evaporates directly from the leaves of plants.

Front

What defines a species?

Back

A species is defined as organisms that can interbreed and produce fertile offspring.

Front

What is a sex-linked recessive disease?

Back

A sex-linked recessive disease is a genetic condition that is associated with genes located on the sex chromosomes.

Front

What percentage of offspring will inherit a sex-linked recessive disease from a carrier mother and a normal father?

Back

25% of the offspring will inherit the sex-linked recessive disease.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a population.

Front

What is the function of topoisomerase?

Back

Topoisomerase is an enzyme that helps relieve the strain of unwinding DNA during replication.

Front

What is the function of ligase in DNA replication?

Back

Ligase is an enzyme that joins together Okazaki fragments on the lagging strand during DNA replication.
