What is a harmful mutation?

Back

A mutation that negatively affects an organism's ability to survive or reproduce.

Front

What is cancer in relation to cell growth?

Back

Cancer is a condition where body cells grow uncontrollably.

Front

If a DNA molecule consists of 29% Guanine, how much Cytosine will it contain?

Back

29% Cytosine, due to base pairing rules (A=T and G=C).

Front

What are nucleic acids made of?

Back

Nucleic acids are made of sugar, phosphate, and nitrogen bases.

Front

What are the four nitrogen bases found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the role of mutations in evolution?

Back

Mutations can introduce genetic variation, which is essential for natural selection.

Front

What is the difference between a point mutation and a frameshift mutation?

Back

A point mutation involves a change in a single nucleotide, while a frameshift mutation involves the insertion or deletion of nucleotides, altering the reading frame.

Front

What is the significance of the double helix structure of DNA?

Back

The double helix structure allows for the stable storage of genetic information and facilitates replication.

Front

What is a silent mutation?

Back

A silent mutation is a change in the DNA sequence that does not alter the amino acid sequence of a protein.
