Describe the process of DNA replication, including the role of enzymes involved.

DNA replication is a process that involves the unwinding of the double helix, followed by the synthesis of a new complementary strand by DNA polymerase.

DNA replication is a process that involves the conversion of DNA into RNA.

DNA replication is a process that involves the translation of mRNA into proteins.

DNA replication is a process that involves the transcription of DNA into mRNA.

Explain how a mutation in the DNA sequence can lead to a change in phenotype.

A mutation in the DNA sequence can lead to a change in phenotype by altering the sequence of amino acids in a protein, potentially affecting its function.

A mutation in the DNA sequence always results in a beneficial change in phenotype.

A mutation in the DNA sequence has no effect on phenotype.

A mutation in the DNA sequence only affects the phenotype if it occurs in non-coding regions.

Evaluate the potential impact of a point mutation in a gene coding for an enzyme.

A point mutation in a gene coding for an enzyme will always result in a non-functional enzyme.

A point mutation in a gene coding for an enzyme may alter the enzyme's active site, potentially reducing or enhancing its activity.

A point mutation in a gene coding for an enzyme has no effect on the enzyme's function.

A point mutation in a gene coding for an enzyme will always enhance the enzyme's activity.
