Question

1 multiple choice 1 point what is a point mutation? multiple nucleotides are inserted or deleted. a change in a single nucleotide in the dna sequence. a large segment of chromosome is deleted. an entire gene is duplicated. 2 multiple choice 1 point a silent mutation is a type of point mutation that changes the amino acid coded by the gene. does not change the amino acid coded by the gene. causes a frameshift in the gene sequence. deletes a nucleotide from the gene.

Explanation:

1. A point - mutation is defined as a change in a single nucleotide in the DNA sequence. Other options describe different types of genetic alterations.
2. A silent mutation is a type of point - mutation where the change in the DNA sequence does not change the amino acid coded by the gene due to the degeneracy of the genetic code.

Answer:

1. A change in a single nucleotide in the DNA sequence.
2. does not change the amino acid coded by the gene.
