point mutation
choose
choose
extra bases are removed from the dna or rna sequence
extra bases are placed within the dna or rna sequence
any change that results in the codons of the mrna being read differently
a single nitrogenous base is changed in the nucleotide sequence
insertion
deletion
frameshift mutation
choose

Explanation:

• Point mutation: A single nitrogenous base is changed in the nucleotide sequence. This is the classic definition of a point mutation where only one base - pair is altered.
• Insertion: Extra bases are placed within the DNA or RNA sequence. Insertion mutations add one or more nucleotide bases to the sequence.
• Deletion: Extra bases are removed from the DNA or RNA sequence. Deletion mutations remove one or more nucleotide bases from the sequence.
• Frameshift mutation: Any change that results in the codons of the mRNA being read differently. Frameshift mutations (such as insertions or deletions that are not in multiples of three) disrupt the reading frame of the mRNA, causing a different set of codons to be read.

Answer:

• Point mutation: a single nitrogenous base is changed in the nucleotide sequence
• Insertion: extra bases are placed within the DNA or RNA sequence
• Deletion: extra bases are removed from the DNA or RNA sequence
• Frameshift mutation: any change that results in the codons of the mRNA being read differently
