Which of the following describes a frameshift mutation?

Which of the following types of mutation refers to the presence of a premature stop codon?

Which of the following is NOT a potential result from a point mutation that substitutes a single nucleotide in a gene?

Scientists were examining the maize genome. They had two specimens: one control and one specimen that had undergone mutagenesis. They saw that the mutant specimen underwent a knockout caused by a nucleotide switch in the DNA. Is this a dominant or recessive mutation?

Scientists were examining the maize genome. They had two specimens: one control and one specimen that had undergone mutagenesis. They saw that the mutant specimen underwent a knockout caused by a nucleotide switch in the DNA. However, when they compared gene sequences, they saw no change in size. Which type of mutation had most likely occurred?

The starting sequence of a gene changed from AUGTTCGACGTG to AUGTTTCGACGTG. What type of mutation is this?

Scientists studying the genetics of a congenital disease analyzed the chromosomes of the patient and found a large portion of chromosome twenty-three in chromosome one, and a small part of chromosome one in chromosome twenty-three. What is this an example of?

Which of the following mutations will not result in a change to the amino acid sequence of a protein?

A single nucleotide polymorphism changes one nucleotide in a gene sequence. As a result, the gene gains a stop codon 500 base pairs to soon and the protein—when it is translated—is truncated or cut short. Which of the following types of mutations did the point mutation cause?

A transition is a mutation that includes a purine mutating to another purine or a pyrimidine mutating to another pyrimidine.

Which option shows a transition mutation?
