Mutations are a permanent change in the of DNA which most often occurs during .
The diagram below shows three types of mutations. Determine which type of mutation is shown in each box. Move ONE correct answer to each box. Not all answers will be used.
Different types of mutations can occur in DNA. The diagram represents a type of mutation:
Which statement describes the mutation in the diagram?
Sickle-shaped red blood cells result from a mutation in the gene that codes for hemoglobin. This mutation results in sickle-cell anemia. A partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia are shown below.
What type of mutation is depicted in this sequence?
Below is an mRNA codon chart.
Use the Codon Chart and your knowledge to answer the following questions.
Add "What is the amino acid for CGA?
(Multiple choice - 4 options)
From the codons provided in the answer choices below, which mutation to the mRNA codon CGA will affect the protein produced?
Observe the mutations in the diagram below.
Which mutations would cause a frameshift? Select TWO mutations.
Exposure to the building material "asbestos" has been linked to certain types of cancers. Asbestos causes mutations in the p53 gene, which controls tumor suppression.
Which statement best explains why people with cancer due to asbestos exposure do NOT pass the mutation on to their offspring?
A mutation is shown in the diagram below.
Based on the diagram, what kind of mutation has occurred?
Writing comparing 2 strands - MOST impactful Student A correct or incorrect and explain - 2 inline choice options
1st - correct or incorrect
2nd - describe the mutation
There are 64 possible codons listed on a Codon Chart; however, there are only 20 amino acids.
Which of the following is TRUE?
Due to excessive amounts of ultraviolet (UV) radiation, a mutation has occurred in the gene of a skin cell causing a Cytosine (C) to pair with Thymine (T). This gene is then transcribed incorrectly into mRNA and translated into a polypeptide (protein). However, the resulting protein shows no errors in its amino acid sequence.
Based on this information, what conclusion can be made?
Tay-Sachs disease is a genetic disorder in which the body does not produce the necessary enzymes to break down certain fatty acids. The buildup of these fatty acids eventually leads to failure of the nervous system. Researchers have discovered that this disease is caused by a substitution mutation.
Which of the following statements explains why a single nucleotide switch can result in a disease like Tay-Sachs?
