Which of the following can act as an intragenic suppressor mutation to a frameshift mutation?
Which of the following can act as an intragenic suppressor mutation to a Frame shift mutation? Explanation: If overall the two frame shift mutations lead to a change of 3 or its multiple in the genetic code, the codons will again be in the same frame. This is an internal compensation, so intragenic suppression.
What is Extragenic suppressor?
Extragenic suppression — overview Suppressing the effects of a mutant gene by changes elsewhere in the genome can occur in a number of ways. Extragenic suppression is usually revealed by crossing a revertant line with wildtype, and observing the re-appearance of the original mutant after Mendelian segregation.
What is intragenic recombination?
Rearrangement or intragenic recombination describes the insertions, deletions, and more commonly, gene duplications leading to sudden changes in the structure of genome segments. Normally, in gene duplications, the coding region of the template fragment remains unimpaired.
What does a suppressor mutation suppress?
A suppressor mutation is a second mutation that alleviates or reverts the phenotypic effects of an already existing mutation in a process defined synthetic rescue. Genetic suppression therefore restores the phenotype seen prior to the original background mutation.
What is a second site suppressor?
Identifying rescue mutations, often referred to as second-site suppressor mutations, controls against scenarios in which the initial deleterious mutation inactivates the protein or disrupts alternative protein-protein interactions.
What was a key finding of Intragenic mapping?
A key finding of intragenic mapping was: A) that genes consist of indivisible particles, like beads on a string. B) that genes do not change over time.
What is Intragenic?
Definition of intragenic : being or occurring within a gene intragenic recombination intragenic mutation.

What is the difference between intragenic and intergenic suppressor mutation?
The effect is another difference between intragenic and intergenic suppressor mutation. Intragenic suppressor mutation relieves the effect of a primary mutation within the same gene while intergenic suppressor mutation relieves the effect of a primary mutation somewhere else in the genome.
What is suppressant mutation?
suppressor mutation. a MUTATION that acts to restore the normal functioning of another gene located elsewhere in the GENOME (intergenic suppression), or another mutation at a different site in the same gene (intragenic suppression).
What are the two types of gene suppression?
Genetic changes such that the effect of a mutation in one place can be overcome by a second mutation in another location. There are two types: intergenic suppression (occurring in a different gene) and intragenic suppression (occurring in the same gene but at a different site).
