Difference Between Intragenic and Extragenic Suppressor Mutation

Difference Between Intragenic and Extragenic Suppressor Mutation

Whereas extragenic suppressors provide information about other proteins that cooperate with pUL34, intragenic suppressors (mutations within UL34) provide information about other residues and sequence regions of UL34 that contribute to the wild-type phenotype.

What does a suppressor mutation suppress what is the difference between an Intragenic and an intergenic suppressor?

What is the difference between an intragenic and an intergenic suppressor? Suppressor mutation is a second type of mutation that recovers the phenotypic effect of another mutation, which occurred earlier. If a mutation alters any phenotypic characters, suppressor mutation restores the normal wild type phenotype.

What is intragenic suppressor mutation?

Intragenic suppression results from suppressor mutations that occur in the same gene as the original mutation. ... used intragenic suppression to study the fundamental nature of the genetic code. From this study it was shown that genes are expressed as non-overlapping triplets (codons).

What is intergenic suppression?

A mutation at a second locus that apparently restores the wild-type phenotype to a mutation at a first locus. Return to Search Page.

What is a conditional mutation?

A mutation that has the wild-type phenotype under certain (permissive) environmental conditions and a mutant phenotype under other (restrictive) conditions.

What is an example of a silent mutation?

Silent mutations are base substitutions that result in no change of the amino acid or amino acid functionality when the altered messenger RNA (mRNA) is translated. For example, if the codon AAA is altered to become AAG, the same amino acid – lysine – will be incorporated into the peptide chain.

What causes a transition mutation?

Transition, in genetics and molecular biology, refers to a point mutation that changes a purine nucleotide to another purine (A ↔ G), or a pyrimidine nucleotide to another pyrimidine (C ↔ T). ... Transitions can be caused by oxidative deamination and tautomerization.

What is silent gene?

Silent genes are generally found in more compact regions of chromatin, termed heterochromatin, while active genes are in regions of euchromatic chromatin which is less compact and more permissible for proteins to bind.

What is reverse mutation?

Reverse mutation, also called reversion, denotes any mutationall process or mutation that restores the wild-type phenotype to cells already carrying a phenotype-altering forward mutation. Forward mutations confer a gene sequence and phenotype different from that conferred by the wild-type gene.

What is a Revertant?

: a mutant gene, individual, or strain that regains a former capability (such as the production of a particular protein) by undergoing further mutation yeast revertants.

Which three types of mutations are classified as reversion mutations?

Which three types of mutations are classified as reversion mutations? A second mutation that restores the original wild-type sequence. A second mutation creates a codon that replaces the wild type amino acid with a similar amino acid. A second mutation that creates a new codon that codes for the wild type amino acid.

How do insertions and deletions arise?

An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication. ... Strand slippage can also lead to deletion mutations. A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand (Figure 3).

Is mutation predestined?

Explanation: Mutations are the ultimate source of all genetic variations and without which all the genes could exist in only one form. 4. Which of the following is NOT a type of reverse mutation? Explanation: Reverse mutation occurs at the same or different sites of forward mutation and restores wild phenotype.
