What effect would a Primase inhibitor have on DNA replication?

What effect would a Primase inhibitor have on DNA replication?

DNA primase, an essential component of the DNA replication machinery of every living cell5, synthesizes short RNA primers that are used by DNA polymerase to form the “Okazaki fragments” on the lagging DNA strand. The inhibition of primase, therefore, will halt DNA replication and, as a result, cell proliferation.

Which of the following is not required for DNA replication?

Which of the following proteins is not necessary during DNA replication? Explanation: RNA polymerase is an enzyme that transcribes RNA from DNA; it is not essential for DNA replication.

Which mechanism causes induced mutations to occur?

DNA Damage and Mutations Mutations, variations in the nucleotide sequence of a genome, can also occur because of damage to DNA. Such mutations may be of two types: induced or spontaneous. Induced mutations are those that result from an exposure to chemicals, UV rays, X-rays, or some other environmental agent.

Why is DNA replication such an important process?

Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

What are the 5 types of gene mutations?

What kinds of gene variants are possible?

• Missense. A missense variant is a type of substitution in which the nucleotide change results in the replacement of one protein building block (amino acid) with another in the protein made from the gene.
• Nonsense.
• Insertion.
• Deletion.
• Duplication.
• Frameshift.
• Repeat expansion.

What is an example of a positive mutation?

Examples of beneficial mutations include HIV resistance, lactose tolerance, and trichromatic vision.

What is the result of genetic drift?

Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation, or rise to 100% frequency, of other alleles.
