Confirm that the sample has both helicase and primase activities, but not the ability to synthesize DNA
- The replisome is a multiprotein-RNA complex that is required for the replication of DNA. The replisome consists of different proteins which include:
1. Helicase enzymes that unwind and separate the DNA strand
2. Replication factor C (RFC), a DNA-dependent ATP that acts as an activator of DNA polymerase.
3. Proliferating cell nuclear antigen (PCNA)
4. DNA gyrase/topoisomerase that cuts and reseals DNA strands, which is essential for DNA synthesis.
5. Primase enzyme that synthesizes short RNA fragments called primers.
6. DNA polymerase III, an enzyme that catalyzes the polymerization of deoxyribonucleotides into a DNA strand.
7. DNA ligases enzymes that form phosphodiester bonds at a single-strand break in DNA
- A primosome is a multiprotein complex responsible for creating RNA primers on single-stranded DNA (ssDNA) during the replication process.
- The primosome is composed of different primase and helicase enzymes. In<em> Escherichia coli</em>, it consists of PriA helicase, PriB, PriC, DnaB helicase, DnaG (encoded by the dnaG gene), DnaC and DnaT primase.

The speed of a chemical reaction when a catalyst is present is that it. A.) It speeds up
Answer:
The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.
Explanation:
Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.
With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.
Answer: Kingdoms
Explanation: Instead of the way the look, use it by the genes and other relationships of each animals
