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.

Answer:
Explanation:
Well a person can be asymptomatic for loads of viruses not just coronavirus. There is no way of knowing if someone is asymptomatic without having a test done. Many asymptomatic people will go on to get a test and then show symptoms a few days or so later.
Answer:
Cellular organization.
Reproduction.
Metabolism.
Homeostasis.
Heredity.
Response to stimuli.
Growth and development.
Adaptation through evolution.
Explanation:
Hope this helps.
One reason is that the two kinds of birds live in two different types of environments and also the sharp billed ground finch does not just it plant matter. It feast on the blood of bigger sea birds. This is an adaptation that it has so it does not have to eat plant matter and compete for food
