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 answer is <u>a bite or sting.</u>
<u />
We would classify an environmental emergency in which a child stepped on a sea urchin and got the spine embedded in his foot, by a bite or a sting.
What is environmental emergency?
Any "sudden-onset disaster or accident caused by natural, technical, or human-induced forces, or a mix of these, that causes or threatens to cause serious environmental damage as well as loss of human lives and property" is referred to as an environmental emergency. 13 November 2002 (UNEP/GC.22/INF/5).
An environmental emergency can happen after a disaster or conflict when the ecosystem has been significantly damaged or when the release of toxic or hazardous substances is endangering human health and livelihoods. Fires, oil spills, chemical mishaps, the disposal of toxic waste, and groundwater pollution are a few examples.

Answer: bat, black widow spider, bighorn sheep, and bobcat
There are two processes that are involved in the production of Adenosine Triphosphate or ATP and these are fermentation and cellular respiration. However, during fermentation on 2 ATP molecules are produced while in cellular respiration, 38 ATP molecules are produced.
So the answer would be Cellular respiration produces more ATP molecules than fermentation.
