Answer:
production of new gene combination
Explanation:
cause it doesnt occur during meiosis
Answer:
A). The model does not predict energy flow.
Explanation:
As per the given details, the most probable constraint of using 'numerical computer-built models' would be their 'inability to forecast the energy that is flowing throughout the ecosystem.' However, they assist in offering collected information at the same time yet <u>its failure to predict the actual amount of energy flowing that will lead to a failure to predict if the ecological balance is being maintained or not</u>. As a result, some organisms may be deprived of the appropriate food to ensure their survival and their existence on this planet might be under threat. Thus, this is the limitation of using such-technology based models and hence, <u>option A</u> is the correct answer.
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.
