The answer is <span>Topoisomerase.
Topoisomerase is an enzyme responsible for twisting of DNA helix. After DNA strand is untwisted by helicase enzyme, DNA must be twisted again so the normal function of DNA can be sustained. If left untwisted, the replication fork will continue to grow, the normal function of DNA will stop.</span>
Glycolysis results in the formation of 2 ATP molecules, 2 Pyruvic Acid molecules (Or Pyruvate), and 2 NADH molecules.
Answer:
1. 8 copies of each gene in somatic cells
2. 4 copies of each gene in gametes
Explanation:
According to the question, strawberry is an octoploid organism (8n). This means that it contains 8 sets of chromosomes in its genome. If it contains 8 copies of each chromosome, then it also contains 8 copies of each gene in its body or somatic cell (4 copies from each parent).
However, it will produce gametes or reproductive cells via meiosis. Meiosis is a kind of cell division that reduces the chromosomal number by half. Hence, an octoploid strawberry (8n) with 8 copies of genes will undergo meiosis to produce gametes that have 4 copies of each chromosome and hence, four copies of each gene i.e. 4n (tetraploid).
