Homework Answers
Q6) The answer is C.
Genetic diversity is enhanced by mitosis.
explanation
Genetic diversity is not enhanced by mitosis, but enhanced by meiosis in 3 ways, they are : random fertilization, chromosomal crossover & independent assortment.
Q9) DNA template
explanation
Transcription utilizes the DNA template to produce RNA & in translation, this RNA produced during the transcription supplies the information from deoxyribonucleic acid & to the protein producing machines.
hope it helps.

A Which of the following does NOT occur during mitosis? condensation of the chromosomes replication of the DNA spindle formation separation of sister chromatidsB. Which of the following statements regarding the function of mitosis is false? Mitosis promotes genetic diversity. Mitosis is necessary for asexual reproduction in eukaryotes. Mitosis promotes repair tissues. Mitosis allows organisms to grow.C. At the end of which phase of cell division are the daughter cells half the ploidy (n) of the original parent cell (2n)? after Mitosis after Mitosis and MeiosisⅠafter MeiosisⅠafter Meiosis II

This question concerns cell division. For each of the following statements, say whether it is true for mitosis only, meiosis only, both, or neither (1 mark per statement): (a) The DNA is replicated before cell division starts. (b) The homologous chromosomes pair up during division. ( c) The cell divides only once during the process. (d) The daughter cells contain precisely the same genetic material as each other. (e) The number of chromosomes in each cell increases during the process...

What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...
