A parent cell divides to form two genetically identical daughter cells in the process of mitosis. For mitosis to take place:
A.
the parent cell must divide its DNA in half so each daughter cell gets only the genes needed to carry out its functions. In this way, differentiation occurs.
B.
the parent cell must reproduce its DNA during telophase
C.
the parent cell must first be fertilized
D.
the parent cell must replicate its entire genome prior to mitosis
E.
crossover must be delayed until the second cell division
Extranuclear inheritance occurs due toa. chromosomes that may become detached from the spindleapparatus during meiosis.b. genetic material that is found in chloroplasts andmitochondria.c. mutations that disrupt the integrity of the nuclearmembrane.d. none of the above
A cytoplasmic determinant can control development at the early stages of development because....?
Group of answer choices
a. it is a universal activator of all genes
b. it is present evenly throughout the cytoplasm
c. it is activated by cell division
d. it is controlled by genes present in the cytoplasm
e. it is laid down in the egg cell by the mother

Block the production of ATP by the ribosomes. c. Interfere with the ability of the fetal cells to replicate. d. Cause nondisjunction of the chromosomes, causing fetal cells to have two of each chromosome instead of three.arrow_forwardWhich of the following situations does not describes a chromosomal mutation? Select one: a. A cytosine nucleotide is substituted for thymine nucleotide in a gene. b. A portion of Chromosome 4 is deleted during interphase of meiosis. c. The sister chromatids of Chromosome 18 do not separate during anaphase II. d. A section of Chromosome 17 is duplicated leading to problems in the peripheral nervous system.arrow_forwardWhy are dominant mutations in proto-oncogenes generally not inherited? A. Inherited mutations in proto-oncogenes would not affect cell division rate B. Inherited mutations in proto-oncogenes would decrease cell division rate and no viable embryo would form C. Inherited mutations in proto-oncogenes would increase cell division rate and no viable embryo would form D. Dominant mutations in proto-oncogenes are always inheritedarrow_forward

- Describe the role of the following structures or proteins in cell division: a. microtubules b. cohesin protein c. kinetochores d. synaptonemal complexarrow_forwardA researcher performs a tissue transplant experiment with an early Drosophila embryo. The researcher observes that transplanting tissue from the area of the embryo that normally becomes the head of the fly to the bottom part of an embryo does not alter the embryological development of that organism. What to conclude from that observation? This observation remains to be explained. The embryo does not produce sufficient survival factors to maintain the transplanted cells. The cell fate of the transplanted cells had not yet been determined. O The transplanted cells all activate the apoptosis response, and thus do not affect the developmental program.arrow_forwardWhich of the following statements is true regarding cell cycle regulators? a.
