Tomtit [17]

Answer:

a. Only the DNA of β cells contains the gene for insulin; only the DNA of chief cells contains the gene for pepsinogen

Explanation:

As stated in the question above, insulin production is exclusive to β cells in the pancreas. This is because only these cells have a gene that manages the production and excretion of insulin within an organism. Similarly, only the main cells of the stomach have the capacity to produce pepsinogen, which indicates that the gene responsible for managing this production is unique to these cells.

What would happen if a cell did not have mitochondrial
Usimov [2.4K]
Cells that have no mitochondria are unable to convert oxygen into energy, found in the form of adenosine triphosphate (ATP). All multicellular eukaryotic organisms, including plants and animals, have mitochondria in some cells, but prokaryotes and some single-cell eukaryotes do not have mitochondria.

Cell at metaphase of mitosis contains 20 sister chromatids, how many chromosomes will be present in a g1 cell? if a cell at meta
kumpel [21]

Answer:

The correct answer would be 10.

The cell cycle can be divided into four phases namely gap 1 (G₁) phase , synthesis (S) phase, gap 2 (G₂) phase, and  mitosis (M) phase.

DNA (deoxyribonuceic acid) content is only replicated and doubled in the S phase. However, the chromosome number remains the same. It can be explained as the number of chromosomes remains the same (2n) but number of chromatids doubles (4n) after S phase.

The number of chromatids restores to 2n in daughter cells after completion of mitosis.

Hence, if number of chromatids in metaphase was 20 i.e. 4n then the number of chromosomes (2n) would be 10.

Hence, 10 chromosomes or 5 pairs of chromosome would be present in the cell during its G₁ phase.
