Molecular and Cellular Biology Part 2

The reactants of photosynthesis are the products of cellular respiration and vice versa.

The reactants of photosynthesis are the reactants of cellular respiration.

The products of photosynthesis and cellular respiration are the same.

None of the above

Carbon dioxide + water + light > glucose + oxygen

Glucose + Oxygen > ATP + carbon dioxide + water

Glucose > ATP + oxygen

Carbon dioxide + glucose > oxygen + water

absence of cyclins in the DNA

uncontrolled cell growth caused by mutations in the p53 gene that control the cell cycle

multiple gene mutations on a chromosome of DNA

presence of genetic defects caused by hereditary disorders

The sister chromatids of each chromosome separate and move toward opposite poles

The two homologs of each chromosome pair separate and move toward opposite poles, reducing the chromosome number by half

A cleavage furrow appears, and by the end of this stage the parent cell has divided into two daughter cells

Crossing-over occurs between the duplicated homologous chromosomes pair

During anaphase, the spindle fibers split the cells in half, creating two daughter cells.

During anaphase, the spindle fibers ensure that each daughter cell has half the number of chromosomes as the parent cell.

During anaphase, the spindle fibers help maintain the chromosome number, ensuring that each daughter cell has the same number of chromosomes as the parent cell.

During anaphase, the spindle fibers ensure that each daughter cell has twice as many chromosomes as the parent cell.
