The reason that there are Okazaki fragments during DNA replication is ultimately because:

rusak2 [61]

Answer:

B) Polymerases can only synthesize in the 5' to 3' direction

Explanation:

The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.

A body cell has been growing and synthesizing proteins. In the nucleus of this body cell, DNA replication is taking place, and a

goblinko [34]

The best conclusion you can make about the life cycle of this cell is that the cell is in the S phase of interphase and will move next to the G2 phase.

S phase (Synthesis Phase) is the phase of the cell cycle in which all of the chromosomes (DNA) are replicated within the nucleus. During this phase, the DNA is effectively doubled as each chromosome contains two sister chromatids. After the S phase, the cell enters the G2 phase where various proteins (such as microtubules) are synthesized.

The process of photosynthesis can be represented by the chemical formula A) C6H12O6 + 6O2 → 6CO2 + 6H2O + energy B) C6H12O6 + 6H

mrs_skeptik [129]

C) is correct because light energy is converted into glucose in the process of photosynthesis.Also the air we breath in aka oxygen is exhaled as carbon dioxide which plants convert. into oxygen.Products of photosynthesis are the reactants of cellular resperation.
