One oak tree cell with 14 chromosomes undergoes meiosis. How many cells will result from this process,???
Tomtit [17]

Answer:

Four (4) cells

Explanation:

Meiosis is the type of cell division in which four daughter cells that are genetically different is produced. The daughter cells are gametes that have undergone a reduction in their chromosome number (by half).

For example, one cell of an oak tree with 14 chromosomes is said to undergo meiosis. This means that, based on the explanation of meiosis above, the oak cell will give rise to four (4) daughter cells containing 7 chromosomes each.

What happens to DNA after RNA polymerase has synthesized a mRNA molecule?
schepotkina [342]
Synthesized RNA will remain. I believe this is because the polymerase allows the DNA to close up & that’s how it forms its double helix. Then the RNA chain is displaced and the DNA will soon be re-formed.
