How does crossing over add to the genetic diversity of sexually reproducing organisms?
neonofarm [45]
<span>Crossover is the first way that genes are shuffled to give rise to genetic diversity. Crossover takes place in sexual reproduction. Chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other. When they break at the same place (locus) in the sequence of base pairs, the result is an exchange of genes called genetic recombination. That is the normal way for crossover to occur. Genetic recombination ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity is created.</span>

The distribution of melanosomes in cells is tightly regulated in animals that rapidly change color. dark-colored cells have mela
kipiarov [429]

Microtubules originate on the centre of the cell taking the positive end to the periphery of the cell, while the negative end remains turned to the centre of the cell. The melanosomes move along these microtubules using motor proteins desiganted kinesins and dyneins. The kinesins are responsible for moving the melanosomes to the positive end of the microtubule (periphery of the cell) generating dark-colored cells, whereas dyneins move the melanosomes to the negative end of the microtubule (centre of the cell) generating light-colored cells.

A. stomach distention

B. the production of saliva

C. the thought of food

D. the production and secretion of gastrin.

Answer:

C. the thought of food

Explanation:

Readme [11.4K]

Answer:

The correct answer is 3 prime OH.

Explanation:

The joining of nucleotides takes place by a condensation reaction, which discharges a small, stable molecule. Unlike carbohydrates, proteins, and lipids, the molecules, which is discharged is not water, however, a pyrophosphate, that is, two phosphate groups combined together.  

In the polymerization of DNA, a phosphodiester bond is formed between a free 5 prime phosphate group at one terminal and a free 3 prime hydroxyl group at the other end. The naming of these sequences is done from 5 prime to 3 prime.
