Answer:

Crossing over

Explanation:

During prophase I of meiosis, homologous chromosomes pair to form bivalents. The chromatids of bivalents may form intimate contact points called chiasmata. At the chiasmata breakage may occur and exchange of chromatids segments between non sister chromatids may take place. This is crossing over ad results in new gene combinations causing variations.

A researcher incubates a cell with radiolabeled amino acids. These amino acids are incorporated into the proteins as they are sy
AURORKA [14]

Answer:

The incorporation of radiolabeled amino acids during protein synthesis occurs when the data shows the organelles involved with protein synthesis, packaging and transport, that is, radioactivity levels would increase first at the rough endoplasmic reticulum, followed by the Golgi, and then the secretory vesicles (option C).

Explanation:

Protein synthesis in the cell occurs when RNA -which contains the sequence of triplets or codons that make up the genetic code- is coupled to ribosomes.

Each codon or triplet, consisting of three nucleotides, will give instructions for specific amino acids to be incorporated into the polypeptide chain that is being synthesized in the rough endoplasmic reticulum.

The Golgi apparatus is responsible for packaging or packaging the newly synthesized proteins in secretory vesicles for transport.

<em>In consecuense, </em><u><em>radioactivity levels would increase in the organelles involved in protein synthesis, packaging and transport, the rough endoplasmic reticulum, Golgi apparatus and secretory vesicles</em></u><em>, respectively.</em>

The ability of one person to produce over a million different antibody molecules does not require over a million different genes
Tema [17]

Answer:

DNA rearrangment.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

The human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.

On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.

Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.

DNA rearrangment can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

Hence, the ability of an individual to produce over a million different antibody molecules doesn't require the use of over a million different genes; rather, this wide range of antibody production is due to deoxyribonucleic acid (DNA) rearrangment.
