how does the random alignment of homologous chromosomes contribute to genetic variation in a population
SCORPION-xisa [38]

The assortment of homologous chromosomes during meiosis is random and generates genetic variation, the raw material for evolution.

During metaphase I of meiosis, homologous chromosomes are lined up at the equator plate of the cell in order to be separated (assorted) in anaphase I.

The separation of homologous chromosomes during meiosis I is random. Daughter cells receive unique gene combinations from an original parent cell.

Subsequently, haploid cells got from two successive meiotic divisions fuse during fecundation to form a diploid (2n) zygote.

During prophase I, non-sister chromatids interchange genetic material by a process known as recombination. This genetic process also increases genetic variation in daughter cells.

In conclusion, the assortment of homologous chromosomes during meiosis is random and generates genetic variation.

Which of the following
Pachacha [2.7K]

Phosphate groups of the nucleotides in the diagram are marked with W.

Option C.

<h3><u>Explanation:</u></h3>

DNA is a macro molecule which is formed of polymerization of deoxyribonucleotides. Four types of deoxyribonucleotides are present which are adenosine, guanosine, thymidine and cytosine triphosphate. These nucleotides are polymerized based on the genetic setup.

The phosphate groups attached with the sugar molecule are actually polymerized with the o glycosidic bond. That's marked with the letter W. These phosphate molecules are attached with the sugar molecules which actually are attached with the nitrogen bases. They in total forms a nucleotide, hence the whole DNA. X in the diagram are nitrogen bases and the Y are the hydrogen bonds between the complementary nitrogen bases

How is natural selection similar to selective breeding? How is natural selection different from selective breeding?
shusha [124]

Answer:

Natural selection and selective breeding can both cause changes in animals and plants.the difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. for this reason selective breeding is sometimes called artificial selection.

Jack was sick with a cold and fever. the doctor prescribed him erythromycin, an antibiotic. analyzing the process of translation
KatRina [158]

Answer:

This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.

This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore, humans or sick cells do not have the active site to which the drug binds.

Explanation:

This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.

This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore humans or host cells do not have the active site to which the drug binds.

Erythromycin falls into the macrolide family and is considered a drug that is bacteriostatic at low concentrations and bactericidal at very high concentrations.

The difference between these named terms is that one ends the life of the bacterium (bactericidal) and the other stops the bacterial metabolism preventing its possibility of increasing in number.
