The answer to this question is gamete formation. During meiosis, the DNA is only replicated or copied once even if the cell is divided into four different cells. The formation of gamete segregates the gene pairs among the new cells.

Answer from: kiekie1986

The correct answer will be- Meiosis anaphase I and II.

Explanation:

The segregation of gene pairs usually takes place during the gamete formation which is formed by the meiosis.

During anaphase I and II, the chromosome containing the genes which determine the traits of an organism gets separated reaching the opposite poles of the cells through mitotic spindles.

The segregation of gene plays an important role in determining the trait of the organism as the alleles show their effect only when they come in pairs after fertilization.

Thus, Meiosis anaphase I and II is the correct answer.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

Answer from: Quest

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
