Answer:

X represents nitrogen base pairs-  adenine, thymine, guanine, and cytosine.

Explanation:

DNA molecule is a molecule that carries genetic information for growth, functioning, development, and reproduction. It is composed of nucleotides that contain a phosphate group, a sugar group, and nitrogen bases (adenine, guanine, thymine, and cytosine).

Nucleotides are linked together to form two long strands that coiled spirally to create a structure called a double helix. Just think of the double helix as a ladder. The phosphate and sugar groups would be the two sides of the ladder, while the nitrogen bases would be the rungs of the ladder. The bases adenine pairs with thymine, while guanine pairs with cytosine.

Thus, the correct answer would be base pairs.

Describe how proteins are made, packaged and transported within the cell.
nalin [4]
Lol . To answer your question, proteins in animals are made by the consumption of food. They are packaged in a way where they are broken down and converted into energy, sugars and PROTEINS. They are transported and aided with the Golgi Apparatus. If you need more help I would just search each peice of your question individually

An albino woman marries a phenotypically normal man with no family history of albinism. What percentage of their children are li
maw [93]

Answer:

0%

Explanation:

This involves a single gene coding for melanin pigment in the skin. The recessive form of this gene (allele) is albinism while the dominant form is a normal skin. The question highlights that the normal male parent (dominant) has no family history of albinism, this means that nobody in their family has ever possessed albinism or has been a carrier/heterozygous for the trait. This is because a carrier/heterozygote will always produce the recessive trait (albinism) if crossed with another carrier or albino individual.

In a nutshell, the normal male parent is homozygous for the dominant trait. Hence, if a homozygous dominant male is crossed with an albino woman (homozygous recessive), all their offsprings will possess a heterozygous genotype and dominant phenotype. Meaning that none of their children will ba an albino.

Hence, the percentage of their child being an albino is 0.

Nondisjunction during meiosis results in an abnormal number of chromosomes in one or more gametes. In some cases of nondisjuncti
den301095 [7]

Answer:

haploid (n) or triploid (3n)

Explanation:

If none of the chromosomes separate during meiosis, the resulting gametes will either lack chromosome or have diploid number (2n) of chromosome instead of a haploid number.

If an egg without chromosome (o) fertilizes a normal sperm (n), the resulting zygote will have haploid number (n) of chromosome.

If an egg with diploid number of chromosome (2n) fertilizes a normal sperm (n), the resulting zygote will be a triploid with 3n number of chromosome.
