The enzyme telomerase solves the problem of replication at the ends of linear chromosomes by which method?

adell [148]

<h2>Answer </h2>

The method is by adding various small DNA chains such as TTAGGG, that develop a hairpin turn.

<u>Explanation </u>

The method is by adding various small DNA chains such as TTAGGG, that develop a hairpin turn. Telomerase is an RNA dependent DNA polymerase means an enzyme that can make DNA using RNA as a template. The ends of linear chromosomes called telomeres that protect genes from getting deleted as cells continue to divide. The telomerase enzyme attaches to the end of chromosome complementary bases to RNA template are added on 3 ends of the DNA strand.

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is inherited as an X-linked recessive allele in humans. A woman whose father

prohojiy [21]

Answer:

(a) 1/2; (b) no

Explanation:

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is an X-linked recessive disorder and the woman's father was diseased so it means that woman is a carrier of the allele but has normal phenotype. It means that she will have XXᵇ genotype.

In contrast to this, her husband is diseased so his genotype will be XᵇY.

The Punnett square diagram related to the cross is attached.

(a) Proportion of their sons expected to be G6PD is 1/2:

They both may give birth to 4 progeny with genotypes XXᵇ, XᵇXᵇ, XY and XᵇY. It means they both may have 2 sons out of which one with genotype XᵇY will be diseased while the one with genotype XY will be healthy. So the proportion of their sons having G6PD is 1/2 or 50%.

(b) If the husband were G6PD deficient, the answer will not change.

The reason behind this is that this disease is caused by an allele located in X chromosome. But father contributes only Y chromosome to his son not X chromosome. The X chromosome will affect the genotype of his daughter not son that is why answer will not change. It means they will still have 1/2 of their sons diseased.
