Answer:

DNA ligase is an enzyme which can connect two strands of DNA together by forming a bond between the phosphate group of one strand and the deoxyribose group on another.

DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, which are the building blocks of DNA. The enzymes play an essential role in DNA replication, usually working in pairs to produce two matching DNA stranges from a single DNA molecule.

DNA gyrase is an essential bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA

Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.

The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square m
max2010maxim [7]

Given: The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square meters.

To find: The total population size of the frogs in the pond.

Method: Using unitary method of proportions

Solution:

Let p be the density of the frogs present per square meter.

Let A denote the total area of the pond.

∴ p = 12 frogs/m² and A = 370 m²

The total number of frogs in the pond is given by,

p \times A = 12 \times 370 = 4440

Therefore, there are 4440 frogs in the pond.

[ANSWER INCLUDING]

The mother's genotype can be either X^AX^A or X^AX^a.

For X-linked recessive traits, males (XY) can either be affected or free from the disorder, they cannot be carriers. Females (XX), on the other hand, can be affected, unaffected, or be carriers.

The circled male child is free from the disorder (X^AY) while the females are carriers (X^AX^a).

The male inherited the healthy allele, X^A, from the mother.

The female children inherit the affected allele from their father (who is affected for the disorder) and the other healthy allele from their mother.

This means that the mother cannot be affected for the disease. As it is, the pedigree points that all the children got their healthy alleles from their mother. This does not mean the mother has two healthy alleles though.

Thus, the possible genotype of the mother are X^AX^A and X^AX^a.
