The protein that uses ATP hydrolysis to separate the two DNA strands during replication is called helicases.

DNA is the genetic material present in majority of the living organisms. It is a double stranded DNA molecule that is helical in shape with anti-parallel strands. The constituents of DNA are: deoxyribose sugar, phosphate group and the 4 nitrogenous bases: adenine, guanine, cytosine and thymine.

Replication is the process of making a duplicate copy of DNA. The process occurs in the nucleus of the eukaryotic cell and the nucleoid of the prokaryotic cell. Both the strands of a DNA molecule act as the template strand for DNA synthesis.

Energy expenditure describes how much a person uses during physical activity and to maintain vital bodily processes like respiration, circulation, and digestion. Even when the body is at rest, it needs energy (kilojoules) to keep all of its systems running smoothly. This is known as the basal metabolic rate (BMR) (such as breathing, keeping the heart beating to circulate blood, growing and repairing cells and adjusting hormone levels). The energy used up while movement is known as physical activity energy expenditure, or PAEE.

The following statements are untrue: Prokaryotic cells and viruses do not use enzymes; enzymes are exhausted after catalysing a process, and enzymes exclusively function inside cells.

Enzymes can be utilised again to speed up the same reaction because they don't get damaged or depleted during the reactions they catalyse. Enzymes are incredibly efficient because each one is very specialised for the chemical reaction it catalyses. One way to think of enzymes is as metabolic process catalysts. As they are not involved in the actual reaction but rather offer a different reaction pathway with lower activation energy, catalysts are not depleted throughout reactions.

By heating the substance, it is possible that the substances react to form the product. Heating a substance will increase the kinetic energy of the substance. Thus, the correct option is E.

A chemical reaction is a process during which one or more substances, known as reactants, are converted to different substances, known as products. The substances are either chemical elements or compounds depending upon the reactants.

Heating the solution will result into formation of product as an increase in temperature will typically increases the rate of reaction by increasing the average kinetic energy of the reactant molecules in a solution.

The point where the axon terminal synapses with the muscle fiber sarcolemma is called the neuromuscular junction.

The neuromuscular junction (NMJ) is a highly specialized synapse between a motor neuron nerve terminal and its muscle fiber that are responsible for converting electrical impulses generated by the motor neuron into electrical activity in the muscle fibers. On arrival of the motor nerve action potential, calcium enters the presynaptic terminal, which leads to the release of the neurotransmitter acetylcholine (ACh).

ACh crosses the synaptic gap and binds to ACh receptors tightly clustered on the surface of the muscle fiber, this leads to the endplate potential which initiates the muscle action potential that results in muscle contraction.

The amount of air pressure in the area where the soccer ball is kicked can affect its trajectory and distance traveled. If the air pressure is lower, the ball may travel further due to less resistance from the air. On the other hand, if the air pressure is higher, the ball may not travel as far due to increased resistance from the air. Therefore, understanding the relationship between air pressure and the distance a soccer ball travels when kicked can be useful in predicting and analyzing the performance of a soccer player or team.

Linked genes are too close to each other, so most of them can not distribute independently and there are few recombination events between them. Part 1: 1) Yyll and yyLl. 2) 20 mu. Part 2: 1) YyBb and yybb. 2) Yybb and yyBb. 3) 16 mu. Part 3: 1) LlBb and llbb. 2) 4mu. Part 4: 1) Y-L: 20MU, Y-B: 16 MU, L-B: 4MU. 2) Y-L. 3) L-B. 4) True.

Genes located too close to each other on the same chromosome can not segregate independently. They do not exhibit an independent distribution and inherit together more frequently. These are linked genes.

We must observe the progeny distribution to know if two genes are linked.

Crossing over between linked genes is not that common. In this way, we can recognize the recombinant genotypes by looking at the phenotypes with the lowest frequencies among the progeny.

Recombination frequency between these genes can be calculated by using the formula

P = Recombinant number / Total of individuals.

The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU).

The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant product.

In the present example:

400 YyLl

100 Yyll

100 yyLl

400 yyll

1. Which offspring are the recombinant offspring in this cross?

Yyll and yyLl are the genotypes with the lowest frequency, so we can assume these are the recombinant individuals.

2. How far apart are Y and L?

P = Recombinant number / Total of individuals

P = 100 + 100 / 1000 = 0.2

MU = P x 100 = 0.2 x 100 = 20 mu

Cross: one parent that is heterozygous for both beak color and feather color with a parent that is homozygous for both recessive traits.

Parentals) YyBb   x   yybb

80 Yybb

80 yyBb

420 yybb

1. What are the genotypes of the parents?

YyBb and yybb

2. Which offspring are the recombinant offspring in this cross?

Yybb and yyBb are the genotypes with the lowest frequency, so we can assume these are the recombinant individuals.

3. How far apart are Y and B?

P = Recombinant number / Total of individuals

P = 80 + 80 / 1000 = 0.16

MU = P x 100 = 0.16 x 100 = 16 mu

Parentals) LlBb  x  llbb

F1)

480 LlBb

20 Llbb

20 llBb

480 llbb

1. Which offspring are not the recombinant offspring in this cross?

LlBb and llbb are the genotypes with the highest frequency, so we can assume these are not the recombinant individuals.

2. How far apart are L and B?

P = Recombinant number / Total of individuals

P = 20 + 20 / 1000 = 0.04

MU = P x 100 = 0.04 x 100 = 4 mu

The F1 progeny from this cross would all have pea combs. The F2 progeny would have a phenotypic ratio of 3:1—three pea combed chickens for every one rose combed chicken.

The progeny of a homozygous rose combed hen crossed with a homozygous pea combed rooster would be a combination of both rose and pea combs. The phenotypic ratio of the F2 progeny would be 3 rose combs: 1 pea comb.

To explain this ratio, we can look at the Punnett square for this cross. The Punnett square for this cross would look like this:

Hen (RR)  |  Rooster (PP)

-------------------

R | R

R | P

In this Punnett square, the hen is homozygous for the rose comb gene (RR) and the rooster is homozygous for the pea comb gene (PP). The offspring, therefore, would all be heterozygous (Rp) for the rose and pea comb genes.

The F2 progeny would then be a 3:1 ratio of rose combs to pea combs. This is because the heterozygous (Rp) offspring would all have a dominant rose comb allele and a recessive pea comb allele. The offspring would have a 3:1 chance of inheriting the dominant rose comb gene,
