Leading and lagging DNA strands exist at a replication fork because ___________.A. the DNA polymerase can add new nucleotides onto either the 3' end or the 5' end B. the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5' end C. the two strands of DNA are parallel and DNA polymerase can only add new nucleotides onto a 3' D. end the two strands of DNA can be either parallel or antiparallel the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 3' end

Answers

Answer:

B. the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5' end

Explanation:

Deoxyribonucleic acid, known as DNA, is the genetic material of a cell, which must first undergo replication i.e produce two identical copies of itself, before a cell can divide. During replication, the double stranded DNA unwinds into a replication fork consisting of two single strands of DNA.

These single strands of DNA are called leading strand (runs from 3'-5') and lagging strand (runs from 5'-3'). These single strands that runs at opposite direction from one another exists at the replication fork because the two strands of DNA are antiparallel i.e. are opposite to one another, and DNA polymerase can only add new nucleotides onto a 5' end.

Leading and lagging DNA strands exist at a replication fork because the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5 'end.

A replication fork is the juncture between two strands of DNA when it is replicating itself.

In each of them (speaking of the homologous strands) the opposite chain is carried out to have the double genetic information when approaching cell division.

The direction in which the enzymes act is unique from 5 'to 3', this determines the template chain must have the direction 3'→ 5', so that the new chain in formation, complementary and antiparallel, has the direction 5 '→ 3' coinciding with the enzyme's working system.

The basic reaction that takes place in replication is a polymerization reaction, in a growing DNA chain a nucleotide is incorporated whose base is complementary to that of the template chain.

The DNA polymerases at the two ends of the free nucleotide to be incorporated use its phosphate group or 5 'end to add it to the growing chain.

Therefore, we can conclude that leading and lagging DNA strands exist at a replication fork because the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5 'end.

Explanation:

Carbon monoxide is often released from wildfires.

The air pollutant that gets released by natural wild fires is carbon monoxide. The correct option is D.

What is an air pollutant?

Air pollutants are natural and man-made airborne substances that are introduced into the environment in sufficient concentrations to have a discernible effect on air quality.

Large amounts of carbon dioxide, carbon monoxide, black carbon, brown carbon, and ozone precursors are discharged into the air by wildfires. These emissions have such a regional and even global impact on radiation, clouds, and climate.

This correct answer is the Abyssal Zone

The abyssal zone, which lies between 4,000 and 6,000 meters (13,000 and 20,000 feet) below the surface, is the deepest region of the ocean. So, option B is the answer.

The region of the ocean that lies beyond the continental shelf is commonly referred to as the oceanic zone. The sunshine zone, twilight zone, midnight zone, and abyssal zone are the four vertical zones that make up the open ocean.

Abyssal zone is characterized by high pressure, low temperatures, and very little light.

Kelp forest is found in shallower areas, often between 20 and 100 meters deep and Coral reefs are located in tropical, shallow waters.

A particular species of lizard can range in body color from dark brown to light brown. Body color influences how well an individual lizard can hide from predators. The more similar a lizard's body color is to the soil in its environment, the less likely it is to be seen by a predator The two graphs below represent two similarly-sized populations of lizards in similar environments that have medium-brown soil. Population 1 Population 2 Number of Individuals Number of individuals darker lighter darker lighter Body Color Body Color Suppose an environmental change that causes the soil color to become much different occurs in both environments. Which of the following is true? ​

Answers

Answer:

A- Population 1 is more likely to adapt and survive than population 2 because there is more variation related to body color in population 1.

Explanation:

In order for natural selection to occur, organisms within a population must have some genetic variation. That is, organisms within a population must have some traits that are different from one another. The more genetic variation that exists in a population, the better able the population is to handle environmental changes because it is more likely that at least some individuals will survive and reproduce.

The graphs show that population 1 exhibits a greater degree of genetic variation than population 2 in terms of body color. This means that if the soil in the environments where these populations live changes, it is more likely that some of the individuals in population 1 will survive and reproduce due to having advantageous body color in the new environment. Therefore, population 1 is more likely to adapt and survive than population 2 because there is more variation related to body color in population 1.
