aivan3 [116]

Answer:

DNA ligase

Explanation:

DNA replication is an enzyme mediated, 3-step process during which the DNA molecule produces a copy of itself. The 3 steps involved are as follows;

  • initiation
  • elongation
  • termination

<em>Initiation </em>involves the unwinding of the double helix structure of the DNA using DNA helicase enzyme

<em>Elongation</em> involves binding of RNA primer to the DNA strands and addition of bases to the primer<em> </em>to elongate the new chains. Bases are added to the leading strand continuously while the lagging strand is replicated in short segments (okazaki segments).

<em>Termination</em> involves the unbinding of RNA primer and substitution of its bases by DNA bases. The Okazaki fragments are then joined together using the DNA ligase enzyme.

<em>The short, numerous segments of DNA observed in the mixture is the Okazaki fragments of the lagging strand. This is due to the absence of the enzyme involved in the joining of these fragments.</em>

Hence, the answer is DNA ligase.

Sergio [31]

Answer:

Here are the following options to complete the question

Which of the statements below is the best explanation of why athletes would need to monitor lactate levels?

A. During anaerobic respiration, lactate levels increase when muscles cells need more energy, however muscles cells eventually fatigue, thus athletes should modify their activities to increase aerobic respiration.

B. During aerobic respiration, muscles cells produce too much lactate which causes a rise in the pH of the muscle cells, thus athletes must consume increased amounts of sports drinks, high in electrolytes, to buffer the pH.

C. During anaerobic respiration, muscle cells receive too little oxygen and begin to convert lactate to pyruvate (pyruvic acid), thus athletes experience cramping and fatigue

D. During aerobic respiration, muscle cells cannot produce enough lactate to fuel muscle cell contractions and muscles begin to cramp, thus athletic performance suffers.

A is THE CORRECT ANSWER

A. During anaerobic respiration, lactate levels increase when muscles cells need more energy, however muscles cells eventually fatigue, thus athletes should modify their activities to increase aerobic respiration.

Explanation:

When the muscle cells undergoes anaerobic respiration, lactate are produced. Too much accumulation of lactate results in muscle fatigue. It is necessary for the athlete to prevent high accumulation by adjusting their exercise level

Stored in the laboratories at the centers for disease control and prevention and a Russian laboratory in Siberia are the only two place in which Smallpox virus remains.

<h3>What is smallpox?</h3>

Variola major or Variola minor are the two virus strains that cause the contagious sickness known as smallpox. The variola virus (VARV) agent is a member of the genus Orthopoxvirus. The World Health Organization confirmed the illness's universal eradication in 1980 after the last naturally occurring case was diagnosed in October 1977, making polio the only human disease to have achieved this feat.

Fever and vomiting were among the disease's earliest signs. This was followed by the development of mouth ulcers and a rash. The skin rash developed into the typical fluid-filled blisters with a dimple in the middle over a period of days. The scars were left after the lumps scabbed over and dropped off. People could contract the illness from contaminated things or from one another. Prevention is through the vaccine for smallpox.
