DNA polymerase has multiple mechanisms for editing and error correction, whereas the capacity for error correction in RNA polyme

rases seems to be quite limited. However, like a DNA mutation, an RNA polymerase error in transcription can cause production of a mutated protein. The limited error correction of RNA polymerase seems to be inconsistent with the potentially serious consequence of producing a protein with an altered amino acid sequence. Select reasons that explain why error correction is not as necessary in RNA polymerases as it is in DNA polymerases.
At least one of the reasons you have selected does not explain why RNA polymerases do not require rigorous error correction.
Transcription can produce many mRNA transcripts that then can be translated into many proteins.
If only one of these mRNAs contains an error, not all the copies of that particular protein will contain an error. Additionally, mRNAs and proteins have a finite lifetime and can be degraded while DNA persists from generation to generation. and translation.

Answer:

DNA polymerases are involved in the production of new DNA molecules while RNA polymerases are involved the transcription of DNA to mRNA.

Error correction is not necessary in RNA polymerase as compared to DNA polymerase because

1. The production of mRNA from DNA is for a period of time, that is, it is finite and when it is converted to proteins, it can be degraded. But the DNA replication is from generation to generation as it is inherited

2. The process of transcription is so fast. Thus, just few number of transcripts will have errors compared to the number produced.

Sedaia [141]

Answer: Here are three reasons if they don't help just tell me.

1. Changes in water temperature can affect the environments where fish, shellfish, and other marine species live. As climate change causes the oceans to become warmer year-round, populations of some species may adapt by shifting toward cooler areas. Oceans are becoming more acidic. 2.  Oceans are becoming more acidic. The acidity of seawater is increasing as a direct result of increasing carbon dioxide levels in the air from human activities, like burning fossil fuels. Concentrations of carbon dioxide are higher than in the last 800,000 years. Carbon dioxide dissolves in water, changing seawater chemistry and decreasing pH (making seawater more acidic). The ocean’s increased acidity results in thinner shells and more shellfish die as they become easier for predators to eat. 3.  More severe storms and precipitation can pollute coastal waters. Warmer oceans increase the amount of water that evaporates into the air. When more moisture-laden air moves over land or converges into a storm system, it can produce more intense precipitation—for example, heavier rainstorms. Heavy rain in coastal areas can lead to increases in runoff and flooding, impairing water quality as pollutants on land wash into water bodies. Some coastal areas, such as the Gulf of Mexico and the Chesapeake Bay, are already experiencing “dead zones” – areas where water is depleted of oxygen because of pollution from agricultural fertilizers, delivered by runoff. The phrase “dead zone” comes from the lack of life – including fish – in these waters.

What did Jean-Baptiste Lamarck believe about traits such as large muscles that are acquired during one's lifetime?
Kipish [7]

<span>The answer is they can be passed on to offspring.</span>

<span>
</span>

<span>In his theory, Lamarck proposed how species adapted to the changed environment by passing down acquired physical traits to the next generation. But, after Charles Darwin published his theory of evolution, Lamarck's theory was rejected. Now, it is known that acquired physical traits could not be inherited and epigenetics is a good proof for that.</span>
