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.
Answer:
RNA molecules are made of nucleotides. (Ans. C)
Explanation:
RNA, which is also known as ribonucleic acid is found in cytoplasm of the cell, and synthesized in the nucleus. It is shorter, and a single stranded molecule. It is composed of one or more nucleotides which are linked together by phosphodiester bonds.
In RNA, the ribonucleotide contains pentose sugar ribose, four nitrogenous bases (A,U,C,G), and a phosphate group. RNA plays many types of role in cells, but mainly involved in the translation process, and it's regulation which is known as protein synthesis.
Answer:
“oxidoreductases.”
Hydrolysis.
Explanation:
Oxidoreductases are the enzymes that catalyze or speedup oxidation or reduction reactions. Reductases are the enzymes used for the speedup of reduction process whereas oxidases are the enzymes which speedup the process of oxidation. Hydrolysis is a process in which water is added to a substance for breaking of a single bond present between molecules of substrate.
