What are DNA and RNA ? In cells
Answers
Answer:
DNA and RNAA nucleotide is made up of three components: a nitrogenous base, a pentose sugar, and one or more phosphate groups. Carbon residues in the pentose are numbered 1′ through 5′ (the prime distinguishes these residues from those in the base, which are numbered without using a prime notation). The base is attached to the 1′ position of the ribose, and the phosphate is attached to the 5′ position. When a polynucleotide is formed, the 5′ phosphate of the incoming nucleotide attaches to the 3′ hydroxyl group at the end of the growing chain. Two types of pentose are found in nucleotides, deoxyribose (found in DNA) and ribose (found in RNA). Deoxyribose is similar in structure to ribose, but it has an H instead of an OH at the 2′ position. Bases can be divided into two categories: purines and pyrimidines. Purines have a double ring structure, and pyrimidines have a single ring.
Definition
It is a long polymer. It has a deoxyribose and phosphate backbone having four distinct bases: thymine, adenine, cytosine, and guanine. Is a polymer with a ribose and phosphate backbone with four varying bases: uracil, cytosine, adenine, and guanine.
Location
It is located in the nucleus of a cell and in the mitochondria. It is found in the cytoplasm, nucleus, and in the ribosome.
Sugar portion
It has 2-deoxyribose. It has Ribose.
Function
DNA is functional is the transmission of genetic information. It forms as a media for long-term storage. RNA is functional is the transmission of the genetic code that is necessary for the protein creation from the nucleus to the ribosome.
Predominant Structure
The DNA is a double-stranded molecule that has a long chain of nucleotides. The RNA is a single-stranded molecule which has a shorter chain of nucleotides.
Propagation
DNA replicates on its own, it is self-replicating. RNA does not replicate on its own. It is synthesized from DNA when required.
Nitrogenous Bases and Pairing
The base pairing is as follows: GC(Guanine pairs with Cytosine) A-T(Adenine pairs with Thymine). The base pairing is as follows: GC(Guanine pairs with Cytosine) A-U(Adenine pairs with Uracil).
