What are the difference between DNA and RNA?
Answers
Explanation:
DNA (Deoxyribonucleic acid) RNA (Ribonucleic acid)
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
Answer:
1. DNA stands for Deoxyribonucleic Acid. <> RNA stands for Ribonucleic Acid.
2. DNA is a double-stranded molecule consisting of a long chain of nucleotides. <> RNA usually is a single-strand helix consisting of shorter chains of nucleotides.
3. DNA is self-replicating. <> RNA is synthesized from DNA on an as-needed basis.
4. DNA is found in the nucleus of a cell and in mitochondria. <> Depending on the type of RNA, this molecule is found in a cell’s nucleus, its cytoplasm, and its ribosome.
5. Functions: Long-term storage of genetic information; transmission of genetic information to make other cells and new organisms. <> Functions:Used to transfer the genetic code from the nucleus to the ribosomes to make proteins. RNA is used to transmit genetic information in some organisms and may have been the molecule used to store genetic blueprints in primitive organisms.
