What does ribonucleic means in DNA

Open in App
Solution

Medical Definition of DNA. DNA:Deoxyribonucleic acid. One of two types of molecules that encode genetic information. (The other is RNA. ... DNA is a double-stranded molecule held together by weak hydrogen bonds between base pairs of nucleotides
Rinonucleic acid that is generally single-stranded , and composed of repeating nucleotide units of ribosesugaer, phosphategroup, and nitogenonit base

A nucleic acid refers to any of the group of complex compounds consisting of linear chains of monometric nucleotide. Each nucleotide is composed of phosporic acid , sugar and nitogenenous base . Nucleic acids may be in the form of deoxyribonucleic acid(DNA) or ribonucleic acid (RNA).

Ribonucleic acid, or RNA, is a single-stranded nucleic acid as opposed to the deoxyribonucleic acid, which is double-stranded. However, some viral RNAs and siRNA are double-stranded.

Structure: Ribonucleic acid (RNA) is a molecule consisting of a long linear chain of nucleotide. Each nucleotide unit is comprised of a sugar, phosphate group and a nitogenenous base. It differs from a DNA molecules in a way that the sugar backbone is a ribose(deoxyribose in DNA) .

Function: In some virus, RNA is the genetic material. For most organisms, RNAs are involved in:

  • Protein synthesis (e.g. mRNA, tRNA, rRNA etc.)
  • post-transcriptional modification or DNA replication (e.g. snRNA, snoRNA, etc.)
  • Gene regulation (e.g. miRNA, siRNA, tasiRNA, etc.)
