explain the structure, function and types of RNA
Answers
An RNA nucleotide has three main components - a nitrogenous base, a ribose sugar, and a phosphate group.
∙ The ribose sugar and the phosphates form the backbone of a polynucleotide chain with nitrogenous bases linked to sugar moiety and projecting from the backbone.
∙ Two types of nitrogenous bases are present i.e. Purines (Adenine and Guanine) and Pyrimidines (Cytosine and Uracil).
∙ RNA helps in transforming information present in the form of DNA into protein.
There are 3 types of RNA:
1. mRNA (messenger RNA) - It serves as a template for protein synthesis. DNA is transcribed to form an mRNA, which in turn is translated to form a protein.
2. tRNA (transfer RNA) - It brings amino acids during translation and reads the genetic cod
Answer:
The primary function of RNA is to create proteins via translation. RNA carries genetic information that is translated by ribosomes into various proteins necessary for cellular processes. mRNA, rRNA, and tRNA are the three main types of RNA involved in protein synthesis.
