In this essay we will discuss about: Meaning of RNA 2.

DNA & RNA Summary -

Features of RNA 3. A nucleic acid that carries the genetic message from DNA essay on dna and rna ribosomes and is involved in the process of protein synthesis is referred to as RNA [ribose nucleic acid]. Ribonucleic acid is one of the two types of nucleic acids found in all cells. The other is deoxyribonucleic acid DNA. Ribouncleic acid RNA and rna a nucleic acid polymer consisting of continue reading monomers that acts as a messenger between DNA and ribosomes and is also responsible for making essay on dna and rna out of amino acids.

In eukaryotes, RNA is found both in nucleus and cytoplasm.

DNA & RNA Summary

In the nucleus it is a component of chromosome, whereas in cytoplasm it is essay on dna and rna in ribosomes. In prokaryotes, it is found in the cytoplasm. After synthesis it moves from nucleus to cytoplasm. Thus, RNA essay on dna and rna does not have self-duplication property. It consists up to 12, nucleotides whereas DNA consists up to 4.

In most of the organisms, the usual function of Essay on dna and rna is transfer of /descriptive-essay-my-most-comfortable-place.html message from nucleus to the cytoplasm and synthesis of protein in ribosomes. And rna some viruses, RNA acts as the genetic material and essay on dna and rna the gene action.

Mostly the RNA molecule is single stranded in both eukaryotes and prokaryotes. However, in some viruses RNA is double stranded.

The essay on dna and rna stranded RNA is found in Rio virus in animals and wound tumour virus in plants. Essay dna single strand of RNA is folded upon itself cither entirely or in some regions. Most of the base in the folded region are complementary and are click by hydrogen bonds.

However, and rna the unfolded regions the bases do not have complements. Essay on dna and rna a result, the purine and pyrimidine ratio is not equal in RNA molecule. The RNA is composed of and rna sugar, nitrogenous bases and phosphate group.

The nitrogenous base in RNA are: The And rna molecule is a polymer which is composed of several thousand pairs of nucleotide monomers.

Nucleotides are also known as nitrogenous bases or DNA bases. Nitrogenous base are of essay on dna and rna types, viz. The features of pyrimidines and purines are given below.

Thus, in RNA there are four different types of nitrogenous bases, viz.

In DNA, the pyrimidine base uracil essay on dna and rna the following article replaced by thymine. The purine and pyrimidine bases always pair in a definite fashion. Adenine will always pair with uracil and essay on dna and rna with cytosine. Adenine essay dna thymine are joined by double hydrogen bonds while guanine essay on dna and rna cytosine are joined by triple hydrogen bonds.

Both are pentose sugar having five carbon atoms. The four carbon atoms are inside the ring and the fifth one is with CH 2 group.

This has four OH groups on 1, 2, 3 and 5 carbon positions. Hydrogen atoms are attached to carbon atoms one to four. Essay on dna and rna phosphate molecule is arranged in an alternate manner to ribose sugar. Thus there is ribose sugar on both sides of phosphate. The phosphate is joined with carbon atom 3 of ribose at one side and with carbon atom 5 of ribose on the other side.

In RNA, nucleoside is a combination of ribose sugar and nucleotide is a combination of nucleoside and phosphate. Thus, a nucleotide is essay on dna and rna nucleoside with one or more phosphate groups covalently attached to it. Nucleosides differ from nucleotides in that they lack phosphate groups.
