COMPARISON BETWEEN DNA AND RNA
DNA and RNA are nucleic acids. Nucleic acids consists of minor particles called nucleotides. In DNA and RNA, these nucleotides contain four nucleobases —nitrogenous bases or bases — two purine and two pyrimidine bases.
DNA is found in the center of a cell (atomic DNA). It has two nucleotide strands which comprise of its phosphate gathering, five-carbon sugar (the steady 2-deoxyribose), and four nitrogen-containing nucleobases: adenine, thymine, cytosine, and guanine.
Amid interpretation, RNA, a solitary stranded, straight atom, is framed. It is corresponding to DNA, completing the errands that DNA records for it to do. Like DNA, RNA is made out of its phosphate gathering, five-carbon sugar (the less steady ribose), and four nitrogen-containing nucleobases: adenine, uracil (not thymine), guanine, and cytosine.
In the two atoms, the nucleobases are appended to their sugar-phosphate spine. Each nucleobase on a nucleotide strand of DNA appends to its accomplice nucleobase on a second strand: adenine connects to thymine, and cytosine connects to guanine. This connecting makes DNA’s two strands bend and twist around each other, framing an assortment of shapes, for example, the celebrated twofold helix (DNA’s “casual” frame), circles, and supercoils.
In RNA, adenine and uracil (not thymine) connect together, while cytosine still connects to guanine. As a solitary stranded particle, RNA overlap in on itself to connect up its nucleobases, however not all move toward becoming joined forces. These resulting three-dimensional shapes, the most well-known of which is the clip circle, help figure out what part the RNA particle is to play — as courier RNA (mRNA), exchange RNA (tRNA), or ribosomal RNA (rRNA).
DNA provides living organisms with guidelines—genetic information in chromosomal DNA—that help determine the nature of an organism’s biology, how it will look and function, based on information passed down from former generations through reproduction. The slow, steady changes found in DNA over time, known as mutations, which can be destructive, neutral, or beneficial to an organism, are at the core of the theory of evolution.
Genes are found in small segments of long DNA strands; humans have around 19,000 genes. The detailed instructions found in genes—determined by how nucleobases in DNA are ordered—are responsible for both the big and small differences between different living organisms and even among similar living organisms. The genetic information in DNA is what makes plants look like plants, dogs look like dogs, and humans look like humans; it is also what prevents different species from producing offspring (their DNA will not match up to form new, healthy life). Genetic DNA is what causes some people to have curly, black hair and others to have straight, blond hair, and what makes identical twins look so similar.
RNA has several different functions that, though all interconnected, vary slightly depending on the type. There are three main types of RNA:
Messenger RNA (mRNA) : -transcribes genetic information from the DNA found in a cell’s nucleus, and then carries this information to the cell’s cytoplasm and ribosome.
