What is DNA and RNA ?

Question

What is DNA and RNA ?

Answer 1

Both are genetic materials.

many species have gene, DNA(  Deoxyribonucleic acid), it codes for many proteins that body needs. It is usually double stranded in most animals.

RNA, Ribonucleic acid , assist DNA during  DNA and protein synthesis , the are  many types, the major ones are mRNA and tRNA; they are usually single stranded in animals

Answer 2

DNA STANDS FOR DIOXYRIBONUCLEICACID WHICH CARRIES THE GENETIC MATERIAL.

RNA STANDS FOR RIBONUCLEIC ACID WHICH CONTAINS PROTEIN.

Answer 3

DNA = deoxyribonucleic acid

RNA = ribonucleic acid

Both are polymers of nucleotides.  A nucleotide consists of three parts: 5-carbon sugar, phosphate group, nitrogenous base.  

In DNA, the sugar is deoxyribose.  

In RNA the sugar is ribose.  

In DNA the bases are thymine, adenine, cytosine, guanine.

In RNA the bases are uracil, adenine, cytosine, guanine.

In both, the polymer is made by covalent bonds between the sugar and phospate groups of neighboring nucleotides.  The bases sort of stick out from the molecule.  DNA is usually doublestranded so that two strands are held together by hydrogen bonds between the bases in the pairing rule A bonds with T and C bonds with G.

DNA is located in the nucleus of a eukaryotic cell.  RNA is primarily in the cytoplasm, but some forms of RNA can pass between the nucleus and cytoplasm.  DNA is the primary retainer of genetic information that is transferred from one generation to the next.  RNA has a number of functions including:

mRNA, which carries the genetic message from DNA for making proteins

tRNA, which brings amino acids to the ribosome during protein synthesis

rRNA, which, along with proteins, makes up ribosomes

Answer 4

DNA = deoxyribonucleic acid, a coiled up double stranded chain of a set sequence determined by your inheritance. there is 4 bases, adenine, thymine, guanine and cytosine.

DNA genes code for proteins, they tell a cell in your body what proteins to produce.

RNA = ribonucleic acid, a single stranded chain like DNA. two types include mRNA, messenger RNA, and tRNA, transfer RNA. messenger makes itself to a coppy of one of the DNA strands, and goes to a ribosome, where transfer RNA brings amino acids. the order at which the amino acids are joined depends on the order of the 4 base pairs. (in RNA thymine is replaced by uracil.) they are then linked by the ribosome to form a protein.
