RNA, ribonucleic acids, are the molecules that direct the proteins of what to do. There are three types of RNA that conduct the direction of information sent by the DNA to the proteins: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). rRNA collaborates the commencement of the protein synthesis, and dictates when expressions of DNA should be “turned on or off”. tRNA transfers the amino acids, in cells, to proteins that are growing in the ribosomes. mRNA records information stored in the DNA and sent to the ribosomes.
RNA, ribonucleic acids, are made up of the same polynucleotides as DNA, except the deoxyribose sugar is replaced, in RNA, with ribose sugar. The bases are also the same, Guanine, Adenine, and Cytosine, but Thymine, which is found in DNA, is actually Uracil, which is in RNA. RNA is also shorter than DNA, is single stranded, whereas DNA is double stranded, and coils in the same helix form of DNA.
