(Biochemistry)biochemribonucleic acid; any of a group of nucleic acids, present in all living cells, that play an essential role in the synthesis of proteins. On hydrolysis they yield the pentose sugar ribose, the purine bases adenine and guanine, the pyrimidine bases cytosine and uracil, and ...
Nucleic acids—our buddies deoxyribonucleic acid, or DNA, and ribonucleic acid, or RNA—consist of long chains of nucleotides, which are monomers. (Sensing a pattern yet? Good. Biology is all about patterns.)Every nucleotide has three parts: A sugar A phosphate group A nitrogen-containing ...

Nucleic Acid In subject area: Medicine and Dentistry Nucleic acids are biopolymers comprised of nucleotide monomers that are composed of three moieties, a five-carbon sugar, a phosphate group, and a nitrogenous base. From: Encyclopedia of Cell Biology, 2016 ...
A structure for nucleic acid has already been proposed by Pauling and Corey. They kindly made their manuscript available to us in advance of publication. Their model consists of three inter-twined chains, with the phosphates near the fibre axis, and the bases on the outside. In our opinion,...

acid to the protein synthesis site. It is the base pairing between the tRNA and mRNA that allows for the correct amino acid to insert itself in the polypeptide chain. MicroRNAs are the smallest RNA molecules, and their role involves regulating gene expression by interfering with the expression ...
The two main types of nucleic acids are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Step 2: Structure of Nucleic AcidsNucleic acids are long chain polymers made up of smaller units called nucleotides. Each nucleotide consists of three components: a sugar (ribose in RNA and ...
