the triplet of bases on the transfer RNA

the triplet of bases on the messenger RNA

an enormous molecule made of repeating units called nucleotides. In the nucleus, DNA is always a double molecule. Each DNA has a backbone of phosphate and sugar molecules with projecting nitrogen bases.

a basic part of DNA and RNA. there are four nitrogen bases present in DNA: adenine, thymine, guanine and cytosine. The same four are in RNA with thymine being substituted by uracil.

the basic unit of the nucleic acid molecule composed of a phosphate group, a five carbon sugar and a nitrogen base.

a large molecule made up of hundreds of aminoacids.

a molecule made of nucleotides. There are three classes of RNA: Messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA)

DNA produces RNA which produces protein.

the formation of mRNA from a strand of DNA in the nucleus.

the formation of protein at the ribosomes using the information on mRNA and amino acids attached to tRNA.
