n. the process in which the information contained in the *genetic code is transferred from DNA to RNA: the first step in the manufacture of proteins in cells. See messenger RNA; translation.
n. absence of an organ, usually due to total failure of its development in the embryo. Dental agenesis (also known as *hypodontia) is the most common developmental anomaly in humans and may be caused by genetic defects in codes for transcription factors, proteins, and fibroblast growth factors.... agenesis
the code in which genetic information is carried by *DNA and *messenger RNA. This information determines the sequence of amino acids in every protein and thereby controls the nature of all proteins made by the cell. The genetic code is expressed by the sequence of *nucleotide bases in the nucleic acid molecule, a unit of three consecutive bases (a codon) coding for each amino acid. The code is translated into protein at the ribosomes (see transcription; translation). Any changes in the genetic code result in the insertion of incorrect amino acids in a protein chain, giving a *mutation.... genetic code
