sequence of three nucleotides of a tRNA molecule that pairs with the complement on an mRNA strand during protein synthesis
DNA sequence within a gene sequence that codes for a polypeptide sequence. Exons must be combined during mRNA processing.
DNA sequence within a gene sequence that does not code for a specific protein. Introns must be removed from the pre-mRNA during processing.
gene cluster that codes for enzymes that import and digest the sugar lactose in E. coli and other bacteria
RNA molecule made from a DNA template, contains the complementary gene sequence, that is, the sequence opposite to the DNA strand
collection of genes that are transcribed together and contain at least two regions of control, called a promoter and an operator
cell able to reproduce indefinitely and develop into other types of specialized cells
proteins expressed by the genome of an organism or a cell throughout its life or at a specified time under certain environmental conditions
process by which introns are removed from mRNA and exons are joined together following transcription
molecule that carries each amino acid to the strand of mRNA during translation of protein synthesis
assembly of amino acids into proteins in ribosomes through the reading of mRNA by tRNA and the ribosome
