Document Summary
Transcription i and ii: molecular definition of a gene. Recall the flow of information in the cell . A lot of underlying mechanisms are similar in eubacteria transcription from. We can define genes functionally, based on biochemical properties, structurally (promoter sequences, coding regions, noncoding regions, terminator sequences, etc. ), or in the context of genetics and heredity (allelic). The entire nucleic acid sequences (usually dna) that is necessary for the synthesis of a protein (and its variants) or rna. In other words, genes are segments of dna that are transcribed into rna, whether it"s translated later or not. Remember, there are two types of genes that, when transcribed, . Genes are under the control of promoter sequences, generally upstream of the gene itself. When the cell needs the gene, the promoter will cause transcription of lots of rna which generally goes on to cause translation for increased protein. Different genes generally under control of different promoters.
