... The main function of genes is to control the production of proteins. Proteins help determine the size, shape and other traits of organisms. Nitrogen bases form “rungs” of DNA ladder. The order of the nitrogen bases along a gene form a genetic code that specifies what type of protein will be pr ...

Gene Regulation
... Some genes are regulated (turned off and on) by repressor proteins While others use proteins that enhance the rate of transcription. Operons are generally not found in Eukaryotes. Gene regulation is controlled individually and have regulatory sequences that are much more complex that those of the la ...
