cellular control Flashcards
homeobox gene
are regulatory genes that code for the development of a body plan.
why are homeobox genes similar across all organis,s
genes are very important,changes would alter the body plan affecting many other genes
regulatory gene and structural gene
regulatory gene codes for a repressor protein structural gene codes for an enzyme. Regulatory gene controls expression of structural gene
post transcriptional level
primary mRNA modified
introns removed to make mature mRNA
alternative splicing produces different versions of mRNA
why is galactose used as a respiratory substrate
soluble so can move within cells
can form hydrogen bonds with water
bonds contain energy
post translational level
camp is activated by the binding of a hormone to a receptor.Camp activates other proteins
transcription factors
help rna polymerase bind(activators)
or prevent in from binding (repressors)
