Document Summary

Fad is involved with energy conservation via the electron transport chain: some redox enzymes participate in electron transport, nadh dehydrogenases, flavoproteins. Dna molecule to another, whether on the same molecule or another: found in all organisms and important for genetic variation, chromosomal gene arrangements and the operon. In e. coli, possible protein-coding genes account for 88% of the genome (~1% are genes encoding trnas and rrnas) In humans, only ~3% of the genome encodes proteins; lots of intervening. Termination of transcription: termination of rna synthesis is governed by a specific dna sequence. 12 or more subunits compared to 4 subunits for bacteria: archaea have only a single rna polymerase that closely resembles eukaryotic. Role of ribosomal rna in protein synthesis: ribosomal rna is important for protein synthesis, the proteins in the ribosome function to position key sequences appropriately in the ribosomal rnas, ex.
