Fetal hemoglobin (hemoglobin F) in health and disease

Williams–Beuren Syndrome — NEJM

During embryonic development, a cytoplasmic enzyme adds more A rsidues, allowing translation to occur
2) Activation or inactivation of one or more of the protein factors are required to initiate translation
3) Just after fertilization, translation is triggered by sudden activation of translation initiation factors(a burst of synthesis of proteins encoded by stored mRNA).
Lack nuclear membrane so transcription and translation can occur at the same time.
Protein Processing and Degradation
Transcription occurs before translation and after transcription mRNA must go through processing before moving to translation (ploy-a tail, methyl cap, and removal of introns).
Protein Processing
:
Polypeptide must be processed to yield functional protein molecules.

Kunstler “America does not want change, except from the cash register at Wal-Mart.”

Includes operator, promoter and genes.

RNA polymerase-
enzyme that aids in transforming DNA into RNA.

Repressor-
turns off the operon by binding to operator and blocking the attachment of RNA polymerase to promoter.

Regulatory Gene-
Produces repressors with its own controls and promoter that are located away from the operon.

Corepressor-
substance that works with a repressor to switch the operon off.

Inducer-
substance that inactivates the repressor to swith the operon on.
Prokaryotic and Eukaryotic Gene Expression
