Answer:
a. The operon is under positive control
a.) Loss of enzyme synthesis results from loss of regulatory R gene product which is regulated in the presence of Tis ophane for transcription. Absence of (Tis), transcription is positively controlled by regulatory Rprotein
b.) The proposed model reveals Tis / B complex prevents Tis enzymes from undergoing transcription through the RB operator by binding to the B region
the role of the R protein is
-decrease affinity of Tis / B complex to B region of RB
-bind to the R region on RB
- change the conformation of B region
- yield decreased affinity of Tis / B complex when R gene is lacking preventing transcription in the process
Effects of the RB mutations is that R protein will not bind to Tis / B complex to reduce transcription
Answer:
Barbed wire was invented and patented by Joseph Glidden in 1874 and had a major impact on the cattle industry of the Western U.S. Accustomed
Explanation:
Answer:
Generation of ATP in muscle cells.
Explanation:
Mitochonria is the power house of the cells, in this organelle of cell the biochemical process of respiration and generation of energy occurs. Energy produces in the form of ATP.
Mitochonrial DNA coded for specific protein complexes which are responsible for the process of electron transport chain and ATP synthase. If in the mitochondrial genes mutation occurs it will affect the production of ATP (energy) in muscle cells.
A substance that yields a cation plus the hydroxyl in water is base
