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:
O4) All of the answer choices are correct.
Explanation:
Everyone that has teeth can be identified if they have a dental record. A forensic dentist can see what diet the person had, did they smoke, the age, the sex of the person and they are a source of DNA. We can examine the bite mark of the person in question and find out who they are. So teeth are very useful even when everything else on the remains is very badly damaged.
