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

Explanation:
Adenosine Diphosphate (ADP)
Answer:
DNA: ACT TTC GAT
mRNA: UGA AAG CUA
tRNA: ACU UUC GAU
AA: stop-lysine-leucine
Explanation:
mRNA is the complementary sequence of the DNA strand and tRNA is a complementary sequence of mRNA sequence. mRNA is a sequence of bases that is formed by encoding the DNA sequence in the complementary pattern during transcription.
tRNA is complementary of the mRNA code to produce the amino acid which is decided by the codon ( a three- base sequence of mRNA) what amino acid be present in what sequence.
Thus,
DNA: ACT TTC GAT
mRNA: UGA AAG CUA
tRNA: ACU UUC GAU
AA: stop-lysine-leucine (however, after the stop codon amino acid chain terminated in any protein)
