Answer:
You have not consumed lactose from dairy recently
Explanation:
According to the diagram, there is a represssor element in the regulatory region of the operon. This repressor is blocking the RNA polymerase, that is bound to its promoter region upstream of the genes, from transcription. The repressor is mostly the lac repressor that switches of the operon in the absence of lactose.
Simple but very simple question. Cellulose.
Answer:
a) All Walnut , Genotype - RrPp
b) Walnut : Rose: Single
1:1:2
Explanation:
Phenotype and their Genotype -
Walnut comb - R_ P_
Rose Comb - R_ pp
Pea Comb - rr P_
Single Comb - rr pp
a) RR PP * rr pp
All progenies will have genotype RrPp (Walnut Comb)
b) Rr Pp * rr pp
RrPp (4), Rrpp (4), rrpp (8)
Walnut : Rose: Single
1:1:2

Answer:
The provided events can be classified as:
Initiation
- In prokaryotes, the Shine-Dalgarno sequence pairs with rRNA.
- In E. coli, mRNA binds to the 30S ribosomal subunit.
Elongation
- In E. coli, EF-Tu delivers an aminoacyl-tRNA to the ribosome
- Initiator tRNA enters the P site.
- In E. coli, EF-Tu hydrolyzes.
- Translocation occurs
Termination
- The ribosome has mRNA, an empty A site, and deacylated tRNA in the P site
Translation is the process by which polypeptide chain is synthesized based on the codon sequence of the mRNA (messenger ribonucleic acid).
It is divided into three stages:
Initiation: The small and large sub-units of the ribosome get assembled around the initiation codon. It forms three sites (A, P, and E site) for interaction tRNA and mRNA.
Elongation: Specific charged-tRNA enters from A site and transfers its amino acid to the growing polypeptide chain in P site. Uncharged tRNA exit from the E site. Ribosome moves or translocates to the next codon.
Termination: As soon as ribosome reaches the termination codon, it releases the newly synthesized polypeptide chain.
