Answer:
B
Explanation:
A tiger strength and speed is not an example of selective breeding.
Answer:
C
Explanation:
A rainforest is humid, therefore, water uptake would likely not be an issue. However, rainforests have a huge number of trees, often these are very tall. These large trees might block out the sun from the smaller plants nearer the ground. This means they would struggle to properly photosynthesise, as they wouldn't have the necessary light energy.
Therefore, as a survival adaptation, it is likely that an allele that produced broader leaves for photosynthesis would be selected for in this population. Broader leaves would give a larger surface area for the plant to absorb light energy to perform photosynthesis.
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.
