Answer:
b. unable to terminate transcription of some genes.
Explanation:
Rho protein is a polypeptide with 419 residues and is found in prokaryotic cells such as bacteria.
Termination refers to the point where a signal is made for transcription to stop. This usually occurs when a part of the DNA known as the terminator is transcribed. The transcription of this part halts then transcription process.
A lack of the rho protein means transcription of some genes won’t be able to be stopped( terminated).
Answer:
The importance to goblet cells and other glandular epithelia are to secrete mucus in order to protect the mucous membranes where they are found.
Mendel wants to control the pollination of his pea plants because traits were not blended but they remain separate in the subsequent generations and also it is contrary to scientific opinion during his time
<u>Explanation:</u>
- Mainly, he wants to control because they were against the scientific opinion during his time.
- Mendel takes a pea plant for his experiment because it can be easily observable.
- Pea plant has seven traits and it can be pollinated by both the ways. One is self-pollination and the other is cross-pollination.
- Mendel did not know about the genes but he speculates the factors of formation in the traits.
- Mendel produces three laws, the law of dominance, the law of segregation, the law of independent assortment.
