Explanation:
<h2>
Option (B) is Right Answer</h2>
Explanation:
(B) chromatids are attached to one another
- <em>The linkage between the sister chromatids </em>is particularly critical at centromeres because it ensures right <em>microtubule connection to the kinetochores </em>
- In eukaryotes, a centromere is a district of DNA that is responsible for the development of the imitated chromosomes into the<em> two daughter cells during mitosis and meiosis</em>
- There is one centromere on every <em>chromosome and centromeres are responsible for two major functions</em>
- In eukaryotes, a centromere is a district of DNA that is responsible for the development of the imitated chromosomes into the <em>two daughter cells during mitosis and meiosis</em>
Answer:
The expression of the mRNA decreases.
Explanation:
The RNAi binds to some proteins forming a silencing complex. This complex binds to the target mRNA (of which the RNAi is complementary) and cleaves it (cuts it). The cell will detect the generated fragments of mRNA , recognize they are aberrant and will thus degrade them.
All in all, this mechanism silences (reduces) the expression of the mRNA, because it will be degraded instead of translated into protein.
