Answer: (TFIID) TBP-> TFIIB IIA--> TFIIF RNA POL II
Explanation:
Remember that in eukaryotic organisms, transcription and processing are coupled processes. There are 3 different types of Rna pol. In the case of RNA pol II transcribes genes that encode proteins (mRNA synthesis). Transcription factors are involved, for example: TFIID, TBPs, TAF (recognizes TATA promoter center, regulatory functions), TFIIA (stabilizes TBP union, antirepressant function), TFIIB (RNA Pol II starting point selection).
Increases genetic variation, which in and of itself has extreme benefits such as protection against disease, capability to evolve, etc
Answer:
The correct answer will be option-B
Explanation:
Meiosis is a way of cell division used by the organism to produce a large number of cells from a few parent cells. This is used to make the gametes of the body.
Meiosis produces four daughter cells from a single parent cell in two stages that is meiosis I and II. Each stage proceeds in four phases- prophase, metaphase, anaphase and telophase.
The reduction division of the chromosomes or the ploidy number takes place during anaphase I of meiosis I and not prophase I which is the initial phase of the division. Therefore, during prophase I the chromosome number of the cell remains the same.
Thus, Option-B is the correct answer.
