a. the RNA polymerase undergoes abortive initiation prior to promoter clearance
Explanation:
In eukaryotes the 3' end of the mRNA is polyadenylated to protect the mRNA from degradation.
In eukaryotes, a modified guanine cap is added to the 5' end of the mRNAd to protects the transcript from being broken down.
Most bacterial RNA transcripts do not undergo splicing.
The nucleosome is the basic unit of chromatin repeat in eukaryotes.

The answer to your question is below
Explanation:
Let's describe the phases of mitosis
Interphase is the process before cell division starts. This stage is about 90% of the cell cycle. Letter E.
Prophase: in this phase, chromatin condensates into chromosomes and the nuclear envelope vanishes. Letter B.
Metaphase: the chromosomes align in the equator. Letter F.
Anaphase. the chromosomes separate and move to the cellular poles. Letter C.
Telophase. The chromosomes are covered by a new nuclear membrane. Letter D.
Cytokinesis. is the process when the two new cells are formed. Letter A.
A species is a group of organisms capable of mating and producing
offspring. This is another way of saying that a species is
reproductively isolated.
