Answer:

Step 1: Initiation - begins at the region of the DNA called the Promoter

Step 2: Elongation - the enzyme RNA polymerase reads the bases in the unwound unwound DNA strand and adds complimentary RNA nucleotides to create a new RNA strand.

Step 3: Termination - the process ends when the enzyme reaches a region of DNA called the termination or stop sequence which indicates the end of the transcription.

Explanation:

Transcription is the process in which RNA molecules are synthesized from the information stored in the DNA found in the nucleus. The region of the DNA that codes for genes is transcribed, or copied, into messenger RNA, known as mRNA, which then leaves the nucleus and enters into the cytoplasm where the information it carries is used to synthesize proteins.

Transcription occurs in three steps which are summarized below:

Step 1: Initiation - begins at the region of the DNA called the Promoter

Step 2: Elongation - the enzyme RNA polymerase reads the bases in the unwound DNA strand and adds complimentary RNA nucleotides to create a new RNA strand.

Step 3: Termination - the process ends when the enzyme reaches a region of DNA called the termination or stop sequence which indicates the end of the transcription.

Answer:

(E) seedless vascular plant

Explanation:

Seedless vascular plants, compared to some other kinds of plants, reproduce and disperse through unicellular spores instead of seed. They possess vascular tissues but do not possess seed or flower.

The life cycle of the seedless vascular plant is characterized by alternation between the diploid sporophyte and haploid gametophyte. The haploid gametophyte is small, but still independent while the diploid sporophyte is is large and long- lived, it is the dominant phase of the life cycle.

Examples of seedless vascular plants are horsetails and ferns
