Question

ion phase RNA Transcription i by the match the During transcription, RNA is transcribed or copied from a small segment of DNA containing a single gene or part of a single gene. The DNA strand that the RNA Is transcribed from, is the template strand, The non-template strand that is not being copied is referred to as the coding strand. There are three phases in RNA transcription: initiation, elongation, and termination anti-cods ithes oe During the initiation phase, the promotor region indicates the start of t will attach to the promotor region. The ranscription. The RNA strand will be transcribed from a . During the elongation phase, the to direction. equent growing stand. will continue to add RNA nucleotides to the . if the DNA strand reads 3' AGGTTAC 5', the transcribed RNA strand will be5 . During the termination phase, the RNA polymerase encounters the terminator region of . The type of RNA that is produced during transcription is DNA that indicates the end of transcription. .

Explanation / Answer

Solution 1.

RNA polymerase as a holoenzyme binds at promoter and starts the initiation reaction by forming a closed binary complex.

The new RNA strand will be transcribed in 5' to 3' direction.

Solution 2.

RNA polymerase continues to add RNA nucleotide to growing chain during elongation step.

Solution 3.

3' AGGTTAC 5'

5' UCCAAUG 3'

Adenine will be transcribed into Uracil

Guanine will be transcribed into cytosine

Thymine will be transcribed into adenine

Solution 4.

Type of RNA that produced after transcription is messenger RNA
