Question

1.

Transcription of an actin gene takes place in the:

a. Nucleus
b. Golgi apparatus and rough endoplasmic reticulum (ER)

c. Lysosome
d. Mitochondrion
e. Smooth endoplasmic reticulum

2.

The enzyme that is responsible for the synthesis of RNA from a DNA template is called:

a. DNA polymerase (POL I, II or III)

b. RNA polymerase (POL I, II, or III)

c. ATPase
d. Topoisomerase

e. Reverse transcriptase

Answer 1

1.Transcription of the actin gene takes place in the nucleus. Transcription is the process where DNA template is used to generate RNA molecules. Transcription process takes place in the nucleus where the DNA The genetic material is present.

2. The enzyme that is responsible for the synthesis of RNA from DNA is RNA polymerase. RNA polymerase I synthesizes ribosomal RNA in the cell. rRNA is the largest portion of RNAs produced in the cell. RNA polymerase II synthesizers mRNA which in turn form proteins. RNA polymerase III is used to synthesise mainly tRNA.
