Using the model of a process above, identify the molecule that is shaded in purple and its function.
a)This is RNA polymerase performing transcription
b)This is a ribosome and is performing translation.
c)This is DNA polymerase and is performing replication.
d)This is an excision repair enzyme that repairs mutations.

a)This is RNA polymerase performing transcription

Explanation:

We can see that the purple molecule is attached to a DNA molecule, and is producing an mRNA molecule from a template strand. This is the process of transcription

The enzyme that carries out the synthesis of an mRNA molecule is RNA polymerase.

If the molecule was a ribosome performing translation, we would expect a polypeptide chain to be produced rather than an mRNA, and that the template molecule would be mRNA

If the molecule was DNA polymerase, it would synthesising a DNA strand not mRNA

If the molecule was a DNA repair enzyme, it would be correcting errors, not synthesising mRNA.

answer: all : )

explanation:

the answer would be knowledge about cars!
