Question

The gene products encoded by trans-acting elements perform their function by

A. associating with regulatory sequences distant from the gene from which they were transcribed. B. regulating the expression of the gene from which they were transcribed.
C. the association of nucleotides with the elongating RNA transcript.
D. physically associating with DNA polymerase.
E. regulating the activity of telomerase.

Answer 1

Ans. (A) associating with regulatory sequences distant from the gene from which they were transcribed.

Trans-acting elements is a transcription factor which recognise and bind to specific sequences in the cis-acting elements to initiate, enhance or suppress transcription. Trans-acting proteins that influence transcription are commonly referred to as transcription factors. The gene products encoded by the trans-acting elements perform their function by associating with regulatory sequences.
