A mutation occurs in a gene, resulting in it being expressed at the wrong time during development. Where is the mutation most likely to be found?
a) In the transcription start site (TSS)
b) In a TF binding site in the cis-regulatory region
c) In the coding sequence
d) In the 5' UTR
Write a short essay describing which types of trans-acting proteins bindto which type of cis-regulatory element, and how these interactionsinfluence transcription initiation ?
Why is regulating transcription the main way that cells control gene expression?
A.
Because transcription is the last step in gene expression, stopping here ensures that the cell has a stockpile of proteins to prepare them from all unexpected environmental changes.
B.
Because transcription involves interactions with DNA, preventing transcription reduces the changes of mutation in the cell’s genome.
C.
Because transcription is the first step in gene expression, stopping at transcription reduces the amount of energy and resources used by producing unnecessary gene products.
D.
Because transcription is the shortest step in gene expression, preventing transcription has little effect on the rate of protein production.
