Lecture 14 Flashcards
1
Q
How do TFs regulate gene expression?
A
TFs and RNA work together to transcribe DNA.
2
Q
What do non coding RNAs do?
A
Influence gene expression
3
Q
What is the function of micro RNAs
A
They are functional non-coding RNAs, regulate the expression of many mRNAs by binding to sequences in the 3’ untranslated region of protein coding genes. 1 miRNA can affect the expression of 100 genes
4
Q
Describe DNA methylation.
A
Gene inactivation that is reversible
