Question 15

+2 marksOne or more correct options

Which of the following are true about feed-forward loop (FFL) motifs in transcriptional regulatory networks?

Select all that apply.

  1. A

    FFLs are simple sequences of gene interactions with no regulation involved.

  2. B

    FFLs can involve both positive and negative regulation, which helps control gene expression in a dynamic manner.

  3. C

    FFLs are mainly found in eukaryotic organisms and are not present in prokaryotes.

  4. D

    In an FFL, feedback can either increase (amplify) or decrease (attenuate) the gene expression signal.
