Jakob Hobbs · Answer 1

The answer is; transcription requires a specific combination of transcription factors

This allows the body to regulate a huge number of the gene with a small set of transcription factors. Using the analogy of combinatorial in mathematics, it is possible to have many combinations from a small set of numbers. This also applies in biology. Factors A and B in combination will regulate a different set of genes from factors A and C and factors B and C.

Kayden Dyer · Answer 2

The correct answer is: transcription requires a specific combination of transcription factors.

Combinatory control is part of regulatory mechanism in eukaryote and it represents control of transcription by a specific combination of factors. One certain factor in combination with different factors might regulate a distinct set of genes.
