what is degree of freedom

1- Degrees of freedom represent the number of ways in which the observed outcome categories are free to vary.

2- Degree of freedom refers to the minimum number of logically independent values, which are values that have the freedom to vary in the data sample.

3.Degrees of freedom represent the number of ways in which the observed outcome categories are restrict to vary.

Repression of the GAL1 gene in yeast by Mig1, in the presence of glucose follows those steps;

I- Deacetylation of local nucleosomes

II-Recruiting the Tup1 repressing complex

III- Mig1 represses expression of GAL1

IV- Mig1 binds a site between the UASG and the GAL1 promoter

In eukaryotes, transcriptional regulators are not typically controlled at the level of DNA binding (although there are exceptions). Regulators are instead usually controlled in one of the following two basic ways.

I. Unmasking an Activating Region

II. Transport into and out of the Nucleus

III. Mediated through proteolysis of an inhibitor or tethering region or by allosteric changes.

IV. Also is itself (or recruits) a deacetylase,
