True or false? regulatory and basal transcription factors regulate transcription by binding to the promoter.

False

Explanation:

Transcription factors are molecules (usually proteins) that bind to DNA and regulate the transcription of the gene. So, they are gene expression regulators.

General or basal transcription factors are important for the initiation of transcription. Some of them don't bind to the DNA, but interact with RNA polymerase. Basal transcription factors are part of the transcription preinitiation complex . The whole complex binds to promoter.

Other regulatory factors such as activators and repressors bind to specific DNA sequencies. Activators bind to enhaceres in order to increase gene expression (turn on), while repressors bind to silencers and negatively regulate transcription (turn off).

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
