How can a chromosome regulate transcription and increase it

In bacteria and eukaryotes, transcription is regulated by proteins which bind to the specific sites and modulate the activities. These sites are located on the chromosome, and they are a cluster of gene sequences known as operons. Operons are under the control of a single promoter, and can be induced/repressed or may work consistently all the time.  Main regulation of transcription occurs by rearrangement of histone proteins, which are located on the chromosome itself. These proteins may leave the desired gene sequence inaccessible for further operations.

Answer:

9.9 years

step-by-step explanation:

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
