Gene expression in prokaryotes is regulated at which stage?
A. Translation
B. Transcription
C. Post-transcriptional modification

Transcription

Explanation:

This occurs in three steps itself: initiation, elongation, and termination

Initiation (beginning)

- RNA polymers bind to a promoter on a gene

- DNA then unwinds to be "read" by an enzyme

- DNA now ready to make mRNA strand

Elongation (Second step)

- nucleotides are added to mRNA strand

- mRNA molecule is built after RNA polymers reads the DNA that unwound

- adenine (A) in DNA connects to a uracil (U) of RNA while connected to each other

Termination (End)

- RNA will cross a stop sequence in the gene (termination)

- mRNA done and disconnects or detaches from DNA

Hope this helps!

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.
