The processes of dna replication and rna transcription in e. coli are similar in some respects and different in others.
select the three statements below that describe both dna replication and rna transcription in e. coli.

a. the direction of enzyme movement on the template strand is 3' to 5'
b. the process requires a primer.
c. the mechanism of reaction is attack by the 5'oh group of the pentose on the a-phosphate of an incoming nucleoside triphosphate.
d. a specific region of the dna is recognized and bound by the polymerase.
e. the direction of polymerization is 5' to 3'
f. the process includes its own 3' to 5' exonuclease proofreading mechanism.

The three statements that describes both DNA replication and RN transcription in E.coli are listed below.

Explanation:

C The mechanism of reaction is attack by the 5" OH group of the pentose on the alpha phosphate of an incoming nucleoside triphosphate.

A The direction of enzyme movement on the template strand is 3"→ 5.

E  The direction of polymerization is 5"→3"  

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
