Steps of dna replication (basic steps)

Helicase unwinds dna.

Single stranded binding proteins makes sure they don’t come back together.

Topoisomerase keeps the dna from supercoiling.

Primase makes dna primers for both strands.

Dna polymerase builds the new strand in the opposite direction of the original template strand.(example: template strand is in 3’ to 5’ direction and the new strand is in 5’ to 3’ direction)

The Lagging strand pieces are sealed together by ligase.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.

explanation:

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
