Why are single-stranded binding proteins necessary for dna replication?
a. they provide the energy necessary to separate the two strands of dna.
b. they direct the primase where to lay down the primer.
c. none of the answer options is correct.
d. they direct where replication will start.
e. they prevent the two parental strands from coming together again.

The correct answer is e. They prevent the two parental strands from coming together again.

Explanation:

The replication of DNA requires not only DNA polymerase but also some other enzymes and proteins. To start DNA replication the double-strand DNA should be open up first which becomes possible by the action of DNA helicase.

This separated strand tends to anneal again so to prevent the reannealing of separated DNA strand single-strand-binding protein binds to these open strands. Therefore SSB protein stabilize the single stranded DNA so that the replication takes place fluently.

Therefore the correct answer is e. They prevent the two parental strands from coming together again.

explanation:

poof

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
