Dna replication occurs only in the 5' to 3 direction, meaning dna polymerase can only add new nucleotides to the 3' end of
the growing molecule. what forms as a direct result of the directionality of dna replication?
a) mutations on the lagging strand
b) okazaki fragments on the lagging strand
c) continuous replication on the lagging strand
d) excess hydrogen bonding on the leading strand

The correct answer is okazaki fragments on the lagging strand.

Explanation:

DNA replication occurs in the 5" to 3" direction.DNA replication occurs continuously in the leading strand which result in the formation of a  complete daughter DNA strand.

                     Whereas discontinuous replication occurs in the lagging strand resulitng in the formation of specific fragments.These fragment are known as okazaki fragments.

            DNA ligase then joins the okazaki fragmens to complete the synthesis of lagging strand.

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.
