Two chains of DNA must run in ________ direction(s) and must be ________ in order to bond with each other.

Explanation / Answer
a. Inducer is allolactose. As when allolactose is available lac operon is induced.
Codons are triplet base sequences in the mRNA. it is similar to the sequence on the non-template strand.
Histone are not found in prokaryotes so prokaryotes is not related to histones.
They must run in antiparallel direction so they are complimentary to each other.
