which of the following are methods of molecular biotechnology?
selective breeding
recombinant dna
hybridization
cloning
induced mutations
dna profiling

Recombinant DNA, Cloning and DNA profiling.

Explanation:

Molecular biotechnology deals with modification of nucleic acid (DNA) and proteins to produce the recombinant organisms for human benefits. It includes formation of recombinant DNA that carries gene from some other source, cloning of organisms to maintain the existing beneficial traits and DNA profiling to study the beneficial genes present in genome of a particular species.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
