Which of the following procedures would produce rflps? a) incubating a mixture of single-stranded dna from two closely related species b) incubating dna nucleotides with dna polymerase c) incubating dna with restriction enzymes d) incubating rna with dna nucleotides and reverse transcriptase e) incubating dna fragments with êºsticky endsêº with ligase

Restriction fragment length polymorphism (RFLP) could be produced by incubating DNA nucleotides with restriction enzymes.

i'd say that the moon rock is about 2.2 billion years old.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
