Match the following:

Section A	Section B
a. DNA	1. Plant Virus
b. Avery	2. Semi-conservative
c. Stahl	3. Poly-nucleotyde
d. TMV	4. Transforming Principle

Solution(By Examveda Team)

a. DNA is a poly nucleotide. DNA is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.
b. Avery has given Transforming Principle. Oswald Avery's group showed that DNA was the "transforming principle." When isolated from one strain of bacteria, DNA was able to transform another strain and confer characteristics onto that second strain. c. Stahl has proposed an experiment on semi-conservative of replication. He demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template for the synthesis of a new, complementary strand.
d. TMV is a Plant virus, known as Tobacco mosaic virus. TMV is a single-stranded RNA virus that commonly infects Solanaceous plants, which is a plant family that includes many species such as petunias, tomatoes and tobacco.
