Question

Select the correct match:
A.T.H Morgan – transduction
B.Ribozyme – Nucleic acid
C.G. Mendel – Transformation
D.F2 cross recessive parent – dihybrid cross

Answer 1

Hint:We know that certain characters are passed on from parents to progeny. The process by which the progenies resemble their parents is called inheritance. Several scientists conducted experiments and found that DNA is the genetic material in most organisms.

Complete answer:
T.H Morgan was a scientist who conducted studies on fruit flies in-order to know about the scientific basis of variation produced as a result of sexual reproduction.
Variation is the degree by which the offsprings are different from their parents. He studied several sex-linked genes and gave the principles of linkage and recombination.
He said that the physical association of genes occurs between two genes and it leads to linkage. Non-parental genetic combination seen in the progenies is caused by a phenomenon called recombination.
Certain RNAs are capable of catalyzing chemical reactions by acting as an enzyme. These are called ribozymes. These are nucleic acids and function as an enzyme during protein synthesis.
G. Mendel is known as the father of genetics. He conducted studies on pea plants and proposed mendelian laws of inheritance. He conducted pollination experiments using true-breeding varieties of pea plants.
The process of crossing the dominant phenotype of the generation with the recessive parent is called a test cross. It is done to determine the genotype of the test organism.
Hence the correct option is B.

Note:We know that bacteriophages are viruses that infect bacterias. These viruses can act as a vector for carrying DNA into the bacteria. This phenomenon is called transduction. It was first described by scientist Joshua Lederberg.
