Question

Select the correct statement
(a) Spliceosomes take part in translation
(b) Franklin Stahl coined the term “linkage”
(c) Transduction was discovered by S.Altman
(d) Punnett square was developed by British scientist

Answer 1

Hint: Genetics is the branch of science that deals with genes and heredity. Gregor Mendel is known as the father of genetics. British scientists have great contribution to genetics. It deals with DNA, chromosomes, and genes. The translation is the process of the formation of proteins. Punnett square is used to predict the genotypes.


Complete step by step solution:


A spliceosome is a unit that helps in the removal of introns i.e. non-coding regions of an mRNA and the production of mature mRNA with only coding sequences or exons. Thus, it is associated with transcription.

The term ‘Linkage’ was introduced by TH Morgan. He defined it as the tendency of genes to be inherited together. The closer they are located greater will be their tendency to be inherited together.

Transduction is the method of transfer of genetic material through viruses. It was first reported by Zinder and Lederberg in Salmonella in the year 1952.

The Punnett square is a grid used for determining the probable genetic and phenotypic composition of offspring in a particular generation. It is one of the most popular tools in genetics. It was developed by a British geneticist, Reginald Punnett.

Hence, the correct option is (d) Punnett square was developed by British scientist

Note: A Punnett square is used to make a monohybrid and Dihybrid cross. Incomplete dominance and co-dominance traits can be predicted by using the Punnett square. It also predicts the variations and probabilities that can come from cross-breeding. This includes predicting crossing plants, animals, and even humans with each other.
