Question

Select the correct statement.

• A. Spliceosome takes part in translation.
• B. Franklin Stahl coined the term “linkage”.
• C. Transduction was discovered S. Altman.
• D. Punnett square was developed by a British scientist.

Answer 1

The correct option is D

Punnett square was developed by a British scientist.

The correct option is D.

Explanation of the correct option:

1. Punnett square was created by Punnett, a British geneticist.
2. In breeding experiments, a Punnett square is primarily used to denote genotypes.
3. It can also be used to predict the most likely genotype of an organism's offspring.
4. By crossing the parental alleles across the Punnett square, the alleles of parental genes are written on the sides of the square-shaped Punnett square, which helps to determine the genotypes of offspring that determine whether they are dominant or recessive and whether they are homozygous or heterozygous.

Explanation of the incorrect options:

Option A:

1. A spliceosome is a structure in which splicing reactions take place.
2. Splicing is the process by which non-coding regions, known as introns, are removed from mRNA, leaving only exons, or coding regions, which are then translated into proteins.

Option B:

TH Morgan coined the term "linkage."

Option C:

Zinder and Lederberg discovered transduction in Salmonella in 1952.

Final answer: The correct statement is Punnett square was developed by a British scientist.
