Question

A researcher documents a new and rare disease in genetics students that leads to spontaneous brain melting during exams. Through much work and many brains, they identify a specific mutation in a gene responsible for this disease. This is an example of: Pleiotropy Reverse Genetics Mutagenic Screen Forward Genetics The enzyme required for DNA polymerases to begin elongation is Helicase Initiator protein Gyrase Primase a pleiotropic mutation has little effect in the affected individual exists only in metabolic pathways must occur in coding DNA results in widespread symptoms

Explanation / Answer

7.option B- reverse genetics is correct option. Because studying the gene structure from its phenotype is called reverse genetics.

8.Option.A-Heliase is answer. Because without Helicase unwounded -DNA formation will not happen, so initiation will not occur. Hence Helicase first important enzyme.

9.Option D -Results in widespread symptoms is correct option.
