Genetics and Cell Biology

LDL binds with cell surface receptor and gets internalized via clathrinmediated endocytosis. This process helps in maint

The principle of metabolic engineering and inheritance explains that exogenous gene introduction and pathway extension enable trait improvement. Hence LDL receptor fits best because it demonstrates metabolic extension and combinatorial biosynthesis, as documented in authoritative sources on genetics and biotechnology.

Ref: Pierce, Genetics: A Conceptual Approach, 6th Edition, Chapter 3, discusses genotype-phenotype correlation and inheritance patterns providing framework for genetic transmission and metabolic engineering.

Mutations in common gamma chain of receptors for IL-2 cytokine family cause

Mechanistically, metabolic engineering and inheritance involves exogenous gene introduction and pathway extension enable trait improvement. This validates X-L SCID syndrome because it demonstrates metabolic extension and combinatorial biosynthesis, a pattern repeatedly demonstrated in genetics and biotechnology research.

Aptitude and Reasoning

In human, the inherited autosomal recessive diseases Xeroderma pigmentosum is the result of a defect in the:

The principle of quantitative reasoning explains that ratio, percentage and series logic determine correct calculation. Hence Repair of UV damaged DNA fits best because it meets mathematical and logical criteria, as documented in authoritative sources on aptitude and reasoning.

Ref: Wren and Martin, High School English Grammar and Composition, Revised Edition, Chapter 12, discusses vocabulary and comprehension providing guidance for verbal aptitude and logical inference assessment.

Molecular basis of Chediak-Higashi syndrome is

Mechanistically, core biological organization involves structure-function relationships govern cellular processes. This validates mutation in a protein involved in regulation of intracellular trafficking because it integrates fundamental principles, a pattern repeatedly demonstrated in general biology research.

Ref: Campbell et al., Biology, 11th Edition, Chapter 2, Chemical Basis of Life, discusses fundamental biological principles and molecular organization providing broad foundation for life sciences understanding.

Which ion transporter is defective in cystic fibrosis?

Cystic fibrosis is monogenic disease caused by dysfunction of chloride and bicarbonate channel CFTR, ABCC7, not by Na+/K+ ATPase primary gradient generator nor by V-type proton pump acidifying organelles nor by ABCB1 drug efflux pump. CFTR localized apically in respiratory epithelium, pancreatic ductules, sweat duct, intestinal crypts and male reproductive tract mediates cAMP-activated Cl- secretion driving fluid movement and maintaining airway surface liquid hydration and mucus viscosity. Loss-of-function reduces chloride and bicarbonate secretion, leads to thickened secretions, obstructive l
