Leave a Comment / Human Growth and Development (MANE 002) /

Introduction Human growth is influenced by both genetic and environmental factors. While genetics determines the potential for growth, the environment plays a crucial role in realizing that potential. Environmental factors can either promote healthy growth or hinder it, especially during sensitive periods like infancy, childhood, and adolescence. Definition of Environmental Factors Environmental factors refer to […]

Write short notes on any two of the following: a). Polymerase Chain Reaction (PCR) b). Hap Map Project c). Ethical principles in genetic research d). Phenylketonuria (PKU)

Leave a Comment / Human Genetics (MANE-001) /

a) Polymerase Chain Reaction (PCR) Polymerase Chain Reaction (PCR) is a laboratory technique used to make multiple copies of a specific segment of DNA. It was developed by Kary Mullis in 1983 and revolutionized genetic research. Steps in PCR: Denaturation: DNA is heated to separate the strands. Annealing: Short primers bind to specific sequences. Extension:

Discuss the concept of gene in the light of Beadle and Tatum’s work.

Leave a Comment / Human Genetics (MANE-001) /

Introduction The concept of the gene has evolved over time with contributions from various scientists. One of the most influential experiments in understanding the gene’s function was conducted by George Beadle and Edward Tatum in the 1940s. Their work laid the foundation for molecular genetics and introduced the famous concept: “one gene, one enzyme hypothesis.”
