Overview

Genome technology studies how genetic material is mapped, sequenced, analysed, edited, and used to understand life processes and solve practical problems. The genome is the complete genetic information present in a cell. In prokaryotes, it includes DNA in the nucleoid and plasmid, while in eukaryote

Key Concepts

Genome is the complete genetic information

Genome is the complete genetic information present in a cell. In prokaryotes, it includes DNA in the nucleoid and plasmid. In eukaryotes, it includes

Genetic mapping estimates distances between loci

Genetic mapping estimates distances between loci using crossover analysis. Recombination frequency between loci is used to measure relative genetic di

Physical mapping identifies specific locations on

Physical mapping identifies specific locations on the genome using DNA-based features such as restriction sites, SSLP, and STS.

Restriction Fragment Length Polymorphism is

Restriction Fragment Length Polymorphism is a physical mapping technique in which restriction enzymes cut DNA at specific sequences and the fragments

Simple Sequence Length Polymorphism is based

Simple Sequence Length Polymorphism is based on repeat sequences such as microsatellites and minisatellites that vary in length.

Learning Objectives
