MCQ on lac and trp Operon

The lac operon and trp operon are genetic regulatory systems in prokaryotes. The lac operon controls the expression of genes responsible for lactose metabolism, allowing bacteria to use lactose as a carbon source. The trp operon regulates genes involved in tryptophan synthesis, ensuring its production when tryptophan is scarce. This […]

Chromosome Banding Techniques: Insights into Genetic Analysis

What is Chromosome Banding? Chromosome banding is an essential technique used in chromosome karyotyping to identify normal and abnormal chromosomes for clinical and research purposes. This technique involves staining the chromosomes to create distinctive patterns or bands on the chromosomes. The unique banding pattens helps to identify individual chromosomes and […]
