Write short notes on the following:
(i) Bioinformatics
(ii) Amniocentesis
Show Hint
Remember: Bioinformatics combines biology and computer science to analyze DNA, proteins, and genomes.
Solution and Explanation
Bioinformatics is an interdisciplinary field that uses computational tools to analyze and interpret biological data, such as DNA sequences and protein structures. Bioinformatics plays a crucial role in genome sequencing, evolutionary biology, and personalized medicine by providing insights into genetic data through software applications.
Amniocentesis is a prenatal diagnostic technique used to detect genetic disorders in the fetus by analyzing amniotic fluid.A small sample of amniotic fluid is extracted from the uterus using a needle to analyze fetal cells for chromosomal abnormalities such as Down’s syndrome.
Top Questions on Biotechnology
The vector, shown in the figure, has promoter and RBS sequences in the 300 bp region between the restriction sites for enzymes X and Y. There are no other sites for X and Y in the vector. The promoter is directed towards the Y site. The insert containing only an ORF provides 3 fragments after digestion with both enzymes X and Y. The ORF is cloned in the correct orientation in the vector using the single restriction enzyme Y. The size of the largest fragment of the recombinant plasmid expressing the ORF upon digestion with enzyme X is ........... bp. (answer in integer)
