The start codon is the first codon which is AUG this codon codes for Methionine amino acid. There are 3 stop codons which are UAA, UAG, UGA

Virus mediated gene transfer is the technology in which virus is used as a vector. We use in transferring our desired gene or targeted gene of interest to host cell by viral vector, such as bacteriophage. It attacks the bacterial cell and by degrading bacterial genome it release the desired gene of interest in bacterial cell and by using bacterial replisome it replicates in more number. By this process it also uses some sequence of bacterial genome too and create a recombinant genome and multiplies in a large number inside the host. This special phase of gene transfer or lysogenic gene transfer. After the process viral cell get degraded and comes out of the host cell.

A restriction enzyme cuts a precise DNA sequence and creates mainly two types of ends: blunt end and flush or cohesive end. Blunt end occurs when cuts are straight, there will be no overhanging base pair between two ends. Whereas flush end or cohesive end forms by staggered cutting of the sequences. There will be overhanging base pair in both the ends of DNA sequence.

The reproductive problem is, disease and dysfunction play a central role in women's health. Men's case is different from this. The main burden of the disease in females is related to their reproductive system and reproductive function. On the other hand, men die due to their "vices", women suffer due to the tasks related to it and the nature-assigned physiological duty for the survival of the species.

It is a chain reaction to synthesize DNA polymer using a template DNA. It involves cycles of denaturation, annealing and amplification. Enzyme used is Taq polymerase, from Thermus aquaticus.

Microinjection is a technique of delivering DNA directly into the nucleus of the cell.

Many branches are there which includes, Molecular biology, Genetic Engg, Plant bt, animal bt, Biochemistry, Bio process engg. Etc

Lipids are chemicals involving ester bond formation between long chain of fatty acids having carboxyl group at end and alcohols giving phosphate group at another end. They form the cell membrane.
