You can't say it developed just one branch of science.
To name a few: Genomics, Genetics, Chemistry and The science of studying DNA itself. We can't forget about the uses in technology like DNA Nanotechnology.
But technically, the main branch of science developed after the discoveries about DNA was Molecular Biology.
Answer:
Yes
Explanation:
It talks about the natural selection of small, inherited variations that increase the individuals ability to compete survive and reproduce
They're two different clotting pathways that use different factors. Though, the intrinsic and extrinsic pathways come together at factor X and eventually result in fibrinogen (factor I) being converted into a fibrin clot by prothrombin (factor II).
Extrinsic begins with factor VII and intrinsic begins with factor XII
Answer:
When directed mutagenesis which is also called reverse genetics is used, only a single mutation per genome is introduced. In contrast, the number of mutations per genome introduced by random mutagenesis is usually difficult to control. It is likely that the strain you obtained with a mutation in gene X after random mutagenesis contained an additional mutation or perhaps multiple mutations which ultimately was/were responsible for loss of virulence in your favorite pathogen.
