Answer:
Restriction enzyme cuts out gene of interest, Gene is inserted into plasmid (circular) DNA of bacteria using same restriction enzymes, DNA ligase seals DNA together, Plasmid is inserted into bacteria (transformation)
The goal for both is to Change the DNA of the person with the genetic disease

hope this helped
stay safe
brainliest is appreciated only 1 more to level up please help :)))
Answer:
Pinocytosis is the mechanism by which living cells consume liquid droplets. Endocytosis is the general mechanism by which cells ingest foreign substances and collect them in special membrane-bound vesicles within the cell. Pinocytosis is one form of endocytosis.
Answer:
As a result of the Hershey and Chase experiments, scientists believe
that the “transforming principle” is DNA.
Explanation:
Hershey and Chase determined that DNA, not protein, was the inherent material. They resolute that a defensive protein coat was molded everywhere the bacteriophage, but that the interior DNA is what discussed its capability to produce offspring inside a bacterium. Transformation occurs when one bacterium picks up free-floating DNA and incorporates it into its own genome. When scientists first observed this behavior, it seemed that genes were transforming one type of bacteria into another, so they concluded there must be a 'transforming principle' at work.
Answer:
(A): DNA and protein
(B): The case for proteins appeared stronger until the 1940s, especially since biochemists had identified them as a class of macromolecules with great heterogeneity and function specificity, essential requirements for the hereditary material. Moreover, little was known about nucleic acids, the physical and chemical properties of which seemed far too uniform to account for the multitude of specific hereditary traits of each organism
(C): Virulent strains are pathogenic (causing disease), whereas non-virulent strains are non-pathogenic (harmless) strains.
