Answer:
the transfer of genetic material from one population to another
Explanation:
Arthritis is a joint disorder involving joint inflammation.Pain is often localized to only the affected joint. Osteoarthritis is a wear and tear type of arthritis often affects aging population affecting joints in hands,knees and lower back. Heberden's node is an example and develops around middle age thus Wendell might have this.
Answer:
Transgenic organism:
Transgenic organism may be defined as the organisms whose genetic makeup has been modified by the molecular techniques. These transgenic organism are mainly produced in the laboratory for research work. The genes of one species can be modified or some other gene has been inserted in the organism.
Advantage of transgenic crop.
The transgenic crop has been produced by the genetic alteration of the crop. The main advantage of the transgenic crop is to develop the enhanced quality and quantity of crop. Vitamin rich golden rice has been produced by the transgenic crop.
Answer:
b. Restriction enzymes cutting DNA
Explanation:
Restriction enzymes are the enzymes that cut the DNA molecules. Their specific feature is that they digest the specific DNA sequences only. These specific DNA sequences are called restriction sites. When some restriction enzymes digest the DNA, DNA fragments with single-stranded ends are produced. These single-stranded overhangs are called sticky ends. They are called so since the DNA fragments produced by digesting DNA with one restriction enzyme have complementary overhangs that spontaneously base pair.
