Answer:
The correct answer would be "The sticky ends of fragmented DNA are joined with vector DNA".
Recombinant DNA or rDNA refers to the DNA that has been artificially formed by joining the fragments of DNA of two or more species.
The fragments are joined by creating the sticky ends in the DNA fragments.
These sticky ends are complementary to each other which helps the fragments to join to each other.
For example, the sticky end of a gene of interest and the sticky end of the vector DNA joined together to form a recombinant vector.
Answer:
Appendicular skeleton
Explanation:
The carpals are bones that make up part of the hand, so the Appendicular system would be an appropriate answer. The Appendicular system got its name because it is the appendages of the axial skeleton. Your hand (as well as your arms , legs, pelvic girdle, feet,etc.) is considered your appendage so it would make sense for the bones that allow your wrist to move and rotate are considered it as well.
B) The number of neutrons always equals the number of protons.
