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:
2 : 1
Explanation:
- The surface area of the cube;
Area of one (1) side * 6 sides = 3 *3 * 6 = 54 cm²
Length * Width * Height = 3 * 3 * 3 = 27 cm³
- Surface area – to – volume ratio;
54 : 27 = 2 : 1
