Creating a genetic duplicate of an organism using biotechnological methods is known as reproductive cloning.
<h3>Reproductive cloning</h3>
Cloning generally refers to the production of clones.
Clones are exact copies of an organism or something.
When it comes to living organisms, clones are both genetically and physically the same.
Thus, creating a genetic duplicate of an organism is a form of cloning known as reproductive cloning.

Answer:
A boy brought a pair home as pets.
Explanation:
As small organisms will not have any major adaptations for moving quickly or flying to whole another country, hence it is not possible for the snail to travel from Africa to Florida with small animals. Getting stuck on the airplane wing is also not correct as they would have been wiped out by the wind pressure or might have not be able to survive. Hence, the most logical explanation for the snail to get transported to Florida is by a boy who might have brought them as a pet.
Answer:
C) The amount of A is always equivalent to T, and C to G
Explanation:
Chargaff's rule was given by the Austrian chemist, Erwin Chargaff in late 1940s. It explains the composition of the four bases i.e. Adenine(A), Guanine(G), Thymine(T) and Cytosine(C) in a DNA molecule. According to it, purine and pyrimidine bases are always found in 1:1 ratio in a DNA molecule. A and G are purine and T and C are pyrimidine bases and a purine always forms a pair with pyrimidine base hence the amount of A will always be equal to T and amount of G will always be equal to C. This rule forms the basis for the Watson and Crick pairs in DNA double helix model.
A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
