Question

9- The results of this type of DNA analysis are often used to help

determine *
A) the number of DNA molecules in an organism
B) if two species are closely related
the number of mRNA molecules in DNA
OD) if two organisms contain carbohydrate molecules

Answer 1

B) if two species are closely related.

Step-by-step explanation:

DNA analysis is used to determine the relationship between two species in order to check their relations with each other because DNA molecules has all the information about the organisms. If there is more similarities between two organisms so they are more closely related to each other while on the other hand, if there is no similarities between two species so we can say that there is no relationship exists between two organisms or species. All this discussion describes the usefulness of DNA analysis.
