Question 7(Multiple Choice Worth 4 points)
Maurinko [17]

Answer: The correct option is B (self-replicating molecules, such as RNA and DNA)

Explanation:

The current theory of the process of evolution makes use of present day knowledge of genes and chromosomes to explain the source of genetic variation upon which natural selection works. These genes are discrete units of inheritance which determine hereditary characteristics. All the information for the inheritable characteristics of an individual are contained in these genes.

When a cell divides, the genes duplicate themselves so that each daughter cell has an identical set of genes as the original parent cell. These genes are passed from parents to offspring in the gametes of the parents.

Gene are found in the DNA( Deoxyribonucleic acid) molecules or RNA (Ribonucleic acid) molecules. These molecules are capable of self replication due to a process called mutation. Mutations are random changes in DNA that alter genetic information and sin introduce new characteristics. They may occur

--> in body cells or

--> during gamete formation.

Thus, evolution from vesicles to true cells is through self replicating molecules through the process of mutation which is the raw material for evolution
