Question

The evolution from vesicles to true cells was best facilitated by the development of (2 points) a membrane separating the cell from its environment organic molecules:______.

a. such as carbohydrates and lipids self-replicating molecules,
b. such as RNA and DNA inorganic molecules,
c. such as nitrogen and oxygen

Answer 1

self replicating molecules, such as RNA and DNA

Step-by-step explanation:

Answer 2

b. such as RNA and DNA

Step-by-step explanation:

DNA and RNA represent essential molecules present in all organisms. These nucleic acids (DNA and RNA) are composed of large chains of nucleotides that function to synthesize proteins required for cellular processes and to produce cell structures. Both RNA and DNA are highly stable biomolecules capable of storing and transmitting genetic information, which has been a requisite for the evolution of modern cells. Moreover, it is important to note that DNA is a double-stranded molecule and therefore it is more stable than single-stranded RNA.
