conserve energy.
15. which of the following statements describes the central dogma of molecular biology?

biological information in a cell passes from dna to rna to proteins.
biological information in a cell passes from rna to proteins to dna.
biological information in a cell passes from rna to dna to proteins.
biological information in a cell passes from proteins to rna to dna.

14: Operons allow prokaryotes to replicate DNA at the appropriate time.

Operons are specific regions of genes that are linked to a singular process. They ensure that the expression of these genes does not go unchecked and only occurs when necessary. Two key examples of this in humans are the lac operon and trp operon. 

15. The central dogma of molecular biology is:

DNA to RNA to Proteins

Protein Synthesis occurs in 3 steps. 

First our DNA is translated into RNA. Next the RNA is sequenced into Amino Acids by reading the corresponding 3-Base Codons. These Amino Acid sequences form various protein structures.
