Multiple Choice

How is the information encoded in DNA actually used by organisms?

Proteins are built directly from the information in the DNA.

DNA is translated into protein and then transcribed to RNA.

DNA migrates throughout the cell and interacts directly with other molecules in the cytoplasm.

The information in DNA is transcribed to RNA and then usually translated into protein.

Verified step by step guidance

Understand that DNA contains the genetic instructions for the development and functioning of living organisms.

Recognize that the process begins with transcription, where a specific segment of DNA is copied into RNA (specifically mRNA) by the enzyme RNA polymerase.

Note that the mRNA, which carries the genetic information, then exits the nucleus and enters the cytoplasm of the cell.

Learn that in the cytoplasm, the mRNA is translated into a protein by ribosomes, which read the sequence of mRNA nucleotides in sets of three, called codons.

Realize that each codon specifies a particular amino acid, and the sequence of codons determines the sequence of amino acids in the protein, thus translating the genetic code into a functional protein.
