DNA as the Genetic Material
Multiple Choice
In the context of DNA as the genetic material, what does DNA provide the code for?
A
The amino acid sequence of proteins (and thus functional RNAs via transcription and translation pathways)
B
The chemical composition of the cell membrane phospholipid bilayer
C
The assembly of ribosomes from pre-existing ribosomal proteins without involving RNA
D
The exact three-dimensional folding pattern of every protein independent of its amino acid sequence
Verified step by step guidance1
Understand that DNA contains the genetic instructions used in the development and functioning of all living organisms.
Recognize that DNA sequences are transcribed into messenger RNA (mRNA), which then serves as a template for protein synthesis during translation.
Recall that proteins are made up of amino acids arranged in a specific sequence dictated by the nucleotide sequence in DNA.
Note that the amino acid sequence of a protein determines its structure and function, making DNA the code for the amino acid sequence of proteins.
Eliminate other options by understanding that DNA does not directly code for membrane lipids, ribosome assembly without RNA, or protein folding independent of amino acid sequence.
