Question

Katherine asked her lab partner to explain how the structure of DNA affected the structure of a protein. Her partner gave her this information.

Select TWO pieces of information that are NOT accurate.

Responses
A All of an organism's genetic information is carried in their DNA.All of an organism's genetic information is carried in their DNA.
B The sequence of sugar and phospates in DNA and RNA code for amino acids.The sequence of sugar and phospates in DNA and RNA code for amino acids.
C A gene is a small segment of DNA that codes for the production of one protein.A gene is a small segment of DNA that codes for the production of one protein.
D A codon is a group of three bases in mRNA that code for an amino acid.A codon is a group of three bases in mRNA that code for an amino acid.
E DNA can be broken into genes that are then taken to the ribosome to make a protein.DNA can be broken into genes that are then taken to the ribosome to make a protein.

Answer 1

B and E

- B is incorrect because amino-acid coding information comes from the sequence of nitrogenous bases (A, T/U, C, G), not the sugar–phosphate backbone.
- E is incorrect because DNA is not physically broken off and carried to ribosomes; genes are transcribed into mRNA, and the mRNA is what is transported to and read by ribosomes.
