Scientists build models based on what they know from previous research to develop testable hypotheses. Scientists Watson and Crick first constructed an incorrect triple-helix model of DNA with the bases (A, T, C, G) arranged on the outside of the molecule.
Explain why their triple-helix model was valuable even though it was not correct.

What is the role of transcription in genetic expression?
To make a DNA copy of an RNA molecule
To make an RNA copy of a gene
To repair damaged DNA
To make a protein from an RNA molecule
The diagram below represents one of a number of different types of mutations that can occur in DNA.
This mutation can best be described as the:
pairing of an adenine (A) base with thymine (T)
the insertion of an adenine (A) base into both strands of the DNA molecule
the substitution of an adenine (A) base for guanine (G)
deletion of an adenine (A) base from the DNA molecule
Which statement best explains the fact that some identical twins appear different from one another?
Their DNA is essentially the same and the environment plays little or no role in the expression of their genes.
Their DNA is very different and the environment plays a significant role in the expression of their genes.
Their DNA is very different and the environment plays little or no role in the expression of their genes.
Their DNA is essentially the same and the environment plays a significant role in the expression of their genes.
What is the purpose of translation in genetic expression?
To convert proteins into genetic information
To convert mRNA into DNA
To convert DNA into mRNA
To convert RNA into a sequence of amino acids
