DNA/RNA Identification Practice
Look at the following strands and determine if it is DNA or RNA. If the strand is
DNA, write the mRNA strand and the protein. If the strand is RNA, just make the
protein. Then use the chart to identify the trait that is expressed in the
caterpillar/butterfly if the gene is turned on.
1. What is the following strand?
AUGGGACCGAAU
mRNA:
Protein:
Trait Expressed:
2. What is the following strand?
TACAAGGTTACG
mRNA:
Protein:
Trait Expressed:
What happens if
this protein gets
denatured? Will
the trait still be
expressed?
3. What is the following strand?
AACGCGTTAGCT
mRNA:
UUGCGCAAUCGA
Protein:
Trait Expressed:
What is the following strand?
