- Phosphate group (circle)
- Pentose sugar (pentagon)
- Nitrogenous base (square)
2
Q

3
Q
What is nucleic acid?
A
A chain of nucleotides bonded together.
4
Q
How does RNA differ from DNA?

Ribose sugar
Single stranded
Uracil instead of thymine
5
Q
What is mRNA?
A
A copy of one gene
6
Q
What is tRNA?
A
Two binding sites: one for amino acids, and oneness or mRNA.
Works by bringing in the correct amino acids to the ribosome in the correct sequence.
