Structure of RNA Flashcards
1
Q
What is the structure of messenger RNA? Where is it formed?
A
- Linear structure that contains codons (mRNA triplets)
- Involved in protein synthesis by being formed in the nucleus during transcription and carrying the coding sequences to the tRNA
2
Q
What is the structure of transfer RNA? How many types are there?
A
- 20 different types found in the cytoplasm
- Clover leaf shape due to hydrogen bonding between complementary base pairs
- One end has an anticodon, and the other has a binding site for a specific amino acid
3
Q
What are the differences in the structure of mRNA and tRNA?
A
- tRNA has amino acid binding sites
- tRNA has hydrogen bonds
- tRNA has anticodons
4
Q
What is the difference between codon and anticodon?
A
Codons are trinucleotide units that are in mRNA and codes for a particular amino acid in protein synthesis. Anticodons are trinucleotide units that present in tRNA. It is complementary to the codons in mRNA.

Q
What is the differences in the structure of RNA and DNA?
A
DNA has 1 strand, whereas RNA has 2
DNA is very long, RNA is short
DNA has deoxyribose, RNA has ribose
RNA replaces thymine with uracil
