RNA Flashcards
1
Q
Describe the structure of RNA
A
Consists of a ribose sugar, phosphate and nitrogen containing bases
2
Q
Where is RNA found?
A
In the cytoplasm
3
Q
What is a key role of cytoplasm?
A
Key role in proteinsynthesis
4
Q
What are the differences between DNA and RNA?
A
- DNA contains the pentose sugar deoxyribose, whilst RNA contains the pentose sugar ribose
- RNA has uracil (U) instead of thymine (T)
- polynucleotide is usually single stranded
5
Q
State the function of RNA
A
RNA is used to transfer genetic information from the DNA to the ribosomes
6

Q
What are the three different types of RNA?
A
(messenger RNA) mRNA
(Transfer RNA) tRNA
(Ribosomal RNA) rRNA
8
Q
What is the function of mRNA?
A
A copy of genetic code for one protein and takes code to the ribosome
9
Q
What is the function of tRNA?
A
Delivers amino acids to the ribosome to form a polypeptide
