RNA Flashcards
1
Q
How does RNA differ to DNA
A
-has ribose as its Pentose sugar
-base Uracil replaces thymine
-mRNA and tRNA are single stranded
2
Q
What types of RNA are there
A
- messenger RNA (mRNA)
-transfer RNA (tRNA)
-ribosomal RNA (rRNA)
-small interfering RNA (siRNA)
3
Q
What’s the structure of m(RNA)
A
Linear with codons (base triplets)
4
Q
What length is mRNA
A
Variable based on gene copied
5
Q
What’s the function of mRNA
A
role in protein synthesis in the ribosomes in the cytoplasm. After playing its role it degrades
6
Q
What shape is tRNA
A
Clover
7
Q
What’s the structure of tRNA
A
Clover leaf shape, with anticodon (3 unattached bases) and a binding site for amino acids
8
Q
Where is ribosomal RNA found
A
Forms the organelle ribosomes
9
Q
What’s the function of ribosomal RNA
A
where the mRNA code is translated into amino acid sequence
