Protein Synthesis Flashcards
1
Q
Summarise transcription into a single sentence.
A
Transcription is the process of copying a single gene of DNA to mRNA
2
Q
Where does transcription take place?
A
The nucleus
3
Q
Give three ways mRNA is different to DNA.
A
- Uracil (U) replaces thymine (T)
- Only one strand instead of two
- Shorter than DNA (it only copies one gene)
4
Q
Where does mRNA go once it has been transcribed?
A
The ribosomes
5
Q
Summarise translation in a single sentence.
A
Translation is the process by which a ribosome combines amino acids together to form a protein, using the ‘instructions’ and codes in mRNA.
6
Q
What is the role of a ribosome?
A
To carry out protein synthesis (assemble amino acids to form a protein)
7
Q
What is a polypeptide?
A
A polypeptide is a chain of amino acids.
