Section 3 - RNA and protein synthesis Flashcards
1
Q
Where does protein synthesis happen?
A
In the cytoplasm at organelles called ribosomes
2
Q
What is mRNA?
A
A smaller, copied version of a gene
3
Q
Describe how the DNA in the gene acts as a template during protein synthesis
A
The bases on RNA nucleotides line up next to their complementary bases on the DNA template. Once the bases on the RNA nucleotides have paired up with the bases on the DNA strand, the RNA nucleotides join together to make an mRNA molecule. Eventually, a whole copy of the gene is made and the sequence of bases in the mRNA copy is complementary to the sequence of bases in the DNA template.

Q
In RNA, what base is missing?
A
Thymine
5
Q
In RNA, what base is used instead of Thymine?
A
Uracil
