LESSON 3 - PRELIM Flashcards
1
Q
2 steps in gene expression:
A
- DNA to mRNA (Transcription)
- mRNA to proteins (Translation)
2
Q
Some genes are transcribed in large quantities because
we need large amount of this protein
Some genes are transcribed in small quantities because
we need only a small amount of this protein.
