Genetics and DNA technology

What you'll learn

1. 1

   Think of DNA as the instruction manual for building a living thing. It's a long, twisted ladder 🧬.

2. 2

   Build a short DNA sequence by pairing the letters correctly. A always pairs with T, and C always pairs with G.

3. 3

   Let's read a DNA code to make a protein. The code is read in groups of three letters called 'codons'.

4. 4

   Now transcribe this DNA strand into mRNA: TAC CGA TTT. Type the mRNA sequence (using A, U, C, G).

5. 5

   What does the DNA letter A pair with in DNA?

6. 6

   DNA technology lets us cut and copy genes. A special enzyme called a restriction enzyme cuts DNA at specific spots, like scissors ✂️.

7. 7

   Which enzyme cuts DNA at specific sequences?
