Deletion

Question 16

How does base pairing work

Answer 16

Adenine (A) pairs with thyme (T) and cytosine (C) pairs with Guanine (G)

Contains instructions needed for organisms

Question 18

Anticodons

Answer 18

Their function is to base pair with the codon on a strand of mRNA during translation

History of DNA

Answer 19

Identified in the 1860s by a Swiss chemist, Johann Friedrich Miescher
