New cards

read templates

3’ to 5’

3
New cards

exonuclease

breaks phosphodiester bonds, removes primer

4
New cards

polymerase

make phosphodiester bond 5’-3’. fills gaps

5
New cards

DNA helicase

enzyme that breaks hydrogen bonds

6
New cards

primer

short, complementary RNA. Made by a special RNA polymerase (primase)

7
New cards

primase

substrate: rNTP template: DNA

8
New cards

leading strand

Starts at 3’. continuous strand in direction of helicase movement

9
New cards

lagging strand

Discontinuous synthesis starting from multiple primers. synthesize in opposite direction of helicase

10
New cards

DNA polymerase

makes phosphodiester bonds. Substrate 1: dNTP’s 2: template 3: primer: short pre-existing nucleic acid
