UM Intro Bio

@UMBiology #helicase splits the DNA strands then #primase provides 3'OH group. Polymerase attaches bases then DNA ligase completes strands.

@kacavitt Excellent specificity on #primase!

@dance_freak15 ????

@marypayne_ Are these all of the enzymes?

@maryscottpolk Are you "making" energy?

@michael_z64 Is the carbon already oxidized when you have NAD+

NAD+ is a coenzyme that picks up a hydrogen atom and two electrons from the glucose molecule to form NADH @UMBiology #NADH #redox

@emilyludwigsen @cshackelford98 Woman.

@UMBiology #phospholipid the hydrophobic tails are attracted to form a bilayer are attracted to avoid water

@UMBiology hydrophobic tails interact with others in interior of bilayer & the hydrophilic heads interact w/ H2O on exterior #phospholipid

@kbgraant Yeets?

@UMBiology hydrophilic heads interact with water while the hydrophobic tails interact with each other #phospholipid

Hydrophobic tails are repelled by water and interact with each other while hydrophilic heads interact with water #phospholipid @UMBiology

@UMBiology hydrophobic tails interact w/each other in interior of bilayer & the hydrophilic heads interact w/H2O on exterior #phospholipid

#helicase separates helix,#primase makes primer,DNA polymerase matches bases&builds phosphodiester bonds,ligase links fragments @UMBiology

#helicase unzips the DNA allowing #primase to lay down a primer jumpstarting polymerase laying down RNA then ligase closing gaps @UMBiology

@kristen_olson13 but why?
