AP Bio Unit 6 Vocb quiz

Topismerase

Relives DNA by breaking, swiveling and redoing DNA strands

Helicase

Untwists the double heliex of DNA and replication forks

Primase

Starts a DNA chain and adds RNA nucleotides one at a time

SSBs

Builds and synthesizes single stranded DNA

Lagging strand

New DNA that synthesizes disconutiously

Okazaki Fragments

Synthesizes the lagging strand

Leading strand

New DNA strand is synthesized continuously

Ori

Original of replication

Primer

Initial nucleotide strand short for RNA

DNA Ligand

Joins together gaps

DNA polymerase

the elongation of new DNA at replication fork

Fredrick Griffith

Discovered the transformation of bacteria and how genetic traits could be transferred between bacteria using DNA

Oswald Avery

DNA is a grand substandard and proved DNA hold genetic information not protein

Alfred Hershey and Martha chase

Showed that DAN enter bacteria and not protein, also confirmed that DNA caries genetic information

Erwin Chargaff

A%=C% G%=T%, and showed DNA composition differs between species

James Watson and Francis Crick

Bult the double helix model of DNA and proposed the anti—parallel strands and specific base paring

Rosalind Franklin and Maurice Wilkins

His photos releases DNA is helical and double stranded also used X-Ray Crystalography to study DNA

Matthew melson and Franklin Stanl

Proved semi-conservative DNA replication, and that each new DNA molecule has one old and new strand

Jenifer Doudnd

Co-discovered CRISPER-Cas9 and enabled gene editing and highlighted ethical concern of gene editing technologyy
