Q

What is DNA replication

A

DNA replication is the process by which 2 identical cells of DNA are made

14
Q

What are complementary strands

A

Two strings of DNA with opposite matching base

15
Q

What is genetic code

A

The sequence of the nucleotide bases

16
Q

Explain the steps of DNA replications

A

Helixase breaks the hydrogen bond between the complementary base unzipping the DNA. Then DNA polymerase attaches new base to the old base then ligas attaches the DNA pieces together

17
Q

What is the result of the DNA replication

A

Two identical DNA molecules

18
Q

Three parts of the nucleotide

A

phosphate sugar base connect base sugar phosphate

19
Q

what did waston and crick work on

A

waston and crick work together yo gather information on DNA

20
Q

What did Franklin do

A

Found that DNA is a helix chargaff showed A-T,C-G base pairing

21
