Unit 1 Chapter 2 Flashcards
the repeating units of a Phosphate, sugar and base that make up a double stranded molecule of DNA
Nucleotides
the name given the strand formed from DNA replication that is described as discontinuous
Lagging Strand
importance of DNA replication
To ensure that an exact copy of species’ genetic information is passed on from cell to cell during growth and from generation to generation during reproduction
the type of bonds that form between bases in DNA
Weak Hydrogen Bonds
name given to the twisted coil that two strands of DNA form
Double Helix
the strand that is formed from the continuous replication of the parental DNA strand that has the 3’ end
Leading Strand
the four requirements for DNA replication to occur
DNA, Primers, supply of DNA Nucleotides, enzymes and ATP
the way that DNA must be replicated in the DNA Parental strand that has the 5’ end
Fragments
the three parts that make up a DNA nucleotide
Deoxyribose sugar, phosphate and base
the complimentary base pairing rule that applies to DNA
Adenine(A) bonds with Thymine(T) and Guanine(G) bonds with Cytosine(C)
the word used to describe the arrangement of two strands of DNA with their sugar-phosphate backbones running in opposite directions
Antiparallel
the name given to Y-shaped structure formed when two strands of DNA separate to expose their bases
Replication Fork
what is needed for DNA polymerase to be able to function and add nucleotides to the 3’ end of the parental DNA
Primer
the carbon end from which a DNA strand can grow
3’ end
the process by which DNA is able to reproduce itself exactly
DNA Replication
