Slide1
Unit 5 – DNA and DNA Replication
Directions: Front of card write term. On back write definition and draw picture
Slide2Chromosomes
Thread-like structure made of coiled DNA
Slide3Gene
Segment of DNA that codes for a specific trait
Slide4Nucleotide
Building block of DNA. Composed of a sugar, phosphate and nitrogen base
Slide5Double Helix
Twisted, double-stranded structure of DNA molecule. Sugar and phosphate make up the backbone
Slide6Hydrogen bond
Weak bond that holds the nitrogen bases together. Combines the nucleotides together to complete the double stranded DNA molecule
Slide7DNA
Structure that codes for all genetic information of an organism. Has the instructions for making proteins and can replicate itself. Made up of nucleotides.
Slide8Covalent bond
Strong bond that holds the sugar –phosphate backbone of DNA together
Covalent bond
Slide9Nitrogen Bases
Make up the “rungs” or “steps” the of the DNA ladder. Adenine, Cytosine, Guanine, thymine and uracil (RNA).
Slide10DNA replication
The process by which DNA makes a copy of itself before cell division
Slide11Semi-conservative
During replication, the two copies created contain one of the original strands (old) and one new strand
Slide12Helicase
Slide13DNA polymerase
Enzyme that builds nucleotides to the split DNA strands in replication. Adds the “new” strands to complete 2 new daughter DNA strands. Also, checks the replication process for errors.
