Chapter 12 Flashcards
What molecule in the heat bacteria was responsible for the transformation?
DNA ace
One type of bacteria transforming permanently into another is called
Transformation
What did the Griffith and Avery experiments show us?
Griffith - That genetic material could be passed between bacteria and create a change
Avery - That the genetic material is DNA
Viruses that infect bacteria
Bacteriophages
- It attaches tot he surface of the bacteria and injects its genetic information into it
3 rules of DNA
- Storing information
- Copying information
- Transmitting information
DNA stands for _____
And is made up of _____ (3)
Deoxyribonucleic acid
- Nucleotides
- 5-carbon sugar
- Phosphate
What are the 4 things that we did the project thing on?
A Adenine C Cytosine
G Guanine T Thymine
Watson + Crick discovered double helix model =
T-A, A-T
G-C, C-G
Things to remember
- Base pairing
- Hydrogen Bonding
- Anti-Parallel strands
Two strands of DNA run in opposite directions
DNA replications takes place in what phase?
Interphase
Proteins with highly specific functions
Enzymes
An enzyme that joins individual nucleotides to produce a new strand of DNA
DNA Polymerase
- produces the sugar phosphate bonds that joins the nucleus together :D
Telomeres
- The tips of eukaryotic chromosomes
- assist in replication
Nucleotides are joined by Covalent bonds, which is formed between the sugar of one nucleotide and the phosphate group of the next
The sugar of one nucleotide and the phosphate group of the next
Transformation
Process in which one strain of bacteria is changed by a gene or genes from another strain of bacteria
