4162408172transformationprocess where 1 strain of bacteria is changed by genes from another strain of bacteria0
4162408173Bacteriophagevirus that infects bacteria1
4162408174bacteriophage attaches to the surface of the bacterial cell and injects its genetic information into it. The phage DNA is incorporated into the bacterial DNA and the phage uses the bacterial cell to produce new bacteriophages.how bacteriophages work2
4162408175to store, copy, and transmit genetic information in a cellDNA's roles (3)3
4162408176storing informationforemost job: contain all instructions for determining what and organism will be and the process of developing from a single cell to an adult.4
4162408177copying informationbefore a cell divides it must make complete copy of every gene for the new cell.5
4162408178transmitting informationgenes must be transmitted from one generation to the next.6
4162408179deoxyribonucleic acidDNA stands for ___7
4162408180nucleotides joined into long strands/chains by covalent bonds.DNA is made of ___8
4162408181nucleotidesNucleic acids are made of ___9
41624081825 carbon sugar phosphate group nitrogenous base3 basic components of nucleotides10
4162408183nitrogenous baseterm for a base that contains nitrogen11
4162408184adenine thymine cytosine guanineDNA's 4 nitrogenous bases12
4162408185the sugar group of one nucleotide and the phosphate group of the next nucleotide.In DNA, covalent bonds form between ___13
4162408186[A]=[T] and [C]=[G]; in DNA, the amount of adenine and thymine found are equal and the amount of cytosine and guanine are equal.Chargaff's rule14
4162408187double helixthe shape of DNA; 2 DNA molecules twist around each other like a ladder.15
4162408188double helix explains1.)Chargaff's rule of base pairing, 2.)how two strands are held together, and 3.)how DNA can function as a genetic carrier16
4162408189anti-parallel strands2 strands of DNA run in opposite directions17
4162408190holds 2 strands of the double helix together; hydrogen bonds form only between certain nitrogenous bases. These weak bonds allow the structure to separate.Why is hydrogen bonding in DNA important?18
4162408191base pairingWhat do we call the following: adenine pairs with thymine cytosine pairs with guanine19
4162408192Each base on one strand pairs with only one base on the opposite strand; each strand has information necessary to reconstruct the other half (strands are complementary)how does base pairing in double helix explain how DNA can be copied?20
4162408193replicationa copying process which duplicates the DNA21
4162408194unzippinga process (mediated by enzymes) which separates the two strands of DNA, allowing 2 replication forks to form.22
4162408195unzipping the dna breaking the hydrogen bonds unwinding 2 strandsrole of DNA Helicase enzymes in replication23
4162408196DNA polymeraseenzyme that joins individual nucleotides to produce and proofread a new DNA strand.24
4162408197telomeresdna at tips of chromosomes which is difficult to replicate25
4162408198telomerasean enzyme which helps replicate the telomere region by adding short repeated DNA sequences to telomeres; helps prevent genes from being damaged or lost26
4162408199nucleosomesbeadlike structures of DNA and histones27
4162408200in the S phaseDNA replication occurs when?28
4162408201prokaryotic DNA replicationstarts in a single spot and goes around in 2 directions until the entire chromosome is copied29
4162408202eukaryotic DNA replicationbegins at many different spots on the DNA molecule and proceeds in 2 directions until the entire chromosome is copied30
4162458810Single - stranded binding proteinproteins that bind to the freshly split DNA molecule to keep the two strands apart.31
4162461195Leading StrandStrand of freshly copied DNA which is continuously made32
4162461196Lagging strandStrand of freshly copied DNA which is discontinuously made - resulting in fragments of DNA which will need to be strung together later.33
4162461197Okazaki fragmentsDisjointed pieces of DNA which are created on the lagging strand.34
4162468733Alfred Hershey and Marsha ChaseUsed radioactive materials on bacteriophages to see which material got passed on to bacteria cells, DNA or proteins. Found that DNA was the molecule responsible.35
4162468734Oswald AveryScientist who, with his team, found the molecule which results in transformation by meticulously destroying one molecule at a time.36
4162469645Frederick GriffithScientist who studied the r-strain and s-strain of bacteria and how it influenced mice.37
4162485413BacteriophageWhat is the image an example of?38
4162489588GCATWhat would the complementary DNA strand be if the original strand's sequence is CGTA?39
4162492817Rosalind FranklinScientist who conducted x-ray diffraction on DNA to discover it was a double helix shape40
4162494941Watson and CrickScientists who first build a proper model of the DNA molecule41
4162503720Erwin ChargaffScientist who discovered the amount of adenine and thymine are always equal, as well as the amounts of guanine and cytosine.42
4162511307CircularThe shape of a bacteria cell's DNA43
4162512163In the cytoplasmWhere a bacteria cell's DNA can be found44
4162513624in the nucleusWhere a eukaryotic cell's DNA can be found.45
4162589512Adenine and GuanineThe bases known as the purines.46
