1. 1. Lysogenic pathways are a latent period that extends through various replication cycles and these genes are integrated into the host chromosome and will stay there for a couple of divisions before being replicated. Binary fission is asexual reproduction and the body of a organism will split spontaneously. Binary fission and lysogenic reproduction is very different for the virus enters the host and stays there as they reproduce however binary fission splits spontaneously.
2. 2. Conjugation is a mode of gene transfer that is possible whe one of the cells has an F plasmid among prokaryotic species while bacteria transformations is when a DNA is changed and therefore a bacteria is able to survive antibiotics. The way they fit together is that bacterial transformations may happen through conjugation because bacteria cells swap out with DNA to prevent the bacteria’s being destroyed.
3. 3. A plasmid is a small bacterial DNA molecules that has a few genes and is replicated independently of the bacterial chromosome. A retrovirus is any of a group of viruses that contain two single-strand linear RNA molecules per virion and reverse transcriptase. The plasmid is formed many retroviruses which use enzymes to reverse transcriptase to form DNA and RNA.
4. 4. An operator is a segment of DNA in which a repressor binds. Hydrolysis is a reaction in which water reacts with a compound to produce another compound. Similar to each other, hydrolysis components attach to water molecules, the operator attaches to a protein.
5. 5. An okazaki fragment is a short fragment of DNA which is created on a lagging strand during DNA replication. A restriction enzyme is an enzyme that cuts double stranderd or single stranded DNA. Hence an okazaki fragment comes from the cut strand that is cut from the restriction enzyme.
1. Instructions for carrying out DNA molecules chromosomes lay in the hands of ribosome that are attached to membrane networks that snake their way through the cells. During protein synthesis, the amino acids are separated and bounded into new chains. Nuclosome packing is what determines if the section of DNA becomes transcribed leading to the regulation of genes that will be copied over. RNA interferences happens when RNA molecules pair themselves with themselves leading to t .
2. The promoter is a DNA sequence t at allows a gene to be transcribed and RNA polymerase initiate this transcription. The operator is a segment of DNA that that a repressor binds to and it is located between the promoter and genes of operon. Repressors bind to the operators in DNA and it bends, blocking transcription.
3. The gel electrophoresis separates the DNA fragment and in DNA fingerprinting a given sample is cut up with the restriction enzyme and run through the electrophoresis and that results in the DNA polymorphism being checked.
4. Eukaryotic cells have a nucleus and a double membrane. The prokaryote has no nucleus. In a prokaryote every organelle is attached to a membrane whereas a eukaryotic cell is composed of a cytoplasm filled with many organelles because they are more complex. DNA replication in prokaryotes happens when a bacteria chromosome connects itself to the cell plasma membrane creating DNA replication. The cell makes proteins and lipids and the membrane grows while the two DNA molecules pull apart giving each DNA one. The final step is when the membranes divide.
5. The difference between a lytic and lysogenic is that the lytic cycle is when a virus enters through the membrane to get into a cell and the lysogenic cycle is when a virus enters a cell through the host cell.
