Step by step
Solved in 3 steps
- identify the following genetic terms in order from smallest to largest.Gene - Nucleotide - Base-pair - Genome. First is the smallest in size:a. You have a test tube containing 5 ml of a solution of bacteriophages, and you would like to estimate the number of bacteriophages in the tube. Assuming the tube actually contains a total of 15 billion bacteriophages, design a serial dilution experiment that would allow you to estimate this number. Ideally, the final plaque-containing plates you count should contain more than 10 and fewer than 1000 plaques.Briefly describe the structure of bacteriophage.
- Describe the structure of a bacterial genome, and explain how it differs from a eukaryotic genome. Explain what a plasmid is, and describe the role of plasmids in the spread of antibiotic resistance genes. Explain how bidirectional semiconservative DNA replication copies the circular chromosome of a bacterium during cell division. Explain the steps of replication by DNA polymerase, including initiation, elongation, and termination. Explain the different kinds of mutations and how they occur.The genome of bacteria cells, eukaryotic cells, and viruses are all about the same size. True or FalseDescribe the process using the terms provided. DNA replication: 3' end, 5' end, DNA polymerase 1, DNA polymerase 3, helicase, lagging strand, leading strand, ligase, primase, single-stranded binding proteins, topoisomerase
- List and describe the sequential steps of DNA replication in prokaryotic (bacterial) cells. Be sure to include the key enzymes involved in this process.Fill in the blank spaces below with the most appropriate terms. The word bank is not provided. DNA replication in bacterium Escherichia coli begins at a site in the DNA called At the replication fork, the strand is synthesized continuously while the strand is synthesized discontinuously (in fragments). The new DNA strand, which is synthesized discontinuously, initially consists of short DNA pieces that are called A short RNA primer at the beginning of each of the DNA fragments is synthesized by an enzyme called and this RNA primer is later removed by the enzyme called using its activity. Single-strand breaks (nicks) that are left behind in this process are sealed by the enzyme called A Moving to another question w!l save this resporse Quebon 4 InThe holoenzyme consists of 2 DNA polymerase core enzymes single sliding clamp-loader complex two sliding clamp
