Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.

- 8) Which of the following best describes why it is possible for the bacteria to read the instructions in a human gene and produce a human protein as a result? Bacterial cells and human cells are identical and contain the same organelles Bacterial cells and human cells both use DNA to store their genetic information The genetic code is universal - the same codon codes for the same amino acid in all species The bacterial cell already contains a gene that is very similar to the human growth hormone gene1. WHY DO WE NEED GENETIC ENGINEERING?1. Assuming you have determined the sequence of a certain enzyme/protein product, how will you identify its correct DNA sequence (*some codons are redundant or wobbled) using the CDNA libary?
- 6. Similar to the class notes (Intro to Genetics), a segment of DNA (shown below) contains a promoter segment (the first 9 base pairs), a ribosome binding segment (the next 6 base pairs), and a segment that codes for protein synthesis which is started by the rest of the base pairs. ACTCCATTGAACCATTTCTATGATCCGCTAACG-... TGAGGTAACTTGGTAAAGATACTAGGCGATTGC-... A. When the DNA is induced to be copied to mRNA, the top strand is coding, meaning that the mRNA makes an identical copy of the lower strand (replacing T with U) The mRNA copy starts with the ribosome binding sequence. What is the sequence of the mRNA that will go to the ribosomes? B. What are the first 6 amino acids of the protein that are coded for by the mRNA? C.

In the Hershey-Chase experiments, why was DNA labeled with radioactive P and protein with radioactive S? Why not use radioactive carbon for DNA and radioactive nitrogen for protein? Those elements are more abundant in the cells. 2. If Hershey and Chase had picked an RNA virus as their bacteriophage, would the results of their experiment changed? Why or why not?

(Question # 21; Chapter 8-Genetics: An Integrated Approach). Speculate about the kind of differences you would expect to see if you compared a broad spectrum of mRNAs from the mutant strain grown at 37°C and the same spectrum of mRNAs from the strain when grown at 40°C. Are all mRNAs affected by the rho protein mutation in the same way? Why or why not?1. Four genes (A,B,C,D) of a bacterium code for four enzymes (A,B,C,D), which act sequentially to catalyze the production of compound D, as follows. enzyme A enzyme B enzyme C enzyme D precursor -----> compound A -----> compound B -----> compound C -----> compound D A number of mutant strains of the bacterium are isolated, which grow only on supplemented media, as outlined below.
