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.

1. In terms of Spo11, what does it mean if twice as many genetic sequence reads map to one location than another? Explain. 2. What does it mean if genetic reads map in different locations in difgerent strains? Explain in terms of recombination hotspots.
8. You infect E. coli cells with two strains of T4 virus. One strain is minute (m), rapid lysis (r) and turbid (t); the other is wild-type for all three markers. The lytic products of this dual infection are plated on a lawn of E. coli and the morphology of the plaques are classified. The resulting 10, 342 plaques were distributed among eight phenotypes, as follows: mrt 3467 +++ 3729 mr+ 853 m+t 162 m++ 520 +rt 474 +r+ 172 ++t 965 You decide to repeat the exact same experiment as outlined above and this time you count and classify 25, 000 plaques? How many plaques would you expect to be wild-type for all three markers? (Hint: You will need to calculate the expected DCO class for the cross above and apply that to your answer.)
Below is a diagram of the general structure of the bacteriophagel chromosome. Speculate on the mechanism by which it forms aclosed ring upon infection of the host cell. 5'GGGCGGCGACCT:double@stranded region-3' 3'- double@stranded region:CCCGCCGCTGGA5'
E. coli cells are simultaneously infected with two strains of phage λ. One strain has a mutant host range, is temperature sensitive, and produces clear plaques (genotype h st c); another strain carries the wildtype alleles (genotype h+ st+ c+). Progeny phages are collected from the lysed cells and are plated on bacteria. The following numbers of different progeny phages are obtained: Progeny phage genotype Number of plaques h+ c+ st+ 321 h c st 338 h+ c st 26 h c+ st+ 30 h+ c st+ 106 h c+ st 110 h+ c+ st 5 h c st+ 6 a. Determine the order of the three genes on the phage chromosome. b. Determine the map distances between the genes. c. Determine the coefficient of coincidence and the interference
Describe the differences between genetic complementation and recombination as they relate to the detection of wild-type lysis by a mutant bacteriophage.
34. A donor strain of bacteria with alleles a* b* c* is infected with phages to map the donor chromosome using generalized transduction. The phage lysate from the bacterial cells is collected and used to infect a second strain of bacteria that are a b c. Bacteria with the a* allele are selected, and the percentage of cells with cotransduced b* and c* alleles are recorded. Donor Recipient Selected Cells with allele cotransduced allele (%) a* b* a bc a* 25 b* a' 3c Is gene b or gene c closer to gene a? Explain your reasoning.
What is the result of conjugation between F and F cells?
when various strains of lambda phage are seeded on a lawn of e.coli, they can form clear or turbid plaques. Explain the difference between the two types of plaques. can all bacteriophage form clear and turbid plaques?
In what major way does transcription of phage DNA differ inphages T4 and T7?
During the analysis of seven rII mutations in phage T4, mutants1, 2, and 6 were in cistron A, while mutants 3, 4, and 5 were incistron B. Of these, mutant 4 was a deletion overlapping mutant5. The remainder were point mutations. Nothing was knownabout mutant 7. Predict the results of complementation (+ or -)between 1 and 2; 1 and 3; 2 and 4; and 4 and 5.
As described in Figure, host DNA is hydrolyzed into smallpieces, which are occasionally assembled with phage proteins, creatinga phage with bacterial chromosomal DNA. If the breakage ofthe chromosomal DNA is not random (i.e., it is more likely tobreak at certain spots as opposed to other spots), how might nonrandombreakage affect cotransduction frequency?
Describe the reason behind the occurrence of phage growth and release by the mating with the non-lysogenic recipient, but not with the infection by a lysogenic recipient.
