help. 1. To produce a specialized-transducing mycobacteriophage construct, a cosmid bearing the allelic exchange substrate is electroporated in Mycobacterium smegmatis, followed by an incubation at 30°C. True/ False 2. A recombineering system involves the over-expression of recombinase proteins, which allows the use of a short DNA fragment as allelic exchange substrate, but can also be combined with the use of a mycobacteriophage construct. True/ False
Give only typing answer with explanation and conclusion Your analysis has identified that this new organism has same chromosomal structure as that of eukaryotes on earth. However, the average length of linker DNA of the new organism is 100 bp. If the haploid genome of the new organism has a size 6 billion bp, how many nucleosomes will be in this new organism?
Please help with all of these! thank you so much! Neutral regions of a species’ genome that are distant from any selected sites have apairwise diversity (?) of 0.01. Other regions of the genome have reduced genetic variation,and selective sweeps could be responsible for the reduction. Assume that selective sweepshappen at a rate of 10^-10 per bp, and they take 500 generations to reach fixation. Therecombination rate in regions where selective sweeps might occur is 10^-8 per bp. Theeffective population size of the species is 10^5. A. Find the expected genetic diversity (? per bp) in regions where selective sweepsmight be occurring.B. Find the deleterious mutation rate (per bp) that would be required to produce anequivalent reduction in genetic diversity as a result of background selection (BGS)?Assume the same recombination rate as above.
The human genome contains approximately 106 copies of an Alusequence, one of the best-studied classes of short interspersed elements(SINEs), per haploid genome. Individual Alu units share a282-nucleotide consensus sequence followed by a 3@adenine@richtail region [Schmid (1998)]. Given that there are approximately3 * 10^9 base pairs per human haploid genome, about how manybase pairs are spaced between each Alu sequence?
Question:- The success of renal transplantation depends on three human histocompatibility genes, HLA-A, HLA-B and HLA-C, which must match between the donor and the receiver. A single mismatch may cause the kidney rejection. Each gene has multiple co-dominant alleles. These three genes are located very close to each other on chromosome 6, so that the recombination rate is very low (below 1%). The father has the following genotype: A1, A2, B24, B10, Cw4 and Cw7 and the mother is A1, A1, B11, B7, Cw5 and Cw8. Their first boy is A1, A1, B24, B11, Cw7 and Cw8. What is the probability that the second child is compatible with his/her brother?
Discuss Concepts The genome of the yeast Saccharomyces cerevisiae is only about 0.4% the size of the human genome, yet itcontains about 30% as many genes as are in the human genome. Given that, which of the features of the human genome would you expect to find many fewer of in the yeast genome?
Part1: Using the DNA nucleotide sequences for the wild-type and mutant genes in the following tables, determine the complementary mRNA sequence for the five portions of the Mc1r gene provided. (Note: You are only transcribing short portions of the DNA sequence for this protein. The actual gene contains 954 base pairs.) Part2: Using completed the mRNA sequence, determine the resulting amino acid sequence of the MC1R protein. (Note: You are translating only a portion of protein. The full protein is 317 amino acids long. The numbers above the columns in the tables indicate amino acid positions in the protein sequence.) You may use the genetic code chart provided
52. Papaya plants are very susceptible to the papaya ringspot virus (PRSV), which stunts the growth of the fruit and negatively impacts the taste. By 1995, PRSV wiped out the Hawaiian papaya crop completely and made it impossible to produce papaya commercially. In 1998, Cornell University developed a genetically modified papaya called Rainbow that was resistant to PRSV and introduced it to Hawaii. Currently, 80% of the papaya cultivated in Hawaii is genetically modified to be resistant to PRSV.Which of the following rows identifies the effect of PRSV on the original papaya population and the reason why the population recovered? Select one: a. Effect on the Original Population Reason for Recovery Population bottleneck Some papaya had the PRSV-resistance gene. b. Effect on the Original Population Reason for Recovery Increased gene flow The PRSV-resistance gene had to be artificially introduced to the papaya genome c. Effect on the Original Population Reason…

C5. A human gene called the β-globin gene encodes a polypeptide that functions as a subunit of the protein known as hemoglobin. Hemoglobin is found within red blood cells; it carries oxygen. In human populations, the β-globin gene can be found as the common allele called the HbA allele, and it can also be found as the HbS allele. Individuals who have two copies of the HbS allele have the disease called sickle cell disease. Are the following descriptions examples of genetics at the molecular, cellular, organism, or population level? A. The HbS allele encodes a polypeptide that functions slightly differently from the polypeptide encoded by the HbA allele. B. If an individual has two copies of the HbS allele, that person’s red blood cells take on a sickle cell shape. C. Individuals who have two copies of the HbA allele do not have sickle cell disease, but they are not resistant to malaria. People who have one HbA allele and one HbS allele do not have sickle…
Ch. 15-1 In 1918, an influenza pandemic that originated with avian flu killed 50 million people. Researchers isolated samples of that virus from bodies of infected people preserved in Alaskan permafrost since 1918. From the samples, they sequenced the viral genome, then reconstructed the virus. The reconstructed virus is 39,000 times more infectious than modern influenza strains, and 100 percent lethal in mice. Understanding how this virus works can help us defend ourselves against other strains that may arise. For example, discovering what makes it so infectious and deadly would help us design more effective vaccines. Critics of the research are concerned: If the virus escapes the containment facilities (even though it has not done so yet), it might cause another pandemic. Worse, the published DNA sequence and methods to make the virus could be used for criminal purposes. Do you think this research makes us more or less safe?
