Concept explainers

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.

An acute leukemia patient presents with blast morphology that is of neutrophil lineage with Auer rods and pseudo−Pelger-Huët nuclei, myeloperoxidase, and Sudan Black B. Cytogenetic analysis reveals a t(8;21)(q22;q22) translocation in the majority of the blasts. Which classification of AML best fits this morphology, immunophenotyping, and cytochemistry? Select one: a.AML with recurrent genetic abnormalities b.AML with multilineage dysplasia c.AML, therapy-related d.AML not otherwise categorized

Sickle cell anemia is a favorable mutation. There is only one amino acid dillerent in Sickle hemoglobin (S) as compared with normal adult hemoglobin (A). Persons with sickle cell trait (AS) are able to survive in malarious areas. i) A couple each having sickle cell trait have five children. What is the probability thas they will have a child with sickle cell disease?
You have the following reagents available Rat anti-Keratin 8 antibody specific for mouse Keratin 8, Rabbit polyclonal antibody against mouse keratin 5 and antifade reagent with DAPI to stain DNA. Both primary antibodies work best at 1:500 dilution. A) What additional reagents would you need to perform immunostaining of frozen sections of mouse thymus tissue for Keratin 8 that is expressed in cortical thymic epithelial cells and Keratin 5 that is expressed in mouse medullary thymic epithelial cells? B) Create a staining protocol including all tubes and appropriate controls to stain 4 slides with frozen thymic sections. You will need 200ul of antibody staining solution for each slide.
An example of dosage as it applies to blood group antigens is: Question 2 options: Every antibody specificity will react with cells with a homozygous expression Some antibody specificities may only react with an antigen with homozygous expression Some antibody specificities may only react with an antigen with homozygous expression Every antibody specificity will react with cells with a heterozygous expression
Please ASAP. Thank you. The following diagram represents the results of hemoglobin samples of 5 patients (1-5) that were run on an electrophoresis gel at pH 9.2. The first 3 lanes show the control samples, for comparison. Consider Patient 4 and Patient 5. If patient 4 is female and patient 5 is a male, and they conceive a child together, is there a good chance that the child will have sickle cell anemia (the disease)? Answer Yes or No

Question 4 Listen A gene known as H is epistatic to the ABO blood type genes. Based solely on this statement which of the following is possible? A) An individual with type A blood could be phenotypically hh even if they are genotypically Hh B) An individual who is genotypically IAA could be phenotypically type O if they are also hh C) An individual who is hh is more likely to be phenotypically type A than type B D) None of the above could ever be possible.

The immunoglobulin molecules of a particular mammalian species have kappa and lambda light chains and heavy chains. The kappa gene consists of 250 V and 8 J segments. The lambda gene contains 200 V and 4 J segments. The gene for the heavy chain consists of 300 V, 8 J, and 4 D segments. If just somatic recombination and random combinations of light and heavy chains are taken into consideration, how many different types of antibodies can be produced by this species?
Regarding the production of recombinant monoclonal antibodies, it is CORRECT to state that: * (JUST ONE STATEMENT IS CORRECT) (A) Chimeric and humanized antibodies differ in relation to the percentage of sequence of the constant chain of molecules from the human genome (B) Chimeric antibodies are industrially produced by joining purified protein fragments of the Fab fraction of murine antibodies and the constant portion of human antibodies. (C) When using cells dependent on the DHF amplification system, we must use a vector containing the coding information of the light and heavy chains and another vector that contains the coding sequence of the enzyme dihydrofolate reductase (D)The industrial purification of monoclonal antibodies should preferably use an initial step based on the use of affinity columns, which will bind the antibodies by the Fc fraction (E) The use of amplification systems such as GS and DHFR has as main objective to make the production of monoclonal antibodies…
