Allele specific oligonucleotides (ASO) can be used to determine the different alleles present in a DNA sample. Single sperm, whi

ch have completed meiosis, can be used for a polymerase chain reaction (PCR). The amplified DNA is then spotted to filters and hybridized with probes that recognize single nucleotide differences. A sperm sample was collected from a single individual and DNA was extracted from individual sperm. For each DNA sample, four different regions of the genome were amplified using PCR (called A, B, D, and E). For each DNA sample, ASO probes were used to determine the allele present (Either allele 1 or 2) for each region of the genome amplified. X indicates the allele is present and - indicates the allele is not present.

(Notice that there are only six classes of genotypes among the products of meiosis. For three segregating genes, you would expect to see eight different genotypic combinations. The missing genotypes are the DCO combinations and thus you should figure out what combinations are missing and assign them a value of zero)
What is an estimate of the map distance for each pair of genes?
(for unlinked gene pairs enter 50 and round off your answer to one significant digit to the right of the decimal point, i.e. 12.8 mu. If can't determine linkage, enter "-1")
A-D distance?
D-E distance?

Explain what is meant by the term transverse section
KatRina [158]

Answer:

A transverse section is a cross-sectional part that is achieved by cutting the body or any part of the body structure in real or with help of imaging techniques in a horizontal plane. That plane crisscrosses the longitudinal axis at a 90-degree angle.

Explanation:

A cross section obtained by slicing, actually or through imaging techniques, the body or any part of the body structure, in a horizontal plane, i.e., a plane that intersects the longitudinal axis at a right angle. Because actual sectioning in the transverse plane results in inferior and superior portions, an anatomic transverse section may be a two-dimensional view of the cut surface on the inferior aspect of the superior portion, or of the superior aspect of the inferior portion. By convention, in medical imaging transverse sections usually demonstrate the form

Diagnostic coding is the conversion of written accounts of sicknesses, diseases and wounds into codes from a precise grouping. In medical classification, diagnosis codes are used as a share of the clinical coding process together with intervention codes. So for the problem, the answer is P90. It is a billable ICD code used to stipulate an analysis of convulsions of newborn.
