Examination of chromosomes in karyotypes is performed on chromosomes in what stage of mitosis?

What is a heteroduplex?

A medical laboratory scientist performs fluorescence in situ hybridization (FISH) on interphase chromosomes using a probe to chromosome 21. In all cells examined, two signals were seen. These results are interpreted as:

A melt curve analysis was performed to genotype hepatitis C virus (HCV), which has been identified in a patient. When the derivative of fluorescence was plotted versus the temperature for the patient’s isolate as well as for a known genotype of HCV, the two sequences had identical peaks and thus the same Tm. Which of the following is the correct interpretation of these results?

During interphase FISH analysis of a normal specimen for the t(9;22) translocation, one nucleus was observed with two normal signals (one red for chromosome 22 and one green for chromosome 9) and one composite red/green signal. Five hundred other nuclei were normal. What is one explanation for this observation?

Which is a frameshift mutation?

A reference segment of DNA has the following sequence: GCTCACCATGG. Insertion of AG occurs between positions 7 and 8 in a particular genetic disease. How is this mutation denoted by accepted nomenclature?
