31. Virtual karyotyping can be performed on fresh or paraffin-embedded tumors to assess copy number at these loci. 32. It is one among the three negative regulatory elements found in plasmids which control its copy number . 33. Then they compared the starch consumption of different populations to their copy number of the amylase gene. 34. "Digital karyotyping " is a technique used to quantify the DNA copy number on a genomic scale. 35. In 2015, Ringo Starr's personal copy number 0000001 sold for world record $ 790, 000 on auction. 36. The other class of possible mechanisms that are hypothesized to lead to copy number variations is non-homologous based. 37. The focus of the research was copy number variations ( CNVs ), extra or missing parts of genes. 38. Additionally, single chromosome sequencing will be more accurate in the identification of copy number variants and repetitive sequences. 39. Data from copy number variation and single gene association studies support shared genetic mechanisms causing schizophrenia and autism. 40. This results in four daughter cells with an unpredictable complement of chromosomes, but in the normal copy number .
