These chromosomes contain between 20,000 and 25,000 genes. New genes are being identified all the time. The paired chromosomes are numbered from 1 to 22 according to size. (Chromosome number 1 is the biggest.)
WebApr 13, 2024 · Preclinical models like cancer cell lines and patient-derived xenografts (PDXs) are vital for studying disease mechanisms and evaluating treatment options.
