WebStaining Techniques. Unambiguous chromosome identification depends on the use of various staining techniques. Staining is responsible for the alternating dark and light bands on the chromosomes noted in Figure 11.1B. The most routinely used technique stains the metaphase chromosomes with Giemsa (after using the enzyme trypsin to digest proteins). WebWe cloned a human protein (Hzyg) homologue to Caenorhabditis elegans Zyg-11, an essential protein for cell division at the initial developmental stages of this species, and to a Drosophila melanogaster gene product (Mei-1) which is likely to be involved in meiosis. Hzyg mRNA encodes a protein of 766 amino acids (88 kDa), 14% of which are leucine …
