The odds of having a child with a chromosome disorder/syndrome is 1 in 160 live births. (.00625%). Approximately half of these births will end up being a miscarriage. . The final cell suspension in 3:1 methanol:acetic acid fixative was then dropped from varying heights: 0 cm, 1 cm, and 30 cm. A ringstand holding a micropipetter was used to set the height of the cell suspension above the slide and the suspension could then be accurately dropped onto the slide from the appropriate height. 12 µl of cell suspension was dropped onto each slide and the slide was allowed to air dry completely. . The bacterial chromosome is a double-stranded, circular DNA molecule associated with a small amount of protein. Eukaryotic chromosomes have linear DNA molecules associated with a large amount of protein. SUBMITTED BY:. ALABADO, SHEENA ANN C.. LUISTRO, JANELLE. What is a chromosome?. A chromosome is…. A very long DNA molecule and associated proteins that carries portions of the hereditary information of an organism.. Chromatin – the less tightly coiled DNA-protein complex.

Sarah Medland. Boulder 2019. Thinking about sex differences using the language of heterogeneity. Are these differences due to differences in the magnitude of the effects (quantitative)?. e.g. Is the contribution of genetic effects greater/smaller in males than in females?. What is a Chromosome?. A chromosome is a special structure made up of DNA and proteins. DNA is what make us all unique.. The proteins are called histones. They act as spools so the DNA can wrap around it, which is why chromosomes have a peculiar X shape..
