The Y chromosome is one of two sex chromosomes in therian mammals including humans and many other animalsThe other is the X chromosomeY is normally the sex-determining chromosome in many species since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproductionIn mammals the Y chromosome. Approaches to observing the details of single-molecule interactions fall into categories based on the detection method Many are fluorescence-based single-molecule optical biosensors 25 although other specialized physical techniques have been used including electrochemical sensors 6 7 plasmonic sensors surface-enhanced Raman.

Double Helix

This is perhaps not surprising once one realizes that the structure and chemistry of each protein has been developed and fine-tuned over billions of years of evolutionary history.

. From a chemical point of view proteins are by far the most structurally complex and functionally sophisticated molecules known. Although most DNA is packaged in chromosomes within the nucleus mitochondria also have a small amount of their own DNA. We start this chapter by considering how the location of each amino.

This genetic material is known as mitochondrial DNA or mtDNA. In humans mitochondrial DNA spans about 16500 DNA building blocks base pairs representing a small fraction of the total DNA in cells.
