· Petite vidéo faite maison pour comprendre ce qu'est l'ADN, les chromosomes et les gènesThe two chromosomes in a homologous pair are generally very similar to one another They're the same size and shape, and have the same pattern of light and dark bands, as you can see in the human karyotype (image of the chromosomes) shown above Bands appear when the chromosomes are stained with a dye, and the dark bands mark more compacted DNA (usually, · organization of DNA in chromosomes 1 ORGANISATION OFCHROMOSOMES 2 INTRODUCTION Chromosomes are the structures that contain the genetic material They are complexes of DNA and proteins The genome comprises all the genetic material that an organism possesses In bacteria, it is typically a single circular chromosome In eukaryotes, it refers to one complete set of nuclear chromosomes

· DNA is the chemical form of storing genetic information for the development, functioning, and reproduction Since DNA is a long strand it should be well packaged within the cell Thus, DNA is condensed with histones to form chromosomes Therefore, the key difference between DNA and chromosome is that a chromosome is the packaging structure of DNA Reference 1 "DNASometimes chromosomes possess single chromatids at times it has two chromatids This is the case with DNA molecules also may be one or two The reason is simple, before replication, chromosome has one chromatid, after S phase or replication The DNA content is doubled So chromosome has two chromatids after replication · Wholechromosome imaging 11,17,18 would be an ideal tool to resolve and characterize the fine structure of chromosomes Unfortunately, such studies suffer from a limited resolution because the
