Diagram Of Chromosomes


Diagram Of Chromosomes - diagram of chromosome structure a chromosome is a physically discrete portion of the genome which carries many individual genes eukaryotic chromosomes are posed of chromatin which is a mixture of dna and protein the protein primarily histones acts as a scaffold organizing the structure of the dna which is a long string polymer of nucleotides adenine cytosine guanine and thymine fine structure of chromosomes the condensed chromosomes visible during mitosis are posed of an organized array of chromatin fi 173 bers but in their de condensed state give rise to a highly disperse work fig 20 4 each chromatin fiber is believed to contain one molecule of dna a pair of chromosome refers to the two homologous chromosomes in a diploid individual one chromosome from each set for a given chromosome number in contrast in eukaryotes all of the cell s chromosomes are stored inside a structure called the nucleus.
