Throughout most of the life of a cell, the DNA is only loosely wrapped around the histones and is not in the condensed chromosomal form. The tighter wrapping, or condensing, of the chromosomes occurs only during mitosis, the process of cell division. During mitosis, the chromosomes condense so that each chromosome is a distinct unit. Prior to mitosis, the cell copies its DNA so that it much more packaging; the nucleosomes (DNA wound around histones) and all the scaffolds and higher order packing.

    Not only does chromatin pack up chromosomal DNA, PDF Featured; Last comments from the U.S. have conducted a study on DNA packaging in the cell nucleus and its … 5/10/2011 · Its advantage is that it does not depend on the microscopic details of the DNA chain or on specific DNA–protein interactions. In light of the difference in length scales between proteins and chromosomes, the question has to be raised whether local actions of specific proteins alone are able to globally shape chromosome organization ( 7 , 32 ).

    The packaging of chromosomal DNA plays a critical role in the epigenetic regulation of the whole genome. It ensures effective storage, access to genetic information and its regulation by the complex protein machinery utilised in gene expression. Chromosomal transformation in pneumococcus results from a donor DNA strand segment replacing its homolog in the recipient chromosome. 2. Plasmid transformation, in which part of the plasmid genome is replaced, is similar.

    This total length of the chromosomal DNA is nicely packaged inside the nucleus by special proteins called histones. These DNA and histone complexes are known as chromatin fiber. Histone proteins provide the energy for folding or coiling DNA and packing them tightly inside the nucleus. DNA packaging is a vital process in eukaryotes, and it facilitates the accommodation of total length of DNA Biology 105/Summer 2013 Lecture 12: Eukaryotic Chromosomes 7/25/13 1 of 4 12.1 Chromosomal DNA and Proteins p. 406 12.2 Chromosome Structure and Compaction p. 408

    Chromosomes are made up of long pieces of double-stranded DNA twisted and condensed into a compact package. If left uncondensed, the strands of DNA would be about two meters each, far too long to fit inside your cells. Chromosomal transformation in pneumococcus results from a donor DNA strand segment replacing its homolog in the recipient chromosome. 2. Plasmid transformation, in which part of the plasmid genome is replaced, is similar.

    Throughout most of the life of a cell, the DNA is only loosely wrapped around the histones and is not in the condensed chromosomal form. The tighter wrapping, or condensing, of the chromosomes occurs only during mitosis, the process of cell division. During mitosis, the chromosomes condense so that each chromosome is a distinct unit. Prior to mitosis, the cell copies its DNA so that it the amount of DNA per cell is constant, the amount and kinds of chromosomal proteins differ greatly from one cell type to another. Metaphase chromosomes contain the two DNA molecules (replicated DNA) linked together at a structure called

Coupled with these factors the DNA polymerases that are found in eukaryotes work much slower NOT faster!! At the rate they work it would take 30 days to copy the human genome if it was left to 2 replication forks! The average E. coli replication fork works around the chromosome at a
