Answer by Uneekstar. Confidence votes 1. In the interphase nucleus the chromatin exists in two forms; loosely coiled form called euchromatin and tightly coiled form called heterochromatin. These two types become much more coiled to form the chromosome at the time of cell division.Now come to the point.When DNA is a bit loosely colied, that is, in the euchromatin, its bases are available for transcription. On the other hand, when it is in the form of heterochromatin, the bases are not accessible for reading by RNA polymerase, hence transcription is not possible.nswer by Uneekstar. Confidence votes 1.

DNA is the heredity material of the cell. Some cells (bacterial cells) have one large circular DNA strand. In other organisms like us (aka eukaryotic cells) the dna for the cell is in several linear strands instead of one large circular piece of DNA. Each one of these strands of DNA is called a chromosome. The DNA of each chromosome is really tightly wound up around proteins called histones. Finally, a gene is a small segment of DNA, found in a small section of the chromosome (These can often be seen as dark bands in pictures of chromosomes). It is here, at the gene, that the DNA uncoils and opens up momentarily in order to have the gene 'read' and eventually copied into a protein (aka polypeptide).
