For example, if all of the DNA molecules in a single human cell were unwound from their histones and placed end-to-end, they would stretch 6 feet. Chromosome means: chroma - colour; some - body) A chromosome is a thread-like self-replicating genetic structure containing organized DNA molecule package found in the nucleus of the cell.

The currently accepted concept of chromosome structure proposes that a chromosome in the G 1 stage of the cell cycle has one long DNA double-helix backbone that extends without interruption from one end (telomere) through the centromere to the other end. Chromosomes (Gr., chrom=colour, soma= body) are the rod shaped, dark stained bodies seen during the metaphase stage of mitosis when cells are stained with a suitable basic dye and viewed under a light microscope. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. In the interphase stage the chromosome is made of long thin chromatin fibre. relationship between genome structure and function. 0000015566 00000 n During interphase of the cell cycle, the chromosome exists in a loose structure, so proteins can be translated from the DNA and the DNA can be replicated.During mitosis and meiosis, the chromosome becomes condensed, to be organized and … A chromosome is a long DNA molecule with part or all of the genetic material of an organism.

Some chromosome possess a small fragment or knob like structure called satellite.Such chromosomes are known as SAT chromosomes.The terminal regions on either side of the chromosomes are known as telomeres.The chromosomes consist of about 40% DNA and about 60% histones (a particular type of protein)..

For example, if all of the DNA molecules in a single human cell were unwound from their histones and placed end-to-end, they would stretch 6 feet. Chromosome means: chroma - colour; some - body) A chromosome is a thread-like self-replicating genetic structure containing organized DNA molecule package found in the nucleus of the cell. Chromosomes in the extended and active phase may contain nonhistones and also histones, whereas the stage of inactivity and condensation has been marked by the presence of histones mainly.

The currently accepted concept of chromosome structure proposes that a chromosome in the G 1 stage of the cell cycle has one long DNA double-helix backbone that extends without interruption from one end (telomere) through the centromere to the other end. Chromosomes (Gr., chrom=colour, soma= body) are the rod shaped, dark stained bodies seen during the metaphase stage of mitosis when cells are stained with a suitable basic dye and viewed under a light microscope. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. In the interphase stage the chromosome is made of long thin chromatin fibre. relationship between genome structure and function. 0000015566 00000 n During interphase of the cell cycle, the chromosome exists in a loose structure, so proteins can be translated from the DNA and the DNA can be replicated.During mitosis and meiosis, the chromosome becomes condensed, to be organized and … A chromosome is a long DNA molecule with part or all of the genetic material of an organism.

A chromosome is a structure that occurs within cells and that contains the cell's genetic material. Without such packaging, DNA molecules would be too long to fit inside cells.
