Chromatin definition the readily stainable substance of a cell nucleus consisting of DNA RNA and various proteins that forms chromosomes during cell division. The total DNA in the cell is about 5 to 6 feet long which has to fit inside the nucleus of a cell in an orderly fashion. The correct answer is In prophase I tetrads of homologous chromosomes form and crossing over occurs.

Nuclear membrane Answer is A. DNA is associated with proteins to form _____. They chemically modify the DNA changing the affinity between the histone octamer and the.

After separation each chromatid can be called as a chromosome. Which of the following best describes how chromatin modifications are passed to the second copy of the genome following DNA replicationAn explanation on the explanation doc is not required for this question. 2 Chromatin blob identification and characterization of imaged and modeled chromatin.

DNA molecules first wrap around the histone proteins forming beads on string structure called nucleosomes. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus. Which of the following best describes the authors purpose in the passage.

Chromatin is the association between DNA and proteins called histones. The nucleus was carefully isolated and the chromatin obtained. Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division.

Two copies of each of the following proteins. Heterochromatin is highly condensed because in that state the union between DNA and proteins is very strong and they are very close. Chromatin is a genetic material or a macromolecule comprising of DNA RNA and associated proteins which constitute chromosomes in the nucleus of an eukaryotic cell.

The fibers had a beads on a string appearance suggesting some type of histones Following digestion with micrococcal nuclease protein removal and gel electrophoresis DNA fragments were obtained that are multiples of 280 base pairs.

Chromatids behave as chromosomes. Which of the following best describes the chromosome composition of the mother cell in the G2 phase. Chromatin is DNA the associated proteins so pertains to genetic material.

What is 63 divided by 56. Euchromatin is less compact because in that state the union between DNA and proteins is weak and they are less stuck together. The term chromatin would be used in reference to which of the following.

The term chromatin would be used in reference to which of the following. They use energy derived from ATP hydrolysis to change the relative position of the DNA and the core histone octamer. When mutated proto-oncogenes become oncogenes alleles that inhibit cancer by halting the cell cycle.

Mitosis is a type of cell division at which one parent cells produces two daughter cells with identical genomic content and with the same number of chromosomes as the parent. After a mitotic division is complete a daughter cell has 40 chromosomes. 2 Cells and Tissues.
