Which of the Following Best Defines Chromatin

A large value of Km tells us that an enzyme shows little specificity for a given substrate. DNA or RNA and proteins eg.

Cell Nucleus

A small value of Km tells us that an enzyme binds strongly to its substrate.

. A They use energy derived from ATP hydrolysis to change the relative position of the DNA and the core histone octamer. 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. Km is the concentration of substrate at which the rate.

Chromatin is the association between DNA and proteins called histones. This quiz and worksheet will test you on. They use energy derived from ATP hydrolysis to change the relative position of the DNA and the core histone octamer.

A ladder of protected fragments about 200 bp apart. Another constituent of the chromatin is the material that carries the genetic information of an organism. When the chromatin is very condensed it is known as heterochromatin.

55 Which of the following statements describes chromatin. If your technique is good youll see this. Euchromatin is less compact because in that state the union between DNA and proteins is weak and they are less.

There will be a clearly defined nucleus 2 with a dark spot the nucleolus often visible. Analysis of the DNA component by gel electrophoresis would have revealed. A Heterochromatin is composed of DNA whereas euchromatin is made of DNA and RNA.

A There will be sufficient old histones in the vicinity of the new histones which dictate which modifications these new histones should. The chromatin has to be able to change form to some extent in order for transcription of DNA to occur. Quiz Worksheet Goals.

Two copies of each of the following proteins. Changes in chromatin structure are associated with DNA replication and gene expression. This problem has been solved.

A Heterochromatin is composed of DNA whereas euchromatin is made of DNA and RNA. What is the best definition of chromatin. Chromatin is the association between DNA and proteins called histones.

Heterochromatin is highly condensed because in that state the union between DNA and proteins is very strong and they are very close. Which of the following best describes the mechanism by which chromatin- remodeling complexes loosen the DNA wrapped around the core histones. H2A H2B H3 AND H4.

Chromatin is the association between DNA and proteins called histones. Asked Oct 5 2016 in Biology Microbiology by Cobra a They use energy derived from ATP hydrolysis to change the relative position of the DNA and the core histone octamer. Which of the following best describes the mechanism by which chromatin-remodeling complexes loosen the DNA wrapped around the core histones.

B Heterochromatin is highly condensed whereas euchromatin is less compact. Group of answer choices. The DNA carries the cells genetic instructions.

Which of the following statements correctly describes the structure of chromatin. Chromatin is a substance within a chromosome consisting of DNA and protein. A typical lab in an introductory college or AP Biology course involves looking at human cheek cells.

Chromatin is a complex of nucleic acids eg. Gene regulation through DNAchromatin packaging. Km is the concentration of substrate at which the rate of the reaction reaches Vmax.

Euchromatin is less compact because in that state the union between DNA and proteins is weak and they are less stuck together. The reason for this arrangement is that it enables the chromatin to easily be packed into the nucleus. Euchromatin is less compact because in that state the union between DNA and proteins is weak and they are less stuck together.

Heterochromatin is highly condensed because in that state the union between DNA and proteins is very strong and they are very close. Which of the following best describes the term chromatin. They chemically modify the DNA changing the.

They use energy derived from ATP hydrolysis to change the relative position of the DNA and the core histone octamer. Which of the following best describes the mechanism by which chromatin-remodeling complexes loosen the DNA wrapped around the core histones. Thus we can define chromatin as a substance consisting of DNA and associated proteins known as histones.

They chemically modify the DNA changing the affinity between the histone octamer. Heterochromatin is highly condensed because in that state the union between DNA and proteins is very strong and they are very close. B Both heterochromatin and euchromatin are found in the cytoplasm.

The major proteins in chromatin are histones which help package the DNA in a compact form that fits in the cell nucleus. Chromatin is a substance that contains DNA and proteins within a chromosome. Examples of what chromatin is like.

C Heterochromatin is highly condensed whereas euchromatin is. The meaning of the word chromatin. The correct answer y C.

Histones are the major proteins in chromatin and they help condense chromosomes to fit into the cell nucleus during cell division. Which of the following best describes the mechanism by which chromatin- remodeling complexes loosens the DNA wrapped around the core histones.
