Group of answer choices. A novel DNA is a new DNA that is being introduced into a cell where it is originally not present.
Cell Chromosome Dna And Gene Cell Structure The Dna Molecule Is A Double Hel Sponsored Structure Molecule Do Dna And Genes Dna Molecule Chromosome
A There will be sufficient old histones in the vicinity of the new histones which dictate which modifications these new histones should.
. As such option C best describes this. Which of the following best describes euchromatin and gene expression. C The cells show characteristics of tumors.
The DNA is loosely compact and transcription occurs easily. H2A H2B H3 AND H4. The DNA is tightly compact and transcription occurs easily.
A The cells are unable to form spindle microtubules. Analysis of the DNA component by gel electrophoresis would have revealed. The correct option among all the options that are given in the question is option A.
Which of the following describes chromatin. They chemically modify the DNA changing the. Chromatin is a substance that contains DNA and proteins within a chromosome.
Which of the following describes what happens during meiosis of humans the best. They use energy derived from ATP hydrolysis to change the relative position of the DNA and the core histone octamer. In prophase I tetrads of homologous chromosomes form and crossing over occurs is the statement among the following statements that best describes the major difference between prophase I of meiosis and prophase of mitosis.
Which of the following helps. Heterochromatin is highly condensed because in that state the union between DNA and proteins is very strong and they are very close. Euchromatin is less compact because in that state the union between DNA and proteins is weak and they are less.
Which of the following best describes the mechanism by which chromatin- remodeling complexes loosens the DNA wrapped around the core histones. Heterochromatin is highly condensed because in that state the union between DNA and proteins is very strong and they are very close. The transfer of novel DNA into a cell.
This problem has been solved. A tightened structure of DNA. DNA tightly coils around proteins and condenses into chromosomes which fit in the nucleus.
Chromatin is the association between DNA and proteins called histones. DNA is double-stranded so one strand is inside the nucleus and the other wraps around the nucleus. ODNA is naturally much smaller than the cell nucleus so it easily fits inside the nucleus.
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. Two copies of each of the following proteins. A group of DNA outside of the nucleus.
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 statements best describes ribosomes. Transformation describes procedure which involves the introduction as well as expression of foreign genes in a host organism.
The transfer of novel DNA into a cell. A Ribosomes guide protein synthesisB Ribosomes are found only in the nucleus or on the RER. The correct answer y C.
An egg 1n gets fertilized by a sperm 1n to form a fertilized egg that has. A loosened form of a chromosome. Another constituent of the chromatin is the material that carries the genetic information of an organism.
Which of the following best describes the term chromatin. Chromatin is the association between DNA and proteins called histones. The cells start meiosis at 2n4x and end up as 1n1x D.
The DNA is loosely compact and transcription does not occur easily. Which of the following statements best describes cells in culture that do not exhibit either density-dependent inhibition or anchorage dependence. Acetylation of histone tails is a reversible process.
A Ribosomes guide protein synthesis. DNA folds into stacked layers called chromatin which then squeeze into the nucleus. They use energy derived from ATP hydrolysis to change the relative position of the DNA and the core histone octamer.
Euchromatin is less compact because in that state the union between DNA and proteins is weak and they are less stuck together. D Ribosomes are the site of photosynthesis. 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.
A ladder of protected fragments about 200 bp apart. B The cells follow an altered series of cell cycle phases. They chemically modify the DNA changing the affinity between the histone octamer.
Which of the following best describes the role of chaperone proteins in the regulation of gene expression by steroid hormones. E All of the above. Which of the following best describes the mechanism by which chromatin- remodeling complexes loosen the DNA wrapped around the core histones.
D The cells have nonfunctional MPF. There are 92 pieces of chromatin paired as 46 bivalents tetrads in metaphase I of meiosis I C. The primary meiocyte goes from 2n2x to 2n4x and then to 1n2x B.
Some forms of chromatin modification can be passed on to future generations of cells. C There are no ribosomes in the mitochondria. Which of the following best describes the mechanism by which chromatin-remodeling complexes loosen the DNA wrapped around the core histones.
Which of the following best describes the mechanism by which chromatin-remodeling complexes loosen the DNA wrapped around the core histones. Histones are the major proteins in chromatin and they help condense chromosomes to fit into the cell nucleus during cell division.
