This was believed to be true for hundreds of years....
Answer:
Carbon is the most important element to living things because it can form many different kinds of bonds and form essential compounds.
Believe this ITS CARBON NOT OXYGENNNNN
Answer:
Some forms of chromatin modification can be passed on to future generation of cells
Acetylation of histone tails in chromatin allows access to DNA for transcription
DNA is not transcribed when packaged tightly in a condensed form
methylation of histone tails can promote condensation of the chromatin
Explanation:
chromatin modifications that can be passed on includes epigenetic modifications that are heritable changes made to the chromatin structure that does not involve the DNA sequences. Some epigenetic modifications include DNA methylation and Histone modifications. examples of histone modification include acetylation, methylation, phosphorylation, ubiquintylation etc. All these function either in allowing the DNA become more accessible to transcritional factors or vice versa. for exmple, histone tail acetylation encourages unwounding of nucleosomes allowing transcriptional factors to have access to the DNa while histone tails methylation further tightens the nucleosomes promoting condensation of the chromatin.
Answer:
Cell biology is a branch of biology that studies the structure, function and behavior of cells. All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. Cell biology is the study of structural and functional units of cells.
The answer is muscle weakness, fatigue and dysrhythmias. The distinctive indication of hypokalemia contains muscle faintness, leg spasms, fatigue, paresthesia and dysrhythmias. Indicators of hypercalcemia contain nausea, vomiting, constipation, bone pain, too much urination, dehydration, misperception, weariness and indistinct speech. Reduced cognitive capability and hypertension may outcome from hyperchloremia in which constipation is a indication of hypercalcemia.
