What is the nucleus in eukaryotes for? Telomere shortening and cellular senescenceNo abstract is available for this article.doi:10.1016/S0248-4900(00)88210-6Alexey M OlovnikovJohn Wiley & Sons, Ltd.Biology of the Cell
In cell biology, the nucleus is the large, membrane-bounded organelle that contains the genetic material in the form of multiple linear DNA molecules organized into structures called chromosomes. In cell biology, the nucleus function is to act asthe control center of the cell. What is the term...
So, the correct answer is A.Note:Genes are contained in chromosomes. These in the cell nucleus. A single chromosome contains hundreds to thousands of genes. Every normal human cell comprises 23 pairs of chromosomes that mean a total of 46 chromosomes. A trait is any gene...
Since the atomic mass of Sodium is 23, we can also write it as 23 g/mol.Therefore, we conclude that Option B is the correct answer.Additional Information:The atomic number of a chemical element is the number of protons found in the nucleus of every atom...
{{B}}Text 2{{/B}}What can be inferred from the last paragraph A.Whether or not to have a nucleus is important in biology.B.The speaker will tell us how to distinguish bacteria tomorrow.C.Evolution will be the main topic of the program next time.D.Eukaryotes develop from prokaryotes...
This question may seem silly, but I always wanted to know the answer to it. If a person has a photographic memory, or some other exceptional memory ability, is it because their caudate nucleus is bigger than the average person's?
to form structures calledchromosomes. Each chromosome contains a single DNA molecule, wrapped tightly around spool-like proteins called histones, which provide chromosomes their structure. Humans have 23 pairs of chromosomes, which are found inside each cell's nucleus, the control center of the cell...
If the DNA within a cell is not separated from the cytoplasm, then that cell is a prokaryote. All known prokaryotes, such as bacteria and archaea, are single cells. In contrast, if the DNA is partitioned off in its own membrane-bound room called the nucleus, then that cell is a ...
