prokaryotes and archaea do not. The nucleus is usually the largest organelle present in a cell, taking up about ten percent of the space. The DNA contained in a nucleus is tightly packed into chromosomes, which must
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 ...
What are the organelles inside a cell? Give examples. What is the list of organelles that take part in protein synthesis? List the four organelles that every cell must have. Which of the following organelles contains no DNA? a. Nucleus. b. Golgi body. c. Mitochondrion. d. Chloroplast. ...
The first attempt to create an OS that used a kernel to pass messages was in 1969 with the RC 4000 Multiprogramming System. Programmer Per Brinch Hansen discovered it was easier to create a nucleus and then build up an OS, instead of converting existing OSes to be compatible with new hardw...
The CN cycle begins with the nucleus of a carbon-12 atom using it as a catalyst — an element that speeds up a reaction but is unchanged at the end of it — for fusion. Carbon-12 through proton capture goes through various stages until a helium atom is emitted and carbo...
2. The Cell Is The Most Basic Unit Of Life This one is perhaps the most misinterpreted postulate. Organelles like the nucleus, ribosomes and many more are present inside the cell; they are smaller in size, but vital for the existence of life. If that’s the case, shouldn’t they be ...
But it’s important to note that, in the type of cells that undergo mitosis, the genetic material of the cell is contained within the cell’snucleus.So, while mitosis is often referred to as “cell division,” mitosis istechnicallythe division of a cell’snucleusinto two new, identical n...
The more protons and neutrons contained in an atomic nucleus, the heavier that element is. So, for example, lead has 82 protons and between 120 and 132 neutrons in its nucleus, whereas hydrogen, the lightest element, has just one proton and occasionally one or two neutrons. The number of ...
a. nucleus b. organelles are not found in prokaryotic cells c. mitochondria d. chloroplasts List the organelles found in a eukaryotic cell that are not found in a prokaryotic cell. What are the three organelles found in an animal cell? What would be expected in a cell that on...
Chromosomes are contained within the nucleus in eukaryotic cells, but can also be found in some of the other organelles such as mitochondria (where DNA is packed into a small circular chromosome). In prokaryotes (e.g. bacteria), on the other hand, chromosomes form the nucleoid that is ...
