It takes the "code" of the Dna bases to the cytoplasm and it attaches to a ribosome. It then gives the "code" to the Transfer RNA. Without MRNA the organism wouldn't be able to go through the process of Protein Synthesis. Therefore it is necessary that MRNA be included in this process!

This used and reused of matter on earth is called the "matter cycle".

Most often mitosis occurs near the apical meristem which is located in the main root tip, at the auxiliary buds and at the very top of the main stem. Mitosis does not occur at the meristems, but usually very close behind them

Captain Hook is the pirate from Peter Pan that captains the Jolly Roger.

Chargaff's rules state that DNA from any cell of all organisms should have a 1:1 ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine. This pattern is found in both strands of the DNA. They were discovered by Austrian chemist Erwin Chargaff.

Fragmentation is a means of asexual reproduction in which a single parent breaks into parts that regenerate into whole new individuals. Starfish use fragmentation and regeneration, the regrowth of body parts from pieces of an animal, to reproduce.

The nucleus of a cell needs several things to function properly. These things are proteins, enzymes, catalysts, and other things as well.

You have 60 % of water in your body. 40% in the intro-cellular compartment and 20 % in the Extra cellular compartment. So it comes to be 40 liters in a 'Average' man weighing 70 kg.It means 28 liters in intro-cellular and 14 liters in extra cellular compartment. Human body has carried with it the part of sea, probably as a extra cellular compartment.Isotonic means that tonicity of fluid equal to body fluid.In extra cellular compartment, Sodium chloride is present mainly. It contains 'about' 150 mili mole of Sodium chloride.One mole of Sodium chloride contains 58.5 gram/liter of it.Mass number of Sodium being 23 and that of Chlorine is 35.5. So added together it makes 58.5 gram/liter. One mole of Glucose contains 180 grams/ liter. (C 6 H 12 O 6 means 126 plus 112 plus 16* 6, it means mass numbers of the respective elements.) (It means 1000 mili mole/liter.) So 9 gram/liter or 0.9 % of sodium chloride or 0.9 gram/100 ml, makes Isotonic saline solution. So Isotonic solution is compatible with 'Human' normal saline solution.It will neither make cells to shrink nor swell. So 0.45 % Sodium chloride solution is Hypo-tonic and 0.9% Sodium chloride with 5 % Glucose solution is Hyper-tonic.(In your body, Glucose will be rapidly utilized to give energy and you get Isotonic saline solution.) Normal saline solution means in which 1 mole of molecules dissolve/ liter and is a term used in chemistry. So when you say Normal saline, it means it contains 58.5 gram/liter of sodium chloride and will kill the patient in no time, after few infusions. So previously human normal saline and then 'Isotonic' saline solution is the correct term to be used. The normal saline solution available in market is not "Normal'. It is 'Isotonic' solut

Yes It Is

Carbon atom, Monomer, Polymer, Macromolecule

These are both used as pH indicators.

It is an enzyme that breaks down Hydrogen Peroxide.

Yes! Bacteria are prokaryotes.

* They don't have organelles * Don't have a nucleus * Small * Replicate by binary fission * Single cell * Often have flagella or cillia to move around

Animal cells are surrounded by a cell membrane.

Insulin operates on those surface (membrane) proteins that transport sugar through the cell wall, not on organelles within the cell.

The centrosome contains centrioles.

A trait is an observable, physical characteristic of an organism (a phenotype). A FACTOR is the underlying genetic cause of the TRAIT (the genotype).

"Nucleoli are made of protein and ribosomal DNA (rDNA) sequences of chromosomes." for more info click on this link (this is where i got the info about nucleolus) http://en.wikipedia.org/wiki/Nucleolus

Both serve to transport molecules across cell membranes and both make use of proteins embedded in cell membrane in order to move these molecules.

Barbara spent years of research and after a very careful study of many generation. In 1944 McClintock recognized Jumping of DNA, which refer to unstable of DNA to move around between the chromosomes. But for many years her theory was disregarded.

In 1983, the theory of jumping DNA or which is known today "Transposable" was confirmed. In 1983 McClintock was awarded The Nobel Prize in Genetics for the discovery of genetic transposition.

Different atoms, particularly carbon, hydrogen, nitrogen and oxygen, made up molecules into such things as proteins, lipids, phospholipids, enzymes, and amino acids. These molecules are part of what makes up a cell, including DNA, and is obviously the first "material" that was first seen in cells.
Cells are made/constructed of many different chemicals, but when were they first seen? In the 1670's, Anton van Leeuwenhoek saw microscopic organisms with a microscope that he had fashioned... but there could have been someone who saw them before that... certainly people who knew of their existence.
