nucleus structure and function animation : cell biology






Cell nucleus:  nucleus id the most important organelles in
cell. All the metabolic process occur in cell and the most important thing the
genetic material DNA which are present in in nucleus. All the heredity material
which are comes from parents all these are present in cell. Robert brown give
us more information about nucleus. He study the nucleus by microscope and
absorb that the nucleus have the power to replicate at self in 1838.
Structure of nucleus:   nucleus are divided into 3 parts
  1. Nuclear envelop
  2. Chromosomes
  3. Nucleolus
Nuclear
envelop consist of two membranes  inter
membrane and outer membrane these two membrane same like plasma membrane which
protect the genetic material from the cytoplasm.
Chromosomes
are made up DNA and histones and all the parents character inside the
chromosomes and variation occur inside the chromosomes. The most top field of
the biological science
Nucleolus
present inside the nucleus and helps on transport of mRNA and proteins.
The
most denser organelles in cell. And the most important organelles in cell
All
the metabolic reaction occur in it.

Fundamental biological molecules

Image
To know about the fundamental of biological molecules you mast know about the molecule. What is molecule? All mater is made of chemical atom for example carbon hydrogen oxygen. When atoms combine to form molecule. For example, H2O (water) when two hydrogens and 1 oxygen combine with each other with specific bond called one molecule of water. Now the fundamental of biological molecules. biological molecule is molecule that is present in living organisms, including large macromolecules such as proteins, carbohydrates, lipids, and nucleic acids, as well as small molecules such as primary metabolites, secondary metabolites, and natural products. All these are organic molecule organic molecules are those molecules which have carbon in their structure and play a work like backbone in their structure. Now biomolecule is different from one another in their structure and function of living body. We study basic thing about these molecules and we will talk more about these molecules ...
