Though the earlier concept of cell theory focused on the basic information about the cell, but the recent concept on cell theory is elaborated by defining the importance of DNA in a cell and Energy flow system of cell. Overall, cell theory explains the structure, working and function of different cells in a living body. Though many scientists and Biologists worked on this theory, but it was Charles Darwin who first provided the world some interesting examples to prove the Evolutionary theory of natural selection.
The key concept of this theory is that species are produced in large number. But environment select only those species that can survive environmental consequences and possess heritable trait that serve advantage for their survival. The study conducted by George Mendel on pea plants was the first insight on gene theory.
His experiments and findings concluded that it is gamete that is involved in transmission of characteristics. Hence, In Gene theory gene is described and proved as a unit of inheritance. Hence, time and again with new findings and results, changes were made in gene theory. The word homeostasis was first coined by cannon. This theory of Biology includes the detail study of endocrine system and nervous system of brain. It comprise of pH balance, blood pressure, electrolyte and many more.
We have appointed best Biology tutors to help you with your Biology projects. In school and Universities; a Biology student need to attend theoretical as well as practical classes. Remembering core concept of every topic along with terms that are specifically used in Biology turns out to be a tiring job. So, our online Biology tutors will help you get over this problem. They are experts having Masters and PhD.
Degree from a well-known University. They also have years of teaching experience. So, they possess immense knowledge on every topic of this field. Hence, your Biology assignment will carry all the minor details of the topic. Our online Biology experts have made a list of few important areas of this field. Some of them are briefly explained below:. Anatomy means the study of internal parts of a living body. The study on anatomical part that can be easily viewed by naked eyes is segmented under gross anatomy and those parts that form the basic organization of a living body is studied under Histological section.
This area of study is important to discover the functioning, composition and importance of any specific part or organ.
Hence, when plants anatomy is studied, it is termed as plant anatomy. Likewise, anatomical study of animals is termed as animal anatomy. Cell is the foundation of any living body. It is the first step for the beginning of life. Though it is minute and cannot be seen by naked eyes, but it is made of many important components.
Hence, knowledge on cell, its structure, composition and function can be obtained by study of Cell Biology. Presently, cells are also important to conduct study on different diseases, transplantation of organs, immune system of body and many more.
It is the area of biology that elucidates our knowledge on living organism at a molecular level. It also provides information on the interaction of different systems of a body at molecular level. Hence, molecular biology is connected with many other fields of Science including Cell Biology, Genetics etc. Some important topics segmented in this field of Biology are Biomolecules, Gene expression, Membrane Biology.
Genetics include the study of gene, heredity and variation of an organism. The reason for transmission of trait, genetic disorders, Study on Chromosomes and DNA are sliced in this field of Biology.
Presently, with the concept and ideas of this field, people have started modifying animals and plants to obtain maximum benefit. Hence, this field of Biology include wide range of topics like genetic engineering, Epigenetics, Molecular genetics and many more. Microbiology deals with the study of minute organism or smaller organism that cannot be viewed by our naked eyes. Are you sure you want to delete this answer? This similarity of proteins between closely related species reflects the evolutionary pattern.
For instance globulin protein present in the red blood cells of human is very similar to those of chimps and very similar to that of a mouse though is more similar to the chimp one, however is not very similar to that of a lizard for instance.
For instance there are just 4 types of nucleotides GCAT while there are 20 amino acids, this means that if you want to translate from DNA to Protein you need some kind of code, this code happens to be in triplets e. Phenylalanine can be translated from either UUU or UUC this all means that if it occurs a mutation substitution kind in the last nucleotide, and U is switched for C then it will not have any effect in the resulting protein, even though technically both DNA sequences are different.
The DNA code should be different for everyone especially between different species. The rest is non coding that is located between the codons.
Before the proteins are made these non coding regions are eliminated. They have names but i forgot sorry. I dont think that slight differences in DNA sequences will give you exactly the same insulin it could be close but the amino acid chain is going to be determined by the order of the DNA so if there is one section of DNA that is not right you will get a different amino acid chain. Amino acids are made up of hydrogen, carbon, oxygen, and nitrogen.
Some examples of amino acids are lysine, phenylalanine, and tryptophan. This goes back to the whole common ancestor thing. Once, humans and cows could have originated from a common ancestor that produced the same or similar chain of amino acids that form insulin.
Those that survive to reproduce are considered the most fit. The cell is checked, making sure that everything is ready for active division 25 c. Molecules move from an area of higher concentration to lower 27 b. James Watson and Francis Crick 31 c. Amino acids 32 c.

Jan 07, · 1. The DNA sequence is differnt for a cow and human, but the amino acid chain produced by the sequence is almost the same. How can this happen? 2. Could two humans or two cows have some differences in the DNA sequence for insulin, yet still make exactly the same insulin proteins? Explain.
