 Definition Of cell A cell is a structural and functional unit of life, which carries all activities of life. Cells are the main building blocks of complex multicellular organisms. Different cells perform different functions, an organism is the combined sum of activities and interactions of many kinds of cells and of different components of the cell. Modern cell theory is  Cell Theory Features; All organisms comprise one or more cells. All cells arise from preexisting cells. A cell is a structural and functional unit for all organisms. What are Types of cells There are two types of cells are in nature. which are Prokaryotic cells Eukaryotic cells  Prokaryotic cells Typical Prokaryotes (Greek : pro – before; karyon nucleus)  don't have defined nucleus and contain relatively simple structure.They include the bacteria and cyanobacteria. Most detailed studied prokaryotic cell is Escherichia coli. Organisms containing prokaryotic cells called prokaryotes. Characteristics ...

#1 What is Biochemistry Biochemistry is the language of biology. The tools used for the research in all kinds of medical sciences are dependent on principles of biochemistry. Definition of Biochemistry • It is the chemistry of biological process. It deals with the chemical reaction. Such as growth, metabolism, reproduction and heredity etc, As the name indicate biochemistry is the hybrid science. • Biology is the science of living organism and chemistry is the science of atoms and molecule in living organism. • It is the science in which chemistry is implemented to the study of living organism and the atoms and the molecules which comprise the living organism. • Biochemistry is the chemistry of life. It include sciences of: • Molecular biology • Immuno chemistry • Neuro chemistry • Bioorganic chemistry • Biophysical chemistry • Biochemistry helps us in Understanding our biology at molecular level. It is very useful in biomedical and agricultural research. Biochemistry has m...

 BALANCED DIET A balance diet is a diet which, along with water, contains all the five types of dietary ingredients i.e. carbohydrates, proteins, fats, vitamins and minerals in amounts sufficient for normal growth and maintenance of health, depending on the individual's age and sex. COMPOSITION OF BALANCED DIET For a healthy adult, weighing 70 Kg, a balanced diet should provide 2400 to 3000 calories per day.  1g of carbohydrate provides 4.6 kilocalories. lg of fat provides 9.1 kilocalories. lg of protein provides 4.2 kilocalories.   Percentage-wise 60-70% of total energy should come from carbohydrates . 20-35% of total energy should come from fats. 10-15% of total energy should come from proteins. 2. Quality-wise Carbohydrates about 600 g/day. Fats about 50 g/day. Proteins about 100 g/day (0.1g/Kg body Wt. at least). Half of the total protein should come from animal sources. In human diet, fat and carbohydrates can replace cach other within wide limits.

 Introduction to Diabetes  Diabetes is generally defined as “any disorder characterized by excessive urine excretion” There are two types of Diabetes  1) Diabetes Mellitus   2) Diabetes insipidus What is Diabetes Mellitus   Diabetes mellitus is a metabolic disorder of glucose,it is a absolute or relative deficiency of insulin which results in hyperglycemia (increase blood glucose level).  Diabetes mellitus is a common clinical condition and third major cause of death in many developed countries, about 1/5th of individual's above the age of 50, Bearing this disease.   Deficiency of Insulin leads to increased blood glucose level. Thus, due to this high blood glucose, the entry of glucose into the cells is inefficient. Hence, all body cells are starved of glucose. Insulin Dependant Diabetes Mellitus(DDM)  It is also known as Juvenile-onset or Type-I Diabetes Mellitus. There is absolute deficiency of insulin due to viral or auto-immune destr...

Easy and short Difference between RNA and DNA is Here   RNA (Ribonucleic Acid) • RNA is a single stranded structure. It is Present mainly in cytoplasm but some in the nucleus. RNA Contains purines (Adenine and Guanine) And Pyrimidines (Cytosine and Uracil). It Contains Ribose(Sugar) and phosphoric acid. DNA (Deoxyribonucleic Acid) DNA is a double stranded helical structure. It is Present mainly in the nucleus but some in the cytoplasm. it is Contains purines (Adenine and Guanine). And pyrimidines (Cytosine and Thymine). It Contains DeoxyRibose (Sugar) and phosphoric acid.

 RNA(Ribonucleic Acid) It is a single stranded polynucleotide.  By the action of RNA polymerase it is made in nucleus from one strand of DNA. protein synthesis is the primary function of RNA. RNA consists of nitrogenous bases, either purine (adenine or guanine) or pyrimidine (cytosine or uracil), sugar. (ribose) and phosphoric acid. Thymine (pyrimidine) is never pres- ent in RNA. There are three kinds of RNA 1.e. messenger  RNA (mRNA), transfer RNA (tRNA) and  ribosomal RNA (rRNA). mRNA takes the message from DNA to tRNA. Just one strand of DNA serves as a tem- plate for the synthesis of mRNA. tRNA also called soluble RNA (sRNA) reads the message and transfers amino  acids to the proper site on the rRNA. rRNA in ribosome of the endoplasmic  reticulum, synthesize protein from the  amino acids brought by tRNA.
