What is the role of nucleus in protein synthesis? Ans: The information of DNA of nucleus is transcribed into RNA. This RNA is used in the synthesis of proteins by translation. These proteins in the form of enzymes and other proteins determine the specific activities of the cells. What are perinuclear space and nuclear lamina? Ans: The nuclear envelope is ...

Following are the important questions and answers for cell and its structure. Students can prepare these questions and answers for their test and exams. What are SER? Give their function? Ans: The cytoplasmic surface of the SER lacks ribosomes. So, they are known as SER. SER of various cell types functions in diverse metabolic processes like synthesis of lipids, carbohydrate ...

Following are test question answers for the plasma membrane and cytoplasm. Student can prepare these important question to prepare for any test. Give chemical composition of plasma membrane? Ans: Protein: 60 to 80%, Phospholipids: 20 to 40 %, Cholesterol in small amount, Carbohydrates in small amount. What was the model of E. Gorter and F. Grendel? Ans: They described that ...

The branch of science that deals with plants and animals is known as Biology and the sub branch which deals with the cell structure and their functionalities is known as Cellular Biology. Both structure and function are equally important and one cannot be given precedence over the other. One of the most important aspects that need to be taken care ...

 FUNCTIONS OF CELL Cells are an integral part of any living organism. It is them that collectively form a system which is why; studying their functions is one of the primary things to learn for the humans. Studies have revealed that the cells work in groups and are parts of larger entities known as tissues. Different cells perform different kinds ...

CELL DIVISION PROCESS Reproduction is one of the most important things that a cell has to undergo for most of its lifespan. It is a complex process that is undertaken in multiple steps, one at a time. There is a sequence attached to these steps which are carried out in a manner such that all information (DNA and genetic) along ...

CELL INTRODUCTION Technically, an organism is produced from a single cell. When implanted in the mother’s womb, the cell extracts the necessary nutrients and divides to form new cells which collectively lead to the creation of a body self sustaining in nature. If the hierarchy of the organisms is studied, one may find those composed of a single cell to ...

CELLULAR BIOLOGY – KEEPING THE INTERESTS OF EVERYONE ALIVE Of all the branches of medical science, cellular biology has a special place. This is because even though significant discoveries have been made with it, there is still a lot to be explored and understood. While in some areas, there are results but no explanation, some areas witness theories without any ...

Cellular biology is a stream derived from the combination of biology with technology. It involves a fairly complex study and is mostly seen as one meant for the academics who can devote time for stringent research and development. The study involves understanding the physical and chemical properties of the cells present in the human as well as the animals that ...

HELA CELLS Cellular Biology has been given a big boost with Hela Cells. Its origin can be traced to the 1950s when it was extracted from a lady named Henrietta Lacks in Africa. This cell has been able to provide a major breakthrough in the lives of millions worldwide. Polio, a disease which had to be eradicated from the face ...
