Biotechnology labs work with cells and perform much of their research and development using cells. The potential within biotechnology is endless due to the millions of organisms that can be used in biotech research. One of the organisms that are used in biotechnology is the cell. A cell is the smallest part of life that makes up all living organisms
It is very important for anyone who will work in the biotech field to have a clear understanding of cells. There are some organisms that are only made up of one cell. However, plants are often made up of billions of cells. In biotechnology, animal and plant cells are studied and grown in mass quantities in labs. Most employees of biotech companies will need to work with cells at some point. That is why it is very important to understand the function and structure of cells.
One single cell is extremely small. It is less than a tenth of the size of the period at the end of this sentence. Although a single cell is small, it is very powerful. Every minute inside a cell thousands of molecules are being produced.
It is the molecules inside of cells that make each cell so useful in biotechnology. Scientists in biotechnology work on identifying a molecule inside of a cell that can be applied to a specific area. Once identified, they produce or grow billions of that cell in bioreactors. When cells are grown in this way it is called bioprocessing.
The structure of cells can vary between plants or animal cells. Even the cells within plants can be different. Plant cells have a stiff cell wall. A cell wall is an organelle that surrounds a cell. A cell wall offers support around the boundary of a cell. Cell walls are made up of stiff cellulose fibers. Dietary fiber is made partially of cellulose.
An organelle is a microscopic part inside of a cell that has a specific job. Some cells have many organelles, while others have very few organelles. Some of the types of organelles found in cells are chloroplasts, lysosomes, ribosomes, and the nucleus.
All cells have a plasma membrane even if a cell does not have a cell wall. A plasma membrane is a type of organelle that monitors the movement of matter in and out of a cell. At the center of most cells is a nucleus. The nucleus contains controls or instructions for the entire cell to function.
Working with Proteins
Proteins are another important part in biotechnology research. Proteins make up many of the molecules found in cells. Proteins perform many functions inside of cells, such as causing reactions, moving molecules, and offering structural support.
Proteins are often the products that many biotechnology companies manufacture. A single cell will produce thousands of proteins, each with a different purpose.
The proteins in a cell are what do most of the work. The function of each protein is determined by its amino acid sequence. Amino acids are small molecules that make up proteins. In an amino acid sequence, amino acids are connected to each other through peptide bonds
Each pair of amino acids is linked by a peptide bond. A peptide is a short chain of amino acids. When there are enough amino acids linked by peptides a polypeptide strand is formed. This functional polypeptide chain is called a protein.
Even though there are thousands of different kinds of proteins they all have a complex three-dimensional structure. Another characteristic that proteins have in common is the 20 amino acids that make up a polypeptide chain. These chains each have a specific order and length. The three-dimensional polypeptide chain has a specific folding pattern that is determined by the arrangement and number of the amino acids
In biotechnology, it is vitally important to produce and modify proteins or peptides. Almost every biotechnology product involves proteins.
Working with Genes
Within biotechnology, working with genes or DNA is an exciting area. Although most of the research is actually in cells and proteins, working with genes is also a promising area within biotechnology. Both DNA and proteins are molecules that in part make up cells.
The nucleus inside of a cell contains controls or instructions for the entire cell to function. The instructions inside the nucleus are the DNA. DNA stands for deoxyribonucleic acid, which is a molecule that stores genetic instructions for producing all of the proteins in an organism
The DNA or instructions are contained on chromosomes within the nucleus. Chromosomes are long strands of DNA linked with protein molecules. A portion of DNA on a chromosome that contains the genetic code for a protein is called a gene.
Scientists within biotechnology are conducting gene therapy to treat disorders or diseases. Gene therapy is a process to treat a disorder or disease by taking an abnormal gene and replacing it with a useful gene.
Gene therapy is an area within biotechnology where there is a growing amount of research. Scientists are working to find abnormal genes that cause disease so that people can be treated successfully
Research and development in the area of genes offers much potential for treating many disorders and diseases.
