What are topics in molecular biology?
Molecular biology is the study of the structure function, and makeup of the molecular building blocks of life. It focuses on the interactions between the various systems of a cell, including the interrelationship of DNA, RNA and protein synthesis and how these interactions are regulated.
How is molecular biology used today?
Disease prevention and treatment, generation of new protein products, and manipulation of plants and animals for desired phenotypic traits are all applications that are routinely addressed by the application of molecular biology methods.
What are three applications of cell biology?
Biotechnology uses techniques and information from cell biology to genetically modify crops to produce alternative characteristics; to clone plants and animals; to produce and ensure high quality food is available at lower costs; to produce purer medicines and in time organs for the many people who need transplants.
Why are you interested in molecular biology?
The reason why research in molecular biology is so important is because the concepts discovered in this manner can be applied to mainstream biology, medicine, wildlife study and protection of endangered animals, food industry, pharmaceutical industry and environment protection.
Why is PCR an important technique for molecular biologists today?
Polymerase chain reaction (PCR) – This is one of the most important techniques used in molecular biology and is basically used to copy DNA. PCR allows a single DNA sequence to be amplified into millions of DNA molecules. In addition, PCR is used to determine whether a certain DNA fragment exists in a cDNA library.
Why do we use PCR to study DNA?
Using PCR, a DNA sequence can be amplified millions or billions of times, producing enough DNA copies to be analyzed using other techniques. For instance, the DNA may be visualized by gel electrophoresis, sent for sequencing, or digested with restriction enzymes and cloned into a plasmid.
What is importance of molecular biology?
Molecular biology also plays a critical role in the understanding of structures, functions, and internal controls within individual cells, all of which can be used to efficiently target new drugs, diagnose disease, and better understand cell physiology.
