LIFESCIENCE MAJORS

Various departments make up the life science category. They are explained in the note below.

LIFESCIENCE Or the science of life.

Life science is the branch of science that studies living organisms and their life processes.

This branch of science combines both theoretical and practical knowledge of biological processes occurring in living organisms.

MAJORS IN LIFE SCIENCE

Here, we will examine five major disciplines that make up the life science department. They are:

1. Botany
2. Biology
3. Zoology
4. Biochemistry
5. Microbiology
6. Genetics
7. Molecular biology
8. Cell biology

Each of these disciplines has its critical role in examining biological processes that occur in a living organism.

They sometimes work independently of each other but always tend to one thing – helping living creatures. Let’s explain each one of these disciplines:

1. Botany – This is the scientific study of plants, their physiology, structure, genetics and classification
2. Biology – This is the branch of life science that encompasses the study of the structure, evolution and function of living organisms (plants and animals).
3. Zoology – This field studies the behaviour, physiology and classification of animals.
4. Biochemistry – Biochemistry is a discipline that studies biological processes within and relating to living organisms
5. Microbiology – This is the study of microorganisms and their impact on human health.
6. Genetics – This refers to the scientific study of genes, heredity and the variation of inherited traits.
7. Molecular biology – This aspect examines biological activities at the molecular level, including DNA, RNA, and protein synthesis.
8. Cell biology – This is a branch of biology that focuses on the study of cells, the fundamental structural and functions and interactions.

TERMINOLOGIES USED IN A LIFESCIENCE ENVIRONMENT

Quickly, let’s see some important words that you probably need to add to your vocabulary if you have an aspiration in the life sciences direction.

Basic terms like cell, DNA, RNA, protein, genome, mutation, enzyme, metabolism, and chromosome are a must-use.

Words such as genotype, nucleotides, transcription, gene expression, antibody, antigen, and buffers help yield productive conversations.

PROCEDURES FOR A LIFE SCIENCE LABORATORY

Of course, we want to observe basic and advanced procedures carried out in a life science laboratory.

Some basic ones are:

• Centrifugation to separate cell components

• Spectrophotometry for measurement of absorbance
• Gel electrophoresis

• Polymerase Chain Reaction (PCR)

 

More advancedly, a few other life science procedures include:

• ELISA (Enzyme-Linked Immunosorbent Assay)
• CRISPR/Cas9 Gene Editing
• Next-Generation Sequencing (NGS)
• Protein identification and quantification
• High Performance Liquid Chromatography (HPLC), Gas Chromatography (GC) for separating compounds or proteins
• Real time PCR or Quantitative PCR

WHAT DOES IT BRING TO THE TABLE?

Finally, the lifescience aspect is a major help to the health sector.

• Molecular Biology has helped in the identification of biomarkers to help in the early detection and monitoring of diseases like cancer and cardiovascular conditions through research on the genetic basis of diseases.
• Life science plays a key role in the rapid development of vaccines.
• Integration of biological data with AI and big data analytics through biotechnology supports better clinical decision-making and research.
• Early diagnosis and personalized treatments cut long-term healthcare costs by preventing health complications.

The life science caetgory is a broad field that ultimately aims to provide improved and efficient health systems while laying the groundwork for further research.
