Evolution theory: Evolution theory based on the observation made during the sea voyage by Charles Darwin in sail ship H.M.S Beagle around the world. He was appointed as a naturalist for this voyage to study the vast flora and fauna of the different continents and islands. He said that every living organism, whether animal or […]
Category: Biology
Biology is the study of all living things. In this field of science, we study the functioning of the body, different cells, and organisms.This field is further divided into many other fields such as Bioinformatics, Biochemistry, biotechnology, microbiology.
Polymerase Chain Reaction
Polymerase chain reaction or PCR is developed by Karry Mullis in 1984. This is a method for the amplification of DNA. PCR is based on the capability of DNA polymerase that can synthesize a new strand of DNA that is complementary to the other strand. It is because DNA polymerase can only add nucleotide onto […]
NON-STANDARD AMINO ACIDS
In the previous article on the amino acid, we have studied what is an amino acid and its classification based on polarity. We have also studied what is a peptide bond? How a peptide bond is formed? We know that there are twenty amino acids that help in protein formation and the first discovered amino […]
How to find out the complementary strand of DNA using Python
What is a complementary strand? DNA (deoxyribonucleic acid) is made up of pentose Sugar, nitrogenous bases, and phosphate. DNA has a backbone of sugar and phosphate. As we all know DNA is a double helical structure (Watson & crick model) and both the strand of DNA are complementary of each other. So, what does it […]
EFFECT OF SARS-COV2 ON MALE FERTILITY
CORONAVIRUS: Coronavirus i.e. SARS CoV2 has the origin from china as China reported its first case on 31st December coronavirus causes infection in the lungs causes pneumonia, through this the oxygen supply to the tissues and organs decreases as the lungs get filled with the fluid the alveoli functioning gets disturbed and the gaseous exchange […]
Introduction to molecular diagnostics
Diagnostics: Diagnostics of a disease is a critical and integral part of our health care system. Diagnostics is testing, and these tests inform us about a wide range of medical decisions to be taken according to the disease. Diagnostics tests provide critical insights at every stage of medical care prevention, detection, diagnostics therapy, and successful […]
Fasta format and Sequence comparison
What is fasta sequence? Fasta is a format used to represent nucleotide sequences or protein/peptide sequences. In the fasta format, the sequences are represented with their single letter code. E.g., for nucleotides A, T, G, C, U For proteins: A, M, D, etc. The fasta sequence of any nucleotide or peptide begins with a single […]
THEORIES OF ‘THE ORIGIN OF LIFE’
Theory of special creation- This states that life was created by supernatural power in the form which has not undergone any changes. It was given by FATHER SUAREZ. God created life in six days from Materia prima and man was created on the sixth day. According to this theory, the earth is about 4000 years […]
what is evolution?
WHAT IS THE MEANING OF EVOLUTION? All the life forms that we see around us like plants, animals, or microorganisms comprise the biodiversity on earth. These all life forms have a long history of changes and the study of the history of life forms on earth is called Evolutionary biology. Evolution in simple language is […]
BACTERIAL GROWTH
Bacterial growth is an increase in the cell in cell mass and cell number. Bacterial Growth Curve: under favorable conditions bacterial population doubles at regular intervals. When a fresh medium is inoculated with cells and the bacterial population growth is monitored over some time, plotting data between growth and time leads to a typical bacterial […]
