Nature has created many beautiful masterpieces, but a butterfly is the most beautiful and colorful masterpiece. The vivid colors of butterfly wings are so life like that sometimes people call them “flying flowers”. Do you know, these colorful creatures actually belong to the insect family of the animal kingdom. Here are some amazing facts about butterflies that may surprise you.
The Pituitary Gland is located in a bony cavity called Sella turcica and is attached to the hypothalamus by a hypophyseal or infundibular stalk in front of the pons. It consists of three lobes: Anterior lobe, Intermediate, and Posterior Lobe. These three lobes produce nine different types of pituitary hormones. Continue reading What are various Hormones produced by Pituitary Gland?
DNA is the genetic material in all except certain viruses. In Prokaryotic cells, DNA occurs in the cytoplasm and is the only component of the chromosomes. Whereas, in Eukaryotic cells, DNA is largely confined to the nucleus. Do you know, A human DNA contains 3 billion chemical letters. Yes, it is true. There are several other amazing and fun facts about DNA that we don’t know.
In recent times, the people of India have been heard talking about gene sequencing, gene editing, gene sequencing, and many other similar terms. It seems like, they are now getting introduced to the idea and principle behind personal genomics. Continue reading Personal Genomics: Gene Sequencing & Analysis in India.
The cells of an embryo get their roles when they are capable of differentiating autonomously in a neutral environment such as a petri dish or test tube. (the environment is neutral with respect to the development pathway.) This process of giving different roles to embryonic cells is called Cell Specification. Continue reading How do cells in Embryo get their Roles to Play?
In 1868, T. H. Huxley described protoplasm as the “physical basis of life”. Protoplasm is a clear, colorless and jelly-like substance which seemed to make up the contents of the cell. It was also described as “substance of life” or “living material”. Continue reading What is the physical basis of life?
A most common and important source of genetic variability is known to be present uniformly throughout the genome is termed Single Nucleotide Polymorphisms or SNPs. Interest in SNPs lies in the fact that these polymorphisms may be responsible for the differences in disease susceptibility, drug metabolism and response to environmental factors between individuals. Even, if they are not directly responsible for the disease, they serve as genetic markers for a nearby locus that might be responsible. Continue reading What are SNPs? Why are Scientists interested in them?
An average Human cell (diploid) contains about 6.4 billion base pairs of DNA divided among 46 chromosomes. The length of each base pair is about 0.34 nm. Therefore, if the DNA molecule in a diploid cell were laid out end to end, the total length of DNA would be approximately 2 meters. Continue reading How a 2 meters long DNA is fitted into a 2 micrometers Nucleus?
