In this article, we will discuss about the discovery of nucleus in the cell that contains mostly of the genetic material. This discovery revolutionized the field of modern biological sciences. Before the discovery of nucleus, cell was considered as hollow object. But it was rejected by Robert Brown in 1830.
In this article, we will discuss about the chromosomal mutations that manipulate the functions of several genes. Several types of mutations in the chromosomes causes different disabilities, such as mutation in chromosome number 7 causes blue monochromacy (blue color blindness). We will also discuss the implications and effects of these mutations.
In this article, we will discuss about the process of DNA replication, that reveals the blueprint of life. In the DNA, there is origin of replication from where replication starts. In prokaryotes, only one origin of replication is present. For instance; replication region in yeast is called OriC., that is composed of several short repeated sequences. In eukaryotes, several origin of replication are present.
DNA fragmentation and analysis play a crucial role in understanding the genetic code and its implications in various fields such as medicine, forensics, and evolutionary biology. By studying the fragmentation patterns and analyzing the DNA sequences, scientists can gain valuable insights into genetic disorders, identify individuals, and trace evolutionary relationships.
The discovery of chromosomes stands as one of the most significant milestone in the field of biology. These thread like structures, found within the nucleus of every living cell, contain the genetic information that determines an organism’s characteristics. This groundbreaking revelation has revolutionized our understanding of genetics, heredity and the fundamental mechanism of life itself. In this article, we will dive into the history of discovery of chromosomes, highlighting the key milestones and the scientists who played vital roles in revealing the complexities of life.
