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 […]
Python – Program to find ASCII value of a character
In this post, we will write a Python program for how to find ASCII value. First, let’s see What is ASCII value? In programming languages, the characters (variable) holds ASCII value which is an integer number rather than that character itself is known as the ASCII value of character. ASCII stands for American Standard Code […]
BACTERIAL GROWTH
Bacterial growth is an increase in the cell in cell mass and cell number. Bacterial Growth Curve:Â 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 […]
Python – Program to Find Circumference of a Circle
In this post, we will write a program for how to calculate circumference of a circle in python. First, let’s see What is Circumference of Circle? The perimeter is the curve length around any closed figure. Formula: Circumference of Circle: C = 2 * pi * r Where, r = Radius of circle pi = […]
DNA replication
As we all know every new cell is formed from pre-existing cells. Even a new cell gets its DNA from preexisting cells. In order to fulfill the requirement of DNA for the new cell, DNA must be gone under a process, and multiply this process is known as DNA replication. We all know that DNA […]
TRANSCRIPTION Difference between PROKARYOTES AND EUKARYOTES
Transcription: This is a process in which the information from a DNA strand is copied into messenger RNA (m-RNA). It describes how a DNA Strand is converted into RNA (m-RNA). This is a process of the central dogma. To understand the difference between prokaryotic and eukaryotic transcription first we must know about what transcription is […]
Python – Program to Find Area of a Circle
In this post, we will write a program for how to calculate the area of a circle in python. First, let’s see What is the Area of Circle? The area enclosed by a circle of radius r in 2-dimensional plane. Formula: Area of circle: A = pi * r * r Or pi * r […]
Central Dogma of Molecular Biology
The central dogma is the flow of information (DNA—RNA–Protein). The process of central dogma explains how the DNA is converted into a functional product. It was first proposed by Francis Crick (1957) and published (1958). Central Dogma also confirms that our DNA contains all the information that is required to make proteins. A gene is […]
PLASMIDS
The plasmid is the extrachromosomal DNA that can independently replicate. Most commonly plasmids are found in bacteria as double-stranded circular DNA. Sometime plasmid can be found in multicellular organisms. Plasmid classification: Conjugative and Non-conjugative Plasmid Conjugative plasmids are characterized by the ability to promote sexual conjugation between bacterial cells. Non-conjugative plasmid can’t make sexual conjugation. […]
TRANSCRIPTION
TRANSCRIPTION UNIT- It is the collective term used for all the base pairs present on DNA. It helps in the process of transcription. THESE ARE OF THE FOLLOWING THREE TYPES- PROMOTER- These are the base sequences that initiate the process of transcription and are present at 5’ end of the coding strand. STRUCTURAL GENE- These […]
