RNA Translation | The 3 Step Process of Protein synthesis

rna transcription

The translation is a process by which ribosomes present in the cytoplasm (on  endoplasmic reticulum) synthesize the proteins from an mRNA. The RNA Translation occurs by 3 steps like 1.Initiation 2. Elongation 3. Termination. A protein is a polypeptide that has a sequence of the amino acids coded by the mRNA. There are different types […]

DNA Transcription |3 Step Process in mRNA formation

dna transcription

Transcription means a written version of something. So, a DNA transcription means formation of a copy of DNA strand. “The process by which the DNA sequence is read and the complementary RNA molecule is formed is called transcription.” Thus the DNA codes for RNA strand which will then code for the protein. Before transcription can […]

Cell Membrane Transport | 6 Types with Examples

facilitated diffusion

Cell membrane is a delicate organ of the cell which regulates movement of substances into and outside the cell. The cell membrane transport occurs in two major ways like 1. Passive transport Passive diffusion Facilitated diffusion Osmosis. 2. Active transport. Sodium potassium pump Bulk transport (phagocytosis and pinocytosis) Cell Membrane Transport The structure of cell […]

Leaf anatomy | Both Internal and External with Labelled Diagram

Leaf anatomy

Leaves are the main photosynthetic organs of the plant. Anatomy of leaf is the detailed study of internal structure of a leaf, usually revealed by its dissection. Leaves are responsible for converting sunlight and carbon dioxide into glucose, which is used to provide energy to the plant. Leaves are classified into mainly two types based […]

Nucleic Acid Chemistry and Structure in Detail

DNA nucleic acid

Nucleic acids are molecules of high molecular weight formed by thousands of nucleotides. Nucleic acids are of two types- deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The primary function of the nucleic acids is to store and transmit genetic information from one generation to another. Nucleic acids can be digested by lysosomic enzymes. Nucleic Acid […]

DNA Replication |Step by Step Process and Enzymes involved

DNA replication

Reproduction is an important process for propagation of living organism.  To facilitate reproduction the genetic material in the cell of the organism needs to be multiplied so that the genetic characters can be passed off into the offspring. The genetic material of most organisms is usually DNA while RNA acts as a messenger. Structure The […]

Herbivores vs Carnivores | Important Differences in 15 Points

Herbivores vs Carnivores

Herbivores are the animals which rely on vegetation for food. While carnivores depend on other animals for their food needs. However there are many other variations. Herbivores vs Carnivores Sl.No Characteristics Herbivores Carnivores 1 Nomenclature The term ‘herbivores’ comes from the Latin word ‘herba’ means green plants. Herbivores are plant eaters The term carnivores come […]

Life Cycle of Frog | Metamorphosis from Tadpole to Adult

Life Cycle of Frog

The whole life cycle of a frog occurs in three stages: Egg Tadpole (larva) Adult frog The development of tadpole (juvenile state) into an adult frog is called metamorphosis. By this a of young larva of frog changes into an adult. To lay eggs, the female frog should mate in the breeding season to ensure […]

Chloroplast Structure and Function in detail with Labelled Diagram

Chloroplast Structure and Function

The leaves of the trees are colored in different shades of green. This color is imparted due to the presence of various pigments present in the cells of the leaves.  The 3 types of pigments present in plants are chlorophyll, carotenoids, and anthocyanins. Chlorophyll imparts the green color to plants. Plastids are membrane-bound cytoplasmic organelles […]

Types of plant cells | Their Examples and Functions

Types of plant cells

The cells of plants are broadly divided into two types. The permanent tissues generally don’t divide further. The types of plant cells are Parenchyma Collenchyma, and Sclerenchyma. However, these cells are arranged into tissues as Simple tissues Complex tissues Simple tissues Simple tissues making up the ground layers in plants. They are of three types […]
