DNA Recombination – Definition, Mechanisms, Types

DNA Recombination - Definition, Mechanisms, Types

What is DNA Recombination? The main thing that happens in recombination is the exchange of genetic information. Types of DNA Recombination Recombination is mainly of four types: There are two other kinds of recombination that are used in recombinant DNA technology. It is well known that restriction endonucleases and DNA ligases can cut and join … Read more

Characteristic of Genetic Code

Characteristic of Genetic Code

Genetic code refers to the rules which the linear nucleotide sequence identifies what is the linear structure of the polypeptide. This means that they define what sequences of nucleotides in an mRNA transformed to the amino acid sequence in the polypeptide.

Ecological Succession – Definition, Types, Mechanism, Examples

Ecological Succession - Definition, Types, Mechanism, Examples

What is Ecological Succession? Ecological Succession Definition Ecological succession is the systematic and predictable process by which species composition in an ecosystem changes over time, progressing from initial colonization to a mature and stable community. Characteristics of Ecological Succession Ecological succession is a fundamental concept in the realm of ecology, delineating the sequential transformation of … Read more

Pyramid of Numbers – Definition, Types, Importance, Examples

Pyramid of Numbers - Definition, Types, Importance, Examples

What is Pyramid of Number? The Pyramid of Numbers is a graphical representation used in ecology to illustrate the distribution of various species in different trophic levels of a food chain. This pyramid provides a quantitative analysis, showing the number of individual organisms present at each trophic level. Unlike other ecological pyramids which might consider … Read more

Microbial interaction – Definition, Types, Characteristics, Examples

Microbial interaction - Definition, Types, Characteristics, Examples

Microbial interaction is a biological interaction in which the effect of microorganisms on other biotic components of an ecosystem can be investigated. Microbiology is the study of microorganisms, and microbial ecology is the study of microbial interactions within an ecosystem. Positive and negative microbial interactions are possible, and microbes can affect (positively or negatively) other … Read more

Carbon Fixation – Process, Pathways, Importance

Carbon Fixation - Process, Pathways, ImportanceCarbon Fixation - Process, Pathways, Importance

What is Carbon Fixation? Carbon Fixation Definition Carbon fixation is a biological process where atmospheric carbon dioxide (CO2) is converted into organic compounds, primarily by plants, algae, and certain bacteria. This process is a key component of photosynthesis, enabling the incorporation of inorganic carbon from the atmosphere into organic molecules like carbohydrates, thereby playing a … Read more

Primary Consumers – Definition, Importance, Examples

Primary Consumers - Definition, Importance, Examples

Primary consumers are fundamental components of ecological food chains, holding a critical position as the link between producers and higher trophic levels. In essence, they are organisms that feed directly on primary producers, typically plants or algae, which are capable of photosynthesis. Occupying the second trophic level, primary consumers are mostly herbivores, although some omnivorous … Read more

Secondary Consumers – Definition, Types, Functions, Examples

Secondary Consumers - Definition, Types, Functions, Examples

What are Secondary Consumers? Definition of Secondary Consumers Secondary consumers are organisms that primarily feed on primary consumers, which are herbivores, in a food chain. They occupy the third trophic level and can be either carnivores, who eat only other animals, or omnivores, who consume both animal and plant matter. Their role is vital in … Read more
