Sulphur Cycle & Microbial Role in It

The sulfur cycle is the collection of processes by which sulfur moves between rocks, waterways and living systems. Such biogeochemical cycles are important in geology because they affect many minerals. Biochemical cycles are also important for life because sulfur is an essential element, being a constituent of many proteins and cofactors, and sulfur compounds can be used as oxidants or reductants in …

Synecology: Definition, Subdivision & Scope

Definition of ecology The word ecology originated from two Greek words; Oikos meaning ‘household’, ‘home’, or ‘place to live’ and ‘logos’ meaning knowledge. Therefore, ecology deals with the organism and its place to live. The word ‘ecology’ was first used in the 2nd half of the 19th century by Henry …

Interactions among Microbial Populations

Organisms living together in a community influence each other directly or indirectly under natural condition. All vital process of living such as growth, nutrition, reproduction required interactions between individuals of same species, or between species which are inter- and intra-related. Such relationships of individuals in a population of an ecosystem …

Translation: mRNA to Protein

Translation takes place on ribosomes; indeed, ribosomes can be thought of as moving protein-synthesizing machines. A ribosome attaches near the 5′ end of an mRNA strand and moves toward the 3′ end, translating the codons as it goes. Synthesis begins at the amino end of the protein, and the protein …

Genetic Code

The four bases in DNA – A, T, G, and C are sufficient to specify the 20 amino acids in proteins because each codon is three bases in length. Each sequence of three adjacent bases in mRNA is a codon that specifies a particular amino acid (or chain termination). The …

Chloroplast Evolution: Endosymbiotic Theory

Algae is a hetergenous group of organisms containing members having chlorphyll ‘a’ as their primary photosynthetic pigments. These green chlorophyll molecules along with some accessory pigments are contained generally in a membrane bound packet like structure called chloroplast within the algal body. In some members, chloroplast is absent though; such …

Origin Of Bryophytes

Though almost in all cases, when we talk about origin, it goes about the discussion of fossil, bryophytes don’t have any primitive form than what at present-day it is. Usually the study about the origin of bryophyte is something like hypothesis- based upon the comparative studies about the morphology, habitat …
