The gene that codes for any RNA/protein product which does not serve as regulatory protein is known as structural genes. The operator is a DNA sequence present between the promoter region and the first coding gene. The operator region serves as the repressor protein binding site. The promoter is a DNA segment that serves to initiate transcription of a particular gene. They are present upstream near the transcription start sites of genes in between the operator and structural gene. The regulatory gene regulates the expression of structural genes by its protein products that are mostly transcription factors. It is not the part of an operon, which means that it is present upstream or downstream the structural genes but not in between; the Regulatory gene is present upstream the operator gene. All living being having genes.Genes are a set of instructions that determine what the organism is like ,its appearance,how it survives,and how its behave in its environment. Genes are present in the nucleus in the chromatic material.......usually in the chromosomes

Dharshan M.R 2 years, 1 month ago

Soil microorganisms (figure 1) are responsible for most of the nutrient release from organic matter. When microorganisms decompose organic matter, they use the carbon and nutrients in the organic matter for their own growth. They release excess nutrients into the soil where they can be taken up by plants.

What enhances the water holding capacity of the soil.

Posted by Ayush Tiwari 2 years, 2 months ago

CBSE > Class 08 > Science

4 answers

Yoshiko Sasaki 2 years, 1 month ago

The addition of organic matter to the soil usually increases the water holding capacity of the soil. This is because the addition of organic matter increases the number of micropores and macropores in the soil either by “gluing” soil particles together or by creating favourable living conditions for soil organisms.
