Answer:

Regulatory gene

Explanation:

Transcription is one of the major processes that occurs during gene expression. It is the transfer of the genetic instructions in DNA to mRNA. A strand of mRNA is made using complementary base pairs.

However, there is need for gene expression to be regulated.

Gene regulation refers to the mechanism that acts to induce or repress the expression of a gene. These include structural & chemical changes to the genetic material, binding of proteins to specific DNA elements to regulate transcription. These proteins that influences transcription by binding to specific nucleotide sequences (DNA segments/gene) are referred to as REGULATORY PROTEINS and those involved in regulating transcription of genes are called TRANSCRIPTION FACTORS.

Regulatory proteins controls the rate and manner of gene expression by binding to specific genes, thus, making it easy or hard for RNA polymerase (enzyme that attaches to DNA to synthesize mRNA molecule) to bind to the promoter of that gene.

Transcription factors (regulatory proteins) that promote gene transcription are called ACTIVATORS while those that decrease are called REPRESSORS.

1. How does our ecological footprint affect each of the spheres on Earth?
Viefleur [7K]
Lithosphere (or geosphere) describes all the rocks, minerals and molten magma found on or in the Earth

The hydrosphere describes all the water on Earth – including liquid water (oceans, etc.) and vapour (precipitation)

The atmosphere describes the layer of gases surrounding the Earth and is divided into sections (stratosphere, etc.)

The biosphere is composed of all the living organisms on the planet (including plants, animals, bacteria, etc.)


The four spheres are interconnected, so human impact on one sphere will potentially effect other spheres

The release of plastic pollution into the oceans (hydrosphere) will impact on marine life (biosphere)

The production and release of CFCs into the atmosphere will effect the impact of UV radiation on the biosphere
