The _____ is a type of regulator protein that binds to a region of dna in the promoter of a gene called the operator and prevent
vivado [14]

The<u> repressor </u>is a type of regulator protein that binds to a region of DNA in the promoter of a gene called the operator and prevents transcription from taking place.

In the field of science, a regulator protein can be described as a kind of protein that affects the transcription of a gene by having an influence on particular DNA sites. The rate of synthesis of various proteins is controlled by the regulator proteins.

A repressor is a kind of regulator protein that prevents the transcription of a particular gene. When the rate of a protein in the body has reached normal, the transcription of the protein needs to be stopped in order for more protein of that kind to be formed. The repressor binds itself to the operator region for the gene, hence stopping the transcription process until the protein is required again.

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

Telomerase activity may decline with old age and this could explain why cells lose their ability to divide after many replicatio
Bumek [7]

It is true that telomerase activity declines with old age which explains why cells lose their ability to divide after many replications.

Telomeres are DNA–protein complexes found at the ends of each chromosome they contain repetitive sequences of DNA. Telomeres protect the genome from nucleic bases degradation, unnecessary recombination, repair, and prevent the fusion of chromosomes. Telomeres, therefore, play a vital role in preserving the information in our genome.

Telomeres shorten with every consecutive DNA replication cycle limiting the number of cell divisions a cell can undergo, Telomeres act as a tumor suppressor by halting the replication of cells which contains several mutations after many division cycles.
