What is the primary purpose for the receptor proteins located within the cell

1 answer:

3 0

Receptor proteins are molecules inside a cell or on its surface on which ligands bind. A ligand is any substance (e.g. a hormone, drug, functional group) that binds specifically and reversibly to another chemical entity to form a large complex. Receptor proteins found inside a cell are called internal receptors or intracellular receptors or cytoplasmic receptors. They act as regulators of mRNA synthesis to mediate gene expression. When a ligand binds to an internal receptor, the receptor changes in conformation and exposes on itself a site that can bind to DNA. The receptor joined to the ligand moves into the nucleus where it binds to a specific site on the cell DNA. Once bound, it promotes the process of transcription where information is copied from DNA to mRNA

Pyroclastic flow would be most likely In a(n) ____Eruption

nlexa [21]

Answer:

The correct answer is Plinian eruption.

Explanation:

Pyroclastic flows are all secretions combined with robust materials and gases. The speed of pyroclastic flows on the number of solids and gases. A characteristic of pyroclastic flows is that they can produce a high degree of destruction when they erupt.

When talking about plinian eruptions, they refer to those characterized by volcanic ash in the stratosphere, and their gas eruptions are powerful.

olga2289 [7]

Answer:

Every amino acid in the chain changes, making the protein not functional

Explanation:

The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.
