New types of bacteria being created!
Answer:
<h2>EGFR will activate other proteins without dimerization, causing uncontrolled cell growth.</h2>
Explanation:
EGFR gene
:
Epidermal growth factor receptor,
-which spans the cell membrane so that one end of the protein remains inside the cell and the other end located outer surface of the cell. This causes receptor to attach ligands, and to receive signals ,by which cell respond to its environment. Epidermal growth factor receptor binds to many different type of receptors. The binding of a ligand to receptor allows the receptor to attach to another nearby epidermal growth factor receptor protein (dimerize), activating the receptor complex. As a result, signaling pathways within the cell are triggered that promote cell growth and division and cell survival. If there is abnormlty in the expression of EGFR gene , then the cell show uncontrolled growth.
The genetic base of the shape of orchid is very complex.
Mendelian traits are described as simple traits determined by one gene. The different alleles of the gene contribute to the difference in the trait. This is true for some traits in plants, animals including humans and other organisms, but not for the shape of orchids.
The shape of orchid flowers is determined by the ABCDE group of genes that are responsible for the body plan in plants. These genes are the equivalent of HOX genes of animals.
The protein products of different genes of the ABCDE group interact with each other in complex ways creating different shapes of orchids.
