Answer:
None of the above.
Explanation:
GTPases are the regulatory proteins that are involved in the signal transduction pathway involving the activation of the G protein. The mutation in these proteins cal lead to cancer cells.
The guanine nucleotide exchange factors (GEF) allows the replacement of GDP by GTP. They activates the GTPase activity of the cell and can also activate the multiple GTPase activity of the cell. The Ras superfamily is activated by the GEF.
Thus, the correct answer is option (d).
A protein's shape directly affects how well it works. For instance, a protein works as a protective protein or a structural protein if its structure is fibrous, as is the case with proteins like collagen and keratin. The protein becomes denatured and ceases to serve its intended purpose if the structure of the amino acids is altered in any way.
<h3>What are amino acids?</h3>
Organic substances known as amino acids have both functional groups for amino and carboxylic acids. Alpha-amino acids, which make up proteins, are by far the most significant amino acids in nature, despite the fact that there are hundreds of other types. The genetic coding only contains 22 alpha amino acids. An organic compound is an amino acid. Carbon-hydrogen bonds are present in organic compounds. All amino acids share a similar fundamental structure. Each molecule has a core carbon atom that is joined to a hydrogen atom, a basic amino group, a carboxylic acid group, and an R-group, also known as a side-chain group.

Explanation:
Terrestial Animals - Animals which can only live on Land.Examples:- BEAR- CAT- DOG- DEER
Aquatic Animals - Animals which can only live on Water.
Examples:- FISH- OCTOPUSES- LOBSTERS- SEAHORSE
Amphibians - Animals which can live both on land and on water.
Examples:- FROGS- TOADS- SALAMANDERS
Arboreal Animals - Animals which live primarily on trees.Examples:- SQUIRREL- RODENTS- CHAMELEON
Both plant and animal development is seeded in the perspective that a cell divides itself to form a tissue and tissues grouped will become an organ and the organism itself. The cell hierarchial model is followed in the development in both of these diverse however seemingly similar organisms.
