Answer is thousands of different proteins
Proteins are macro-molecules, made up of small units or building blocks. These building blocks are called amino acids. To build a protein, first the amino acids are connected into long chains, called polypeptide chains. These chains of amino acids fold into all types of shapes. Some chains fold into spirals. Combining these spirals, sheets, and loops is how the three-dimensional shape to build a functional protein. The human body uses just 20 amino acids to make all the proteins it needs to function and grow. Because amino acids can be arranged in many different combinations, it's possible for our body to make thousands of different kinds of proteins from just the same 20 amino acids.
According Jean Piaget, the belief that inanimate
objects possess emotions which in this case, the girl’s teddy bear, is called animism or
animistic thinking. It usually occurs during the pre-operational stage of
cognitive development. Children in this stage engage in symbolic plays and the
age range is usually from 2 to 7.
Answer:
Receptor tyrosine kinases undergo autophosphorylation.
Explanation:
The receptor tyrosine kinases (RTKs) are proteins that undergo dimerization and autophosphorylation after binding with their corresponding ligands, thereby triggering downstream molecular signaling cascades. The RTKs bind with high specificity to ligands including growth factors, hormones and cytokines. In human cells, there are 58 types of RTKs proteins that function to regulate developmental pathways, and their dysfunctions have been associated with cancer progression.
