PD1 is a programmed cell death protein 1. It is present on the surface of the T cells which is a type of immune cells. The main function of this protein is to regulate the immune response of our body. The T cells and B cells are among the main cells of the immune system . They can distinguish between the self and foreign particles or antigens. So they attack accordingly . But sometimes this cells get overactivated and start attacking the self cells or tissues. So this protein PD1 suppress these cells or check these cells from attacking the self tissues .

CAR -T are the Chimeric antigen T cells which are the genetically engineered T cells . These T cells are modified in such it is used in immunotherapy to treat cancer. It has an ability to target a specific protein.

Write a function to create a copy of a string with the prototype below. (C Language) char * strcpy (const char *); The function should dynamically allocate the necessary memory for the new string. You can do that with char * newstr = (char *) malloc(sizeof(char) * (strlen(str)+1)); assuming str is your input string. Think though how you would copy the characters of the string, and don't forget about the end of string character.
