Answer #1

Lck phosphorylated tyrosine residues within the cytoplasmic tail of the t cell receptor to activate native T cells.

Answer: True
Explanation:
Lck belongs to Src family of protein tyrosine kinases (PTKs). T cells originate in the bone marrow and its maturation takes place in
thymus where it differentiated to form memory T cells. Lck in T cells serves as a signalling
molecule by phosphorylating the tyrosine residue of T cell receptor in activation of T cells.
