Primarily, it detects peptidoglycan, which is present in a thick layer in Gram-positive bacteria. ... In Gram-positive bacteria, the cell wall is thick (15-80 nanometers), and consists of several layers of peptidoglycan. They lack the outer membrane envelope found in Gram-negative bacteria.

Antibodies have three main functions: 1) Antibodies are secreted into the blood and mucosa, where they bind to and inactivate foreign substances such as pathogens and toxins (neutralization). 2) Antibodies activate the complement system to destroy bacterial cells by lysis (punching holes in the cell wall).
Explanation:G 1 checkpoint is the main decision point of the progression of the cell cycle. It is the rate-limiting step of the cell cycle known as the restriction point. The G1 checkpoint occurs at the transition stage of the G 1 stage-cell into the S stage. Protein synthesis and DNA replication occur during the G 1 phase.
