Q. 1 - Biology

Question

Figure 10.13 Rb and other proteins that negatively regulate the cell cycle are sometimes called tumor suppressors. Why do you think the name tumor suppressor might be appropriate for these proteins?

Step-by-Step Solution

Answer

Rb and other negative regulatory proteins inhibit cell divisions.

Step 1. Introduction

Tumor suppressor gene code for negative cell cycle regulator. The tumor suppressor gene prevents cancer in normal cells by decreasing or blocking cell growth.

 

Step 2. Explanation

Rb and other negatively regulatory proteins inhibit cell division and therefore prevent the formation of tumors so they are known as tumor suppressors. Mutations prevent them from carrying out their functions and can result in cancers.
