ANSWER: CANCER DEVELOPMENT
EXPLANATION:
Tumor suppressor genes (TSGs) are genes that regulates the cell cycle of a cell (i.e the cell division and replication). In other words, TSGs encodes protein that act as control or regulator of cell growth.
However, when there is an alteration in the genetic sequence (mutation) of the TSGs, this make the cell not to respond to cues that had been regulating it growth.
Thus, when cell growth is not regulated, it results to runaway or abnormal cell growth (i.e multiple folds cell division and replication), in other word referred to as “cancer”.
The correct answer is p53 gene.
This is one of the most important genes in our bodies, which is evident by its nickname of the "guardian angel of the genome." It is called that way because it protects our cells from becoming cancerous. It also activates many other genes.
When focusing a specimen you should always start with the SCANNING objective. Scanning objective is used to put the object you want to examine in focus. After proper focusing on the object, you can now switch to power objective.
