Answer:
- A signal for apoptosis that comes from outside the cell is when a cell detaches from extracellular matrix. If this happens, a transmembrane signal is triggered.
- Two examples of cellular occurrences that would prompt an apoptosis signal from inside the cell are:
1. Damaged DNA
2. Increase of cytosolic calcium concentration
Explanation:
Apoptosis can be activated from an intrinsic or an extrinsic pathway. The intrinsic pathway is activated when a cell senses stress (for example, damaged DNA or high cytosolic calcium concentration) and triggers death proteins to activate apoptosis mechanism inside of it; the extrinsic pathway refers to the apoptosis triggered by signals that come from other cells. In this scenario, ligands bind to cell-surface death receptors and activates a death-inducing signal.
A reading frame consists of groups of 3 bases that each code for one amino acid<span>. A frameshift mutation shifts the grouping of these bases and changes the code for amino acids. The resulting protein is usually nonfunctional. Insertions, deletions, and duplications can all be frameshift mutations.

The cancer-causing genes that respond to the hdac inhibitors are likely to be Proto-oncogenes.
What is gene?
The term "gene" has a variety of meanings in biology. The molecular gene is a segment of nucleotides in DNA that's also translated to produce a functional RNA, whereas the Mendelian gene is the fundamental unit of heredity. Protein-coding genes as well as noncoding genes are the two categories of molecular genes. DNA will be first copied into RNA during gene expression. The RNA may perform a specific function directly or may serve as an intermediate template for just a protein. The basis for the inheritance of phenotypical is the transfer of genes to an organism's progeny.
