 Why has C. elegans proven to be a useful model for understanding apoptosis?

#Part-B Specialized Branches in Biotechnology

  1. C. elegans does not naturally use apoptosis, but can be induced to do so in the laboratory.

  2. C. elegans undergoes a fixed and easy-to-visualize number of apoptotic events during its normal development.

  3. C. elegans has large cells wherein apoptosis is easily observed without the aid of a microscope.

  4. As C. elegans ages, its cells die progressively until the whole organism is dead.

Which of the following statement is true?
A) PAM matrices are derived from an evolutionary model whereas the BLOSUM matrices consist of entirely direct observations. 
B) Because of BLOSUM matrices have less evolutionary meaning that is why the PAM matrices are used most often for reconstructing phylogenetic trees.
C) BLOSUM matrices are entirely derived from local sequence alignments of conserved sequence blocks, whereas the PAM matrix is based on the global alignment of full-length sequences.
D) BLOSUM matrices are more advantageous in searching databases and finding conserved domains in proteins.
