Oligonucleotide-directed mutagenesis

The basic PCR mutagenesis system involves the use of two primary PCR reactions to produce two overlapping DNA fragments, both bearing the same mutation in the overlap region; this technique is thus termed overlap extension PCR .

In selective autophagy

specific cargo is packaged into autophagosomes that tend to contain little cytosol, mediates the degradation of worn out, or unwanted, mitochondria, peroxisomes, ribosomes, and ER; used to destroy invading microbes.

The stem cell lineage always undergoes meridional ,division to produce

(1) An anterior founder cell (AB)

(2) A posterior cell (P1) that will continue the stem cell lineage.
