Two types of plant peroxisomes:

Present in leaves - participates in photorespiration.

Present in germinating seeds (glyoxysomes) - converts fatty acids into sugars.

Unlike base excision repair, the nucleotide excision repair enzymes do not recognize any particular lesion. Rather, this system works by recognizing distortions to the shape of the double helix, such as those

caused by a thymine dimer or by the presence of a bulky chemical adduct on a base.

Photopolymerization is an alternative method that can be used to polymerize acrylamide gels. Ammonium persulfate and TEMED are replaced by riboflavin and when the gel is poured it is placed in front of a bright light for 2–3 h.
