Blog 3: Molecules

Molecules

     Molecules are special things in life. They can make up a lot of things. They are the smallest unit and they can be created by two or more atoms by a chemical bond. Molecules can be everywhere like plants, animals, non-moving objects, and even us. They help us do many things. So, basically molecules are everywhere but they are small.

Enzymes!!! 

Enzymes

Ligases

What are they?
     Ligases are responsible for the catalysis of ligation, joining of two substrates. A chemical potential energy is required,  so the reaction is together with the hydrolysis of a disphosphate bond in a triphosphate.

DNA Ligases

        The most important one is the DNA ligases. It catalysis the ligation between breaks in DNA by a bond. There are different forms of enzymes, and the catalyze different breaks. The DNA ligase can repairs single stranded breaks using complementary strand as a template.
