Which class of enzymes catalyzes reactions involving the formation of double bonds?

vodka [1.7K]

Lyases

Lyases are class of enzymes that catalyzes reactions involving the formation of double bonds.

Lyases are class of enzymes that catalyzes the joining of C-C ( carbon to carbon), C-O (carbon to oxygen), and C-N (carbon to nitrogen) bonds by hydrolysis or oxidation. These bonds are usually held by the process of elimination which leads to the formation of new double bonds or cyclical molecules. Examples of lyases include; aldolase and adenylate cyclase.

G you extracted your dna from cheek cells. the concentration of your dna sample is 250 ng/μl. the dna template for pcr should be

Karo-lina-s [1.5K]

You should mix 4µl of DNA sample and complete it with 96µl (100-4) of water.

You can figure this out by using C1.V1 = C2.V2
C1 = 250 <span>ng/μl (Sample Concentration)
</span>V1 = ? (the necessary volume to take from the DNA sample)
C2 = 10 <span>ng/μl (PCR concentration)
</span>V2 = 100 µl (total volume)

V1 = $\frac{C2 . V2}{C1}$ = $\frac{10 . 100}{250}$ = 4µl

For the water: 100µl (total volume) = 4µl + Water
Water volume = 96µl
