Ligation reactions occur most efficiently between DNA fragments:

Biology
1 answer:
Ket [755]3 years ago
8 0

Answer:

<h2>B. that have complementary sticky ends</h2>

Explanation:

The sealing of nicks between two adjacent residues of a single-strand(ss) break on a double-strand DNA and the joining of double-strand breaks.

This is enzymatically catalyzed by the enzyme DNA ligase.

DNA ligation is the joining ends of 2 DNA molecules by the enzyme, DNA ligase. DNA ligase catalyzes the formation of two covalent phosphodiester bonds between the 3' hydroxyl group of one nucleotides and the 5' phosphate group of another and it is  an ATP dependent reaction.

DNA Ligation  occur most efficiently between those  DNA fragments  that have complementary sticky ends.

Dude why is bio so hard please help lol
Evgesh-ka [11]

Answer:

1.Sugar bonds

2.Transport proteins

3. Digestion

4. Oxidation

explanation

Chemical energy is stored in the bonds of sugar.

The concentration gradient of a substance across the membrane represents potential energy bcz it drives diffusion.Transport proteins aids the diffusion.

Digestion converts chemical energy into kinetic energy used by cells.

When the electrons are destroyed in the glucose,Energy contained in the bonds is released in small bursts,some of it is captured in the form of ATP .'The electrons are transferred to smaller molecules known as electron carriers.The electron carriers take the electrons to a group of proteins in the inner membrane of the mitochondrion,called the electron transport chain.As electrons move through the electron transport chain they go from a higher to lower energy level and are finally passed to Oxygen to form water.The energy released is captured as a proton gradient which powers the production of ATP.

Not 100% sure whether it's the correct answer but the concept is true 100% btw I stand to be corrected
