Answer:

To allow transcription enzymes to access the DNA strand

Explanation:

The DNA double helix is made up of two complementary strands wound around each other, and tightly packaged as chromosomes.

DNA and RNA polymerases promote either DNA or RNA synthesis by attaching free nucleases to parent strands (a), which are then unwound and isolated by helicases (b). DNApolys synthesize DNA in a 5'-3 ' direction; owing to its restricted flow, there are only two types of replication: continuous from the point of differentiation of chromosomes, fork, and discontinuous from the fork.

It’s quite interesting because
they give out lots of useful information.
But really this only scratches the surface on what they can do!

because a monoglyceride molecule has more carbon atoms than a glucose molecule, you can assume that...
Alexxandr [17]

The monoglyceride molecule contain more energy than a glucose molecule because monoglyceride requires more oxygen for each carbon atom because there are more electrons surrounding each carbon in monoglyceride. Therefore, to oxidize monoglyceride more oxygen having high affinity for electrons, are required. Thus, monoglyceride produces more energy.
