Answer:
The correct answer is a. Helicase unwinds DNA
Explanation:
DNA replication is a process in which DNA make it's own copy. There are several enzymes and factors which access the DNA replication process like helicase, primase, SSB protein, DNA polymerase etc.
The first step in DNA replication is the unwinding of double stranded DNA which is accomplished by an enzyme called Helicase. Helicase opens up the double stranded DNA at replication fork by breaking the hydrogen bond between the nucleotides of complementary strands.
This provides a single stranded template for DNA polymerase to form a new complementary strand. In <em>E. coli </em>Dna B is the primary helicase and in humans the primary helicase is MCM( minichromosome maintenance protein complex).
The body requires fuel and energy to perform the typical brain functions, physical activities, and operating of the organs. Carbohydrates provide the fuel and energy.
Lipids play a number of roles but one main role is the storage of energy. A lot like Carbohydrates they are incredibly important to our bodies. In that, they store and give us energy throughout the day.
I hope this helps!
