For most activities it usually lasts at least 90 seconds in duration for you to solely rely with lactic acid. <span>The ultimate energy fuel is adenosine triphosphate (ATP), which is produced in the cell. Lactic acid in the cell will itself metabolize into ATP, a process by which energy can be produced without oxygen, known as the anaerobic lactic energy system. </span>
Answer:
B.) Replication fork
Explanation:
The replication fork is the point at which two strands of DNA separate via DNA helicase.
The origin of replication is the site on a singular DNA strand where replication begins. Here, complementary nucleotides begin bonding to the single-stranded DNA via DNA polymerase.
The replication bubble is created when DNA helicase separates a DNA strand. The DNA helicase does not separate the entire strand, but rather opens only certain sections at one time. This creates a "bubble" in the DNA strand where replication will take place.
Okazaki fragments are formed on the lagging strand of the single-stranded DNA. Because DNA is only created from the 5' to 3' direction, RNA primase must reposition itself after adding a primer (made of nucleotides). DNA polymerase then fills in these fragments with more complementary nucleotides in small sections.
