cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules.
Answer:
The last option is the correct order of events in mitosis.
Explanation:
The metaphase stage initiated with the arrangement of sister chromatids on the metaphase plate. Post arrangement, the spindle fibers come and combine with the chromatids kinetochore. The cohesion proteins assist in the robust attachment of the spindle fibers and the kinetochore. After the attachment is done, the pulling of sister chromatids takes place towards the pole. The dissociation of cohesion proteins takes place, and the nucleus begins to form again and thus, a novel cell gets formed.
Answer:
Mutation
Explanation:
A Mutation alters the genetic message carried by that gene as there are permanent changes in the nucleotide sequence of DNA or a DNA gene.
This can occur by base pairs substitution, deletion or insertion
