Answer:
c. Tubulin
Explanation:
Tubulin protein is polymerized to form the cylindrical structures of microtubules. Microtubules form the spindle apparatus during cell division. The spindle microtubules become attached to the kinetochores of chromosomes and mediate the alignment of chromosomes at the equator of cells during metaphase. The shortening of spindle microtubules is responsible for the movement of sister chromatids during anaphase. The same event also moves the homologous chromosomes during anaphase-I.
Any failure in the formation of the spindle apparatus would not allow the proper separation of chromosomes. Therefore, the cell with abnormal chromosome separation might have a faulty or no tubulin.
DNA has sequences that mRNA finds the pair for (ex. DNA says AGC, RNA says UCG)
with that, they only come in 3 nucleotide increments.
B is the correct answer because all the classes are hierarchy’s in a sense
Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy
