The role of 3tc in inhibiting hiv reproduction is to interfere with enzyme trancriptase since it has a similar shape to the c nucleotide of DNA.Reverse trancriptase pick up 3tc molecule which led to termination of DNa further thus block reproduction of HIV.
Humans caused damaged by all the pollution in the earth atmosphere with is making global warming it changes by how much pullution is going into the atmosphere
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.
