The drug colchicine inhibits the formation of spindle fibers during mitosis. If you treat dividing plant cells with colchicine,
vekshin1

Answer:

D

Explanation:

During metaphase of cell division, the chromosomes line up in the metaphase plate and the spindle fibers from the poles extend and attach to the centromeres of the chromosomes. The spindle then contracts and pull different chromosomes to the opposite poles of the cell before the parent cell divides.   If spindle fibers do not form, then the chromosomes will not separate during anaphase.

Therefore, the final cell after mitosis will be a cell with double the number of chromosomes -because if you remember, during interphase, genetic material is replicated so each daughter cell can have its copy-. Due to quality control in the process of cell divisison, this cell will mostly undergo apoptosis, otherwise, it could develop into cancer.

Biotechnology is best defined as what?
Lubov Fominskaja [6]
My answer -

<span> Biology is the study of living organisms. Biotechnology involves creating solutions to problems using living organisms. It's more like how mechanical engineering uses machines to solve problems or how computer engineering uses computers to solve problems.

The problems that biotechnology works to solve can range from medical treatments (like stem cells) to advancements in agriculture (disease or drought resistant plants, food with higher nutritional value) to industrial processes (bacteria developed to replace toxic compounds used to make paper, bacteria and algae that produce biofuels).

P.S

Happy to help have an AWESOME!!!! day :)
