Prophase- <span>chromosomes become visible as paired chromatids and the nuclear envelope disappears.
metaphase- </span><span>chromosomes become attached to the spindle fibers.
anaphase- </span><span>chromosomes move away from one another to opposite poles of the spindle.
telophase- </span><span>the final phase of cell division in which chromatids, or chromosomes, move to opposite ends of the cell and two nuclei are formed.</span>
They produce saliva which is essential for the breaking down of carbohydrates.
The Endoplasmic reticulum is the organelles that is involved in the synthesis of oils.
<u>Explanation:</u>
The endoplasmic reticulum is of 2 types that is the ''smooth endoplasmic reticulum'' and the ''rough endoplasmic reticulum''. The rough endoplasmic reticulum is lined with ribosomes whereas the smooth endoplasmic reticulum is plain.
Since ribosomes are present the rough endoplasmic reticulum is involved in protein synthesis whereas the smooth endoplasmic reticulum is involved in the production of oils or lipids that are required for the cell.
The answer is; DNA
The central dogma is DNA- RNA- Protein
Gene therapy involves the replacement of bad genes in the DNA of a human subject with a better gene. A recessive/mutated allele is removed and a healthy one is inserted. This way, the proper proteins can be produced solving the disease trait. Ultimately, it will not require drugs to treat the disease.
