Lysosomes
They store waste in the cell until it is ready to be disposed
In humans fertilization occurs in the end of the fallopian tube away from the uterus (close to the ovary). The egg and the associated cumulus cells are ovulated (released) from an ovarian follicle and picked up by the fallopian tube. The tube pulls it inside where the sperm can find it.
The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
To ensure the continuity of the species
increase variation in species for natural selection to occur
Answer:
b. Elongation
Explanation:
During the start of the elongation phase of RNA synthesis, the sigma subunit of RNA polymerase of <em>E. coli</em> is released and NusA protein takes its place. This makes the RNA polymerase to move away from the promoter.
During the elongation phase of RNA synthesis, the enzyme DNA dependent RNA polymerase elongates the RNA strand by addition of ribonucleotides to the free 3'-OH end. The process occurs in 5' to 3' direction and the 3'-OH group serves as a nucleophile.
