The process of protein synthesis on ribosomes is called: MCQ with Answer and Explanation

Explanation:
Fertilization in humans typically occurs in the fallopian tube (ampullary region), not the uterus; the zygote then travels to the uterus for implantation. The placenta is the vital organ providing oxygen and nutrients to the growing fetus and removing waste. Spermatogenesis, the production of sperm, occurs in the seminiferous tubules of the testes. Thus, statements 2 and 3 are correct.

Explanation:
Ethylene is a gaseous plant hormone that is widely known for its role in promoting the ripening of fruits. It increases the respiration rate during fruit ripening (climacteric rise) and breaks down cell walls, converting starches to sugars, making the fruit softer and sweeter. It is also involved in leaf abscission and the triple response in seedlings.

Explanation:
Restriction endonucleases (restriction enzymes) recognize specific palindromic DNA sequences and cleave the phosphodiester bonds, producing sticky or blunt ends. They are essential tools for recombinant DNA technology. DNA polymerase synthesizes DNA, ligase joins fragments, helicase unwinds. Examples: EcoRI, HindIII. These enzymes are naturally present in bacteria as a defense against viruses.
