Is this a True or False Question?
No, dna is the “recipe” for who you are! If every organism had the exact same DNA everyone would look and be the exact same!
Answer:
Actively forms a peptide bond by acting as a ribozyme aid in initiation of protein synthesis.
Explanation:
The role of the 23S rRNA of the large ribosomal subunit of E. coli during protein synthesis is the formation of a peptide bond by acting as a ribozyme aid in initiation of protein synthesis. 23S rRNA has an important function of peptidyl transferase. Both peptidyl-tRNA and aminoacyl-tRNA are necessary for synthesis of protein and transpeptidation response. The 23S rRNA positions have a significant function in the binding of tRNA in P site of the large ribosomal subunit.
The Earth's tilt on it's axis
Answer:
Option B, It was made in stars that lived before the solar system formed.
Explanation:
Almost all the carbon that exists today with in the living organisms was produced in the stars. When these stars exploded during the big bang theory all the carbon within hem was introduced in the environment of earth some billions of years ago. Hence , though carbon introduced in earth’s environment was due to big bang, its origin is from the stars. Hence option B is the correct answer
Cyanobacteria is responsible for generation of oxygen on planet earth and thus option D is in correct.
