Explain how the interaction between mRNA codons and tRNA anticodons codes for a specific amino acid<span>
Answer: mRNA codons holds the info for specific amino acids. Anticodons are tRNA sequences complementary to the mRNA codons that bring the specific amino acids for the protein.</span>
T² = (4π²/GM)a³; where T is in Earth years, a is distance from sun in AU, M is the solar mass (1 for the sun), G is the gravitational constant.
In the given units, 4π²/G = 1
T² = 0.66³
T = 0.536 Earth years = 195.71 Earth days
