Answer:
The Miller-Urey experiment was conducted to simulate the conditions on Earth when life arose, and see if a chemical evolution could occur. This experiment was performed without oxygen, because they knew that if oxygen was added, the amino acids would oxidize. In particular, the experiment intended to simulate a volcanic eruption was analyzed.
Thus, particles of water, methane, ammonia and hydrogen were exposed to high temperatures and electric discharges that simulated these eruptions, during a determined period. Later, it was observed that organic compounds had emerged from this exposure, which allowed us to infer one of the hypotheses regarding the origin of life on Earth.
Answer:
Segments of DNA transferred from parent to offspring are called genes
Explanation:
Just Cuz
Answer:
By using sequence information from covalently attached nucleotides.
Explanation:
TRNA presents an anticodon sequence to required sites as a physical bridge with elongation factors (proteins) to form a connection between mRNA and ribosome and encode amino acids to ultimately form specific protein structure. tRNA carries out this activity by using sequence information from covalently attached nucleotides.
