Answer:
Codon: 3'-CGC-5'
Codon: 3'-UGC-5'
Explanation:
The anticodons of tRNAs bind to the complementary codons of mRNA. The mRNA codons are always read in 5' to 3' direction. The 5' base of an mRNA codon pairs with 3' base of the anticodon of tRNAs. The first base of the anticodon (the 5' base) determines the number of mRNA codons that are recognized by the tRNA. When the 5' base of the tRNA anticodon is U or G, it binding with codon is less specific. A tRNA anticodon with 5’ G base can read two different codons.
Anticodon: 5'–GCG–3'.
Codon: 3'-CGC-5'
Codon: 3'-UGC-5'
Answer:
I might be wrong but im guessing 600
Explanation:
Since there is one molecule of glucose used per 6 molecules of carbon dioxide released, if you have 100 molecules of glucose, then you multiply the carbon dioxide by 100 which is 600. Thats what I would say but I might be wrong.
Answer:
The answer is B. Some organic molecules, including amino acids, could have been produced from chemical reactions on early Earth.
Explanation:
Miller-Urey Experiment:
The Miller-Urey experiment was an attempt to explain the origin of life on Earth. Miller-Urey simulated the primordial soup i.e. the environment of primitive Earth to prove the spontaneous generation of organic molecules. The conditions they introduced included:
- A methane-ammonia-hydrogen and water mixture that exactly simulated the primordial soup.
- A spark of 70,000 volts that simulated lightening.
- A temperature of 800 degree Celsius.
Observations:
- After running for 18 days, the final solution was examined for presence of organic molecules.
- Miller-Urey observed that most of the methane and ammonia had been consumed and the mixture contained carbon monoxide and nitrogen.
- The solution further contained 25 amino acids (mainly, glycine, alanine and aspartic acid)
, several fatty acids
, hydroxy acids and amide products.
The experiment concluded that simple organic compounds such as amino acids could have been formed through spontaneous generation under the Earth's primitive environmental conditions.
