The chart very nicely lays out the amino acid each codon corresponds to. You're looking for "trp" in the chart, which only appears once, beside the UGG codon. Therefore, only one codon codes for tryptophan.
A chemoorganotroph and a chemolithotroph in the same environment would not compete for - carbon
A chemoorganotroph is an organism that gets its energy from oxidation of reduced organic compounds. A chemolithotroph is someone who is able to use inorganic reduced compounds as a source of their energy. This process is accomplished through oxidation and ATP synthesis.
C. Lactic acid fermentation
Answer:
B. DR, Dr, Rd, dr
Explanation:
This question involves two genes. Alleles D and R are dominant over alleles d and r. These two genes obey the law of independent assortment as proposed by Gregor Mendel.
Based on the question, a genotype RrDd will produce the following combination of gametes following the process of meiosis:
DR, Dr, dR, dr
