determine the bases that will code for the amino acid methionine.

Question

put the following in first, third, or second base.
uracil cytosine adenine guanine

Answer 1

Methionine is coded by the mRNA codon "AUG." In this codon, the bases play specific roles in their position:

• First base: Adenine (A)
• Second base: Uracil (U)
• Third base: Guanine (G)

So, specifically:

• First base: Adenine (A)
• Second base: Uracil (U)
• Third base: Guanine (G)

If you require the coding for methionine using uracil, cytosine, adenine, and guanine in the specific context of codons:

The codon "AUG" codes for methionine, where:

• A (first base) - Adenine
• U (second base) - Uracil
• G (third base) - Guanine

Thus:

• First base: A (Adenine)
• Second base: U (Uracil)
• Third base: G (Guanine)

Cytosine is not a part of the codon for methionine.
