Question

A DNA strand has the codon AAT. According to the chart, the corresponding messenger RNA codes for which amino acid?

Answer 1

Because Thymine is "replaced" with Uracil, the corresponding RNA Code for AAT would be UUA.

Answer 2

Answer:

Asparagine (symbol Asn)

Explanation:

In a gene, groups of three nucleotides (such as AAT) form codons that are read during translation, for the  synthesis of proteins.  The way codons are read can be found in a genetic code (attached here).

Before that, the DNA seuqences are transcripted to RNA sequences in order to be read and translated in the ribosome.

AAT (DNA sequence) will be transformed to  AAU during the transcription of DNA.  This is because during the transciption process all thymines (T) are replaced by Uracils (U).

In the genetic  code you can see that AAU is read as Asparagine.
