Q15.100 P - Chemistry: Molecular Nature Of Matter And Change

Question

Write the base sequence of the DNA template from which this RNA sequence was derived: UGUUACGGA. How many amino acids are coded for in this sequence?

Step-by-Step Solution

Answer

3'- ACA ATG CCT - 5' is the base sequence of the DNA template.

The sequence may be encoded using three amino acids.

Step 1: Base sequence of the DNA template

The base complementarily rule, which couples A with U and G with C, is followed by RNA, which is the transcript of the DNA template. Whether indicated or not, DNA templates and RNA sequences are always read in the 5' (5 prime) to 3' (3 prime) orientation. As a result, the supplied RNA base sequence will be written as follows:

5'- UGU UAC GGA - 3' RNA base sequence.

3'- ACA ATG CCT - 5' Base sequence of DNA template.

Step 2: How many amino acids are coded

The triplet nucleotide code is used to code each amino acid. There are nine nucleotides in all. As a result, the above sequence may be encoded using $\frac{9}{3}=3$ amino acids.
