Question

In an experiment to decipher the genetic code, a poly-AC mRNA (ACACACAC...) is synthesized.

What pattern of amino acids would appear if this sequence were to be translated by a mechanism that reads the genetic code as:

A triplet without overlaps?

Two different polypeptides would be produced, each one composed of a single type of amino acid.
The resulting polypeptide would be composed of two alternating types of amino acids.
The resulting polypeptide would be composed of a single type of amino acid.
Two different polypeptides would be produced, each one composed of two alternating types of amino acids.

Answer 1

Check the explanation

Step-by-step explanation:

Triplet with overlaps:

The outcome polypeptide would be composed of 2 alternating types of amino acids.

quadruplet without overlaps?

2 different polypeptides would be produced, each one composed of a single type of amino acid.

quadruplet with overlaps?

The outcome polypeptide would be composed of two alternating types of amino acids.

Note:

Triplet with overlap:

What this means is that the likely codon are : ACA & CAC. On translation this will result to a polypeptide with alternating amino acid.

Quadruplet without overlap:

This will yield two different types:

One will be ACAC repeat

Second will be CACA repeat.

So far the quadruplet is with overlap, ACAC & CACA will be the codons and we will get alternating amino acid in the resulting polypeptide.
