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.

Check the explanation

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.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
