Codon charts are generally written as a messenger

Codon charts are generally written as a messenger RNA.

Explanation:

A genetic code can be described as a code made up of triplet nucleotides which is used to determine the sequence of amino acids being formed from a particular gene sequence. There can be more than one genetic codon for a sinlge amino acid.

For example, the genetic code for the amino acid asparagine (Asn) is  AAT and AAC.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

it is called the mitotic spindle
