Contains one set of chromosomes?

Explanation:
Having one complete set of chromosomes means a cell carries a single copy of each chromosome type. This is the state of haploid cells, such as gametes produced after meiosis, which contain one chromosome from each homologous pair. In contrast, codons or triplets are three-nucleotide sequences within mRNA that encode amino acids; tRNA is the molecule that brings amino acids to the ribosome; mRNA is the RNA that carries the genetic code. None of those are about chromosome sets. So the term that fits “contains one set of chromosomes” is a haploid cell.
