All living organisms are composed of cells<span>. They may be unicellular or multicellular. The </span>cell<span> is the basic unit of life.</span>
Individual
members of the same species are genetically very different because of a process
called meiosis which creates gametes.
<span>During
the meiosis (prophase I) the process called crossing over occurs. Crossing-over
represents the exchange of genetic material between non-sister chromatids of
homologous chromosomes which results in new combinations of genes on each
chromosome (genetic variation).</span>
Answer: Option C) A gene unwinds and becomes a template that organizes amino acids.
Explanation:
A gene is a sequence of DNA nucleotides on a chromosome that codes for a polypeptide or RNA molecule and thus determine an individual inherited traits.
Therefore, the role of a gene production in organism traits is serving as template for directing different amino acid combinations, that generate different proteins, and in turn different traits.
