While looking at a cell under a microscope, a scientist is able to see a biological molecule. this molecule is a nucleic acid with double strands and contains the nitrogenous bases adenine, thymine, cytosine, and guanine. based on this information, what conclusion can the scientist draw regarding this nucleic acid?

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.
