Answer: One of the primary differences between DNA and RNA is that DNA is double-stranded while RNA is single-stranded.
A non-disjunction in meiotic anaphase occurring in either an egg or sperm might produce a human zygote with 45 chromosomes. A condition in which human contain 45 chromosomes instead of 46 chromosomes is called aneuploidy or abnormal chromosome number.
<h3>What is aneuploidy?</h3>
The occurrence of one or more extra or missing chromosomes leading to an unbalanced chromosome complement, or any chromosome number that is not an exact multiple of the haploid number (23). It is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46. An extra or missing chromosome is a common cause of some genetic disorders. The most common cause of aneuploidy happens during cell division when the chromosomes do not separate properly between the two cells.
