<h3>What is DNA and what is its function?</h3>
DNA is the structure responsible for transmitting all genetic characteristics — such as eye, skin and hair color, physiognomy, among others — in the process of reproduction of living beings. In this way, the main function of DNA is to carry information contained in its sequences, called genes.
DNA is made up of two chains of polynucleotides (strand), which are made up of several nucleotides. Nucleotides are joined together by bonds called phosphodiester (phosphate group linking two sugars of two nucleotides).

Answer:
the Y chromosome is smaller than the X chromosome.
Explanation:

Males are heterogametic as they produce two types of gametes, one carrying the X and the other carrying a Y chromosome.
