<em><u>Globin is the protein part of hemoglobin.
</u></em>
<u>The alpha globin family </u><u>is located on chromosome 16.</u>
<u>The beta globin family</u> <em><u>is located on chromosome 11.</u></em>
<em><u>The answer is</u></em>: <u>d.) On different chromosomes.
</u>
-------------
<u>The vast majority of genes encoding a protein encoded</u> <em><u>within the nucleus of metazoan cells</u></em> <u>contain both introns and exons.
</u>
<em><u>The answer is</u></em>: <u>b.) both exons and introns.
</u>
-----------------
<u><em>In the DNA sequence the coding content of a gene is not continuously distributed along said gene</em></u>, <u>but has discontinuities, called introns, whose sequence does not encode proteins</u>.
<em><u>The answer is</u></em>: <u>a.) Intron.
