The correct answer is adherens junctions.
Adherens junctions or zonula adherens are the cell–cell junctions in epithelial tissues. This type of junction is formed when cytoplasmic face is linked to the actin cytoskeleton and the proteins included in adherens junctions are cadherins and catenins. Adherens junctions can be:
• zonula adherens - appear as bands that encircle the cell or
• adhesion plaques – appear as spots of attachment to the extracellular matrix.
Telomerase is an enzyme that longs telomeres, which are fundamental repeats at the ends of chromosomes whose length is associated with cellular aging.
<h3>What are telomeres?</h3>
Telomeres are specific long tandem repeats located at the ends of all chromosomes in the cells.
These repeats (telomeres) are fundamental during cell growth and cellular aging.
It has been shown that telomerase can avoid the shortness of telomeres and thus can be used to slow cellular aging.
