Stem cell research has and can lead to medical cures.
Answer:
Blood vessels are found throughout the body. There are five main types of blood vessels: arteries, arterioles, capillaries, venules and veins. Arteries carry blood away from the heart to other organs.
Explanation:
The glycocalyx is present in the human vascular and digestive system. Endothelial cells lining blood vessels have a glycocalyx to protect them from the sheer stress of blood flow, as well as to aid in cell attachment that helps the immune system and blood clotting
Answer:
DNA polymerase
Explanation:
Prior to cell division, the DNA of that cell must be replicated in order for each daughter cell to receive the correct amount of genetic material (DNA). This process of DNA replication occurs in the Synthesis phase of Interphase. Before DNA starts replicating, the double-stranded DNA is unwound by an enzyme called DNA HELICASE to form two separate single strands.
Each of these strands serves as a template for replicating a new strand. An enzyme called DNA primase catalyzes the attachment of short nuceleotide sequences called PRIMER to the template strand in order for DNA POLYMERASE to synthesis/add new nucleotides to the growing DNA.
DNA polymerase adds nucleotides that are complementary to the ones it reads on the template strand.
