To stop a wound from bleeding, platelets in the blood clump together to form a blood clot. The clot dries into a hard scab to pr
otect the wounded area. Underneath the scab, the blood supplies nutrients and oxygen that help new skin cells form. As the skin regenerates, the wound closes. Which body systems interact with the integumentary system to close the wound?
Compare and contrast a frameshift mutation and a single nucleotide substitution mutation in a DNA sequence encoding a protein. How many nucleotides would be inserted or deleted in each? How many amino acids in the protein sequence would be altered in each?
