WebCardiac repair and regeneration. The heart is unable to regenerate heart muscle after a heart attack and lost cardiac muscle is replaced by scar tissue. Scar tissue does not contribute to cardiac contractile force and the remaining viable cardiac muscle is thus subject to a greater hemodynamic burden. Over time, the heart muscle eventually ... WebThe integrity of the DNA structure for cell viability is underscored by the vast amounts of cellular machinery dedicated to ensure its accurate replication, repair, and storage. Even still, mutations within the DNA are a fairly common event. Mutations are random changes that occur within the sequence of bases in DNA.
