Chemical damage to DNA can occasionally occur just before DNA replication begins. If the repair system does not have enough time to correct the error before the DNA is duplicated, this can give rise to mutations. In the sequence TGATT, if the adenosine is depurinated and not repaired, which of the following is the point mutation you would observe after this sequence of DNA has gone through two rounds of replication? a. TGATT
b. TGTTT
c. TGGTT
d. TGTT
e. TATT

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
