Any mutations in DNA are forever, since DNA is the master blueprint. All mutations will be passed onto new cells through DNA replication, and all RNA made from that DNA will also have the mutation. If the mutation occurs in sperm or egg cells, those mutations will also be passed on to the organism's offspring.

When an infant suckles at its mother's breast, milk moves through the breast structures in the order
Acinus - lactiferous duct - lactiferous sinus - nipple
When an infant suckles, milk is secreted from lactocytes into the alveoli (acinus). The milk is then squeezed from the alveoli so it can drain into the lactiferous ducts, milk drains from lactiferous ducts into lactiferous sinuses, and discharge through the nipple pores.
Hence, when an infant suckles at its mother's breast, milk moves through the breast structures in the order
Acinus - lactiferous duct - lactiferous sinus - nipple
