To explain:
The functions of the accessory organs associated with the skin.
Introduction:
The accessory organs associated with the skin include nails, hair follicles, sebaceous glands and sweat glands. Nails are made up of the protein keratin which protect the underneath layer of the epithelial cells from injury. The hair follicles are present on the base of the hair with root shaft. The growth of the hair along with the melanocytes takes place from this region inside the dermis. Sebaceous glands are oily glands present on the skin. They secrete lipid substance called as sebum which nourishes and lubricates the skin cells. Sweat glands or sudorific glands secrete salt ions which maintain the temperature of the body. The sweat absorbs heat and maintains the temperature balance inside the body.

- Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forwardMolecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell.
