The endocrine system is responsible for maintaining homeostasis of the body via rapid transmission of electrical signals. This system is the group of glands that are responsible of producing hormones that functions to regulate growth and development, metabolism, tissue function, sleep, reproduction and other processes in the body. The glands are being controlled by stimulation of the nervous system and by the chemical receptors that are in the blood. It consists of the thyroid gland, parathyroid gland, pituitary gland, adrenal gland, ovaries for females and testicles for males and the pancreas. This system affect almost all of the organs and cells in the body.
Answer:
2 is correct if I'm not mistaken
Answer:
DNA Helicase
Explanation:
The process of DNA replication is very complex and requires a variety of proteins in the form of Enzymes.
The DNA replication starts at the site which is about 245 base pairs long and is rich in AT sequences called Origin of replication. The origin of replication recognised by an enzyme called DNA helicase which breaks the hydrogen bonds present between the bases and unwinds the DNA. The RNA primase enzymes then synthesizes an RNA primer which gets attached and to which DNA polymerase binds and add nucleotides.
Thus, the first enzyme that binds to the DNA is DNA helicase.
