Before DNA polymerase can begin assembling DNA nucleotides to produce either the Okazaki fragments of the lagging strand or the continuous molecule of the leading strand, RNA primase must construct a short RNA primer.
The RNA primer serves as a starting point for DNA polymerase to begin adding nucleotides to synthesize a new DNA strand. DNA polymerase requires a 3'-OH group to add the first nucleotide, and since DNA strands can only be elongated in the 5' to 3' direction, a primer with a free 3'-OH group is needed.
Once the RNA primer is in place, DNA polymerase can add deoxyribonucleotides to the growing DNA strand, either continuously in the leading strand or in short Okazaki fragments in the lagging strand. After the DNA polymerase finishes adding the nucleotides, DNA ligase forms a phosphodiester bond between the 3' OH of the growing strand and the 5' phosphate in front of it, sealing the nick between the Okazaki fragments or completing the continuous strand.
While DNA polymerase-I does play a role in DNA replication, it is primarily involved in removing RNA primers and replacing them with DNA nucleotides, rather than in initiating DNA synthesis. Breaking hydrogen bonds between the two strands of DNA is also important for DNA replication, but it is not a necessary step before DNA polymerase can begin synthesis.

which molecule has both hydrophilic and hydrophobic properties and is found in plasma membranes? group of answer choices 6 1 3 5
The molecule that has both hydrophilic and hydrophobic properties and is found in plasma membranes is 5, phospholipids. Option 4 is correct.
Phospholipids are the main component of plasma membranes, which surround and protect the cell. They have a hydrophilic head and a hydrophobic tail, which makes them amphipathic. The hydrophilic head is composed of a phosphate group and a glycerol molecule, while the hydrophobic tail is composed of two fatty acid chains.
This unique structure allows phospholipids to form a bilayer in which the hydrophobic tails face inward and the hydrophilic heads face outward, creating a barrier that separates the inside and outside of the cell. This bilayer also regulates the movement of molecules in and out of the cell, which is critical for maintaining homeostasis. Hence Option 4 is correct.

Sarin gas is an irreversible inhibitor of acetylcholinesterase, an important enzyme in the nervous system that breaks down the neurotransmitter acetylcholine. Sarin gas forms a covalent bond with a serine residue in the active site of the enzyme, which permanently blocks the enzyme's activity.
As a nerve agent, sarin gas is highly toxic and can cause severe respiratory distress, seizures, and ultimately death if not treated promptly. Its mechanism of action involves overstimulation of the nervous system by inhibiting the breakdown of acetylcholine, which can lead to an accumulation of the neurotransmitter at the synapse and continuous stimulation of the postsynaptic neuron. Therefore, the irreversible inhibition of acetylcholinesterase by sarin gas is a key factor in its ability to disrupt the nervous system and cause serious harm to the body.

how is the structure of the trachea adapted to its function?
The trachea is a tube made up of rings of cartilage which is connected to the larynx and bronchi. The structure of the trachea is adapted to its function as it provides a passageway for air to travel to and from the lungs. The cartilage rings keep the trachea open and allow air to pass through freely.
The trachea is a cylindrical tube that extends from the base of the larynx to the bronchi. The trachea's shape is maintained by rings of cartilage, which are C-shaped cartilage rings with open ends facing the oesophagus. The cartilage rings give the trachea its form and prevent it from collapsing. The trachea's smooth muscle layer contracts and relaxes in response to autonomic nerve signals, altering the airway's diameter to control airflow. The trachea is lined with a mucous membrane, which produces mucus to trap foreign particles and prevent them from reaching the lungs.
Therefore, the structure of the trachea is well adapted to its function. The shape and strength provided by the cartilage rings prevent the trachea from collapsing when air is drawn in, while the smooth muscles in the tracheal wall can contract and relax to control airflow.The mucous membrane lining of the trachea secretes mucus, which helps to keep the airway clear and prevent the entry of foreign particles and microorganisms. Because of these adaptations, the trachea is able to provide a clear and unrestricted airway that is necessary for breathing.
