Proteins (Polypeptides with a unique amino acid sequence) are required to guarantee that the accuracy of replication is compatible with the low frequency of errors that is needed for cell reproduction Helicases unwind the two strands of parental DNA and creates the replication fork; single strands binding proteins keep the single strands from reuniting
Answer:
Fracture of the lower jaw following tooth extraction is a rare and severe complication, occurring most often in the preangular region following third molar extraction. When left untreated, pseudoarthrosis can occur.
The asthenoshere is a highly viscous, mechanically weak, ductile region of the upper mantle of Earth. Parts of it are made from rock melt.
The flowing asthenosphere carries the lithoshpere of the Earth, including the continents on its back.
The type of proteins that can function as the chemical messengers or as the receptors in the plasma membrane is a communication proteins; option A.
Proteins are large macromolecules composed of chains of amino acid units linked together by peptide bonds.
Proteins serve various functions such as:
communication
transport
defensive
enzyme
Communication of proteins such as the hormones can be function as the chemical messengers or as receptors in the plasma membrane.
Proteins are made up of hundreds or the thousands of the smaller units called as amino acids, which are attached to one another in the long chains. There are about 20 different types of amino acids that can be combined to make a protein.

Answer:
The human brain is the command center for the human nervous system. It receives signals from the body's sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains.The largest part of the human brain is the cerebrum, which is divided into two hemispheres, according to the Mayfield Clinic. Underneath lies the brainstem, and behind that sits the cerebellum. The outermost layer of the cerebrum is the cerebral cortex, which consists of four lobes: the frontal, parietal, temporal and occipital. [Nervous System: Facts, Functions & Diseases]
Like all vertebrate brains, the human brain develops from three sections known as the forebrain, midbrain and hindbrain. Each of these contains fluid-filled cavities called ventricles. The forebrain develops into the cerebrum and underlying structures; the midbrain becomes part of the brainstem; and the hindbrain gives rise to regions of the brainstem and the cerebellum.
