Hypothesize why DNA replication has such accuracy

Biology

DNA replication has such accuracy varies. There are many DNA polymerases/repair enzymes that synthesize/repair DNA. Some are more frequent than others. The error frequency ranges between 1 to per 10,000 base pairs to 1 to per 10,000,000 base pairs, depends on the enzyme

Dangling high above the ground, this rock climber relies on muscular strength to pull her weight higher and higher. However, mus
Aloiza [94]

Answer:

The correct answer is - It has to act together with the nervous system mainly with other systems that assist in rock climbing.

Explanation:

Rock climbing is a physical activity or sport that could practice indoor or outdoor with mountains. It is a sport that requires physical and mental strength as it requires muscle strength, coordination, or balance, agility, endurance, and mental control over body and mind.

Muscular systems involve pulling the weight of an individual towards and leg muscles to hold whereas the nervous system controls or maintain the actions of muscles and also helps in balance the body of the climber. This neuromuscular set helps in maintains the muscle's tonicity in order to execute the action of climbing.

Other than these two main body systems there are cardiovascular system, circulatory system and respiratory system also helps in providing the conditions like increase oxygen input, high heartbeat, and more.

Amylase is an enzyme that converts carbohydrate polymers into monomers. Glycogen synthase is one of the enzymes involved in conv
ollegr [7]

Answer:

This question is incomplete; the complete part is:

Which of the following best explains the reactions of these enzymes?

A) Amylase aids in the removal of a water molecule to break covalent bonds whereas glycogen synthase aids in the addition of a water molecule to form covalent bonds.

B) Amylase aids in the addition of a water molecule to break covalent bonds whereas glycogen synthase aids in the removal of a water molecule to form covalent bonds.

C) Amylase aids in the addition of a water molecule to form covalent bonds whereas glycogen synthase aids in the removal of a water molecule to break covalent bonds.

D) Amylase aids in the removal of a water molecule to form covalent bonds whereas glycogen synthase aids in the addition of a water molecule to break covalent bonds.

The answer is A

Explanation:

In nature, MONOMERS are simpler units that come together to form larger units called POLYMERS. According to this question, Amylase converts carbohydrate polymers to monomers while Glycogen synthase converts carbohydrate monomers to polymers.

Monomers of carbohydrate are joined together by adding water molecule to form covalent bonds between the monomer units, hence, forming a POLYMER. This is how Glycogen synthase catalyzes its reaction of forming carbohydrate polymer (glycogen).

On the other hand, Amylase breaks down large polymer molecules into monomers by removing water molecules in a process called HYDROLYSIS. This breaks the covalent bond that holds the monomeric units together.

The strand of dna used in the previous problem undergoes a mutation, such that the second c from the 3' end is changed to a
dlinn [17]
This mutation type is a substitution mutation. Substitution mutations may be silent or may have adverse effects (missense mutation).
Adverse effects come about because the change in codons in mRNA transcribed from the DNA strand. A point substitution can change the amino acid being coded for in the particular polypeptide change. If that animo acid is a structural residue of the protein, the structure of the protein will be altered, which may or may not lead to a change in protein function. If that particular amino acid is a catalytic residue of the protein, it may alter the 3D conformation and charge of the active site (if protein is an enzyme) or the binding site of protein. Function of protein formed from mutated DNA will be lost or altered.

Hope this helps! :)

Which molecule listed is most likely to cause osmosis in the body? protein glucose oxygen sodium chloride?
mario62 [17]

The answer is protein

Osmosis happens when the osmotic pressure of two container separated by semipermeable membrane is different. The osmotic pressure could be exert by polar solute because they will attract water molecule. Protein, glucose, and sodium chloride is the common molecule that could cause osmosis. But protein is the main substance that keep the osmotic pressure of the blood in the body.
