Answer:
The correct answer is "Identical copies of the original DNA would not be formed".
Explanation:
Hydrogen bonding between nitrogenous bases in DNA is one of the characteristics that makes unique the sequences of DNA. This is known as complementary base pairing, at which in regular conditions cytosine could only bind with guanine by forming three hydrogen bonds, and adenine with thymine by forming two hydrogen bonds. If hydrogen bonds could be formed between any two nitrogenous bases in DNA, the formation of identical copies of the original DNA would not be possible. DNA polymerase identifies the next nucleotide during polymerization by complementary base pairing, if this mechanism did not exist DNA polymerase would not be able to make identical copies of DNA.

Answer & explanation:
The Monera kingdom is formed by cyanobacteria (photosynthetic bacteria) and archaebacteria (also called archaea), all living beings of simple structure, prokaryotic and unicellular.
However, the term "monera" is obsolete in the current classification of kingdoms. The beings that were part of the monera kingdom began to be divided between the Bacteria and Archaea kingdoms.
The Bacteria kingdom represents the largest number of species containing bacteria and cyanobacteria, while the Archaea kingdom has a smaller number of species.
Archeas are no longer classified as bacteria because they have structures that make them closer to eukaryotes (although they are prokaryotes).
Despite this new division, some more simplified books still use the term "monera".
A catalyst accelerates a chemical reaction in a cell.
A catalyst is a substance that increases the rate of a chemical reaction without undergoing any permanent chemical change itself.
Catalysts work by lowering the activation energy required for a reaction to occur. Activation energy is the energy barrier that must be overcome for a reaction to proceed.
By reducing the activation energy, a catalyst makes it easier for reactant molecules to come together and undergo chemical transformations, ultimately speeding up the reaction.
Catalysts are essential in biological systems as they enable various biochemical reactions to occur at the relatively mild conditions found inside cells, which would otherwise require higher temperatures or longer reaction times without catalysis.
In cells, enzymes are the most common type of catalysts. Enzymes are highly specific protein molecules that catalyze specific biochemical reactions, ensuring the efficient and precise functioning of cellular processes.

Explanation:
The blood is a specialized body fluid that functions as a transport medium within an animal's body. The fluid transports and supplies the body with essential substances such as nutrient and oxygen as well as removal of toxic wastes from the body.
The blood is made up of two main components;
