<h3>Answer#1
</h3><h2>(B) Replication
</h2><h3>Explanation:
</h3>
Prior to the division of cell, the DNA is replicated in a way that the pair strands of a DNA molecule have corresponding base sets, the nucleotide order of each strand unanimously satisfies the data required to produce its duplicate. The process of replication is to divide a cell into two and form a two new cells with child DNA.
<h3>Answer#2
</h3><h2>(A) Unwinding the double helix
</h2><h3>Explanation:
</h3>
The initial start in DNA replication is the unwinding of the pair DNA strands that make up the helix that is to be replicated. DNA Helicase untwists the helix at positions called replication origins. The replication origin produces a Y pattern and is named as a replication fork.
<h3>Answer#3
</h3><h2>(A) Repair the DNA
</h2>
Meanwhile DNA construction, maximum DNA polymerases "review their performance," getting the bulk of mis-paired bases in a method called proofreading. Shortly after DNA synthesis, any left mis-paired bases can be identified and substituted in a procedure called mismatch repair. If DNA gets destroyed, it can be fixed by different mechanisms, including chemical repeal, excision restoration, and double-stranded break repair.
<h3>Answer#4
</h3><h2>(C) p53
</h2><h3>Explanation:
</h3>
p53, also identified as TP53 or tumor protein is a gene that codes for a protein that coordinates the cell sequence and therefore operates as a tumor suppression. It is quite essential for cells in multi cellular bodies to overcome cancer. p53 has also been defined as "the protector of the genome" because of its function in maintaining stability by limiting genome variation.
<h3>Answer#5
</h3><h2>(D) nRNA
</h2><h3>Explanation:
</h3>
nRNA is not part of protein synthesis as Ribosomal RNA (rRNA) connects with a collection of proteins in order to produce ribosomes. These composite formations, which physically move along an mRNA molecule, fastens the construction of amino acids into protein series. They also compel tRNAs and several assistant molecules which are required for protein construction.

</h3><h3>Answer#6
</h3><h2>(A) The making of a new DNA molecule by pairing the bases of DNA nucleotide with complementary bases in an existing DNA molecule
</h2>
The above mentioned answer explains the process of replication in which a double-stranded DNA unit is duplicated to create two same DNA molecules. DNA replication is an example of the most fundamental methods that happen within a cell. Every time a cell splits, the pair emerging daughter cells carry accurately the same genetic data, or DNA, as the parent cell.
<h3 /><h3>Answer#7 </h3><h2>(C) 3</h2>
A codon is a series of three nucleotides which collectively produce a segment of genetic code in a DNA or RNA molecule. There are in total three bases in a codon. Three nucleotide bases which present a codon also define which amino acid appears next in the series.
<h3>Answer#8</h3><h2>(B) Tertiary</h2>
The secondary structure begins the folding up process where as in the tertiary structure, the protein is folded into its accurate 3D structure, associating to the purpose. This is tied together by a series of non-covalent communications between side groups, including ionic communications, disulphide bonds, hydrophobic interactions, Van der Waals energies and hydrogen bonds.
<h3>Answer#9</h3><h2>(D) Replicator</h2>
Proteins performs the function of binding different bacteria and viruses as an antibody. Also, as an enzyme they carry out all the chemical reactions through out body. And lastly, they act as a messenger and helps in the communication between various cells, tissues and organs called as growth hormone. The only function that proteins does not perform is of replication.
<h3>Answer#10</h3><h2>(C) It is not used up</h2>
Enzymes are very effective in fastening up biochemical reactions. They can catalyze up to several million responses per second. As a result to which, the variation in speeds of biochemical reactions with and without enzymes may be immense. A normal biochemical reaction possibly take hours or regular days to happen under typical cellular conditions without an enzyme, but fewer than a second including the enzyme.
