MCQs (Multiple Choice Questions)
1) Bioinformatics helps us to understand the whole system of a single cell, in that cell how organelles, genes, proteins, and metabolites are interconnected in a single unified system (cell).
a) False
b) True
Correct Answer:
The correct answer is 'b'.
Explanation:
Bioinformatics is a field of science that uses computational techniques and data analysis to understand how genes, proteins, metabolites, and organelles are interconnected within a single cell and in the broader context of biological systems. It helps researchers study the complex interactions and functions of these components within a cell, making it true that bioinformatics aids in understanding the unified system of a single cell.

2) Bioinformatics helps in studying:
a) Proteomics, Systems Biology
b) All
c) Genomics, Evolutionary Studies
d) None
Correct Answer:
The correct answer is 'b'.
Explanation:
______________________________
3) DNA sends the information to cell via tRNA and that sequence the amino acids according to coded information and protein structure is formed and that protein forms a cell.
b) False
Correct Answer:
The correct answer is 'b'.
Explanation:
The statement is not entirely accurate. DNA carries genetic information and is transcribed into messenger RNA (mRNA). Transfer RNA (tRNA) is responsible for carrying amino acids to the ribosome, where they are then incorporated into a growing protein chain according to the information encoded in the mRNA. Proteins play various roles in a cell, but they don't directly form the entire cell. The formation and functioning of a cell involve many other components and processes beyond just proteins.

4) Central Dogma has following steps:
a) None
b) Transcription from DNA to RNA and Translation from mRNA to Protein
c) Both
d) DNA -> RNA -> Protein
Correct Answer:
The correct answer is 'd'.
Explanation:
The central dogma of molecular biology describes the flow of genetic information in a cell, which involves the sequential processes of DNA replication, transcription (from DNA to RNA), and translation (from mRNA to protein).
______________________________
5) Start Codon is :
a) UAG
b) UGA
c) AUG
d) UAA
Correct Answer:
The correct answer is 'c'.
Explanation:
The start codon, which initiates protein synthesis in most organisms, is represented by the sequence AUG in the mRNA. This codon codes for the amino acid methionine and signals the beginning of translation.
______________________________
6) During cell division each daughter cell receives a copy of the genome of the child cell.
a) False
b) True
Correct Answer:
The correct answer is 'a'.
Explanation:
During cell division, each daughter cell typically receives a copy of the genome of the parent cell. This process ensures that genetic information is passed on to the next generation of cells.
______________________________
7) The formation of a specific RNA from a specific DNA :
a) Reproduction
b) Translation
c) Replication
d) Transcription
Correct Answer:
The correct answer is 'd'.
Explanation:
The formation of a specific RNA molecule from a specific DNA template is called transcription.
______________________________
8) DNA sends the information to cell via mRNA and that sequence the amino acids according to coded information and protein structure is formed and that protein forms a cell:
a) True
b) False
Correct Answer:
The correct answer is 'b'.
Explanation:
The statement is not entirely accurate. DNA carries genetic information and is transcribed into messenger RNA (mRNA). mRNA serves as a messenger that carries the genetic code from DNA to the ribosome. Transfer RNA (tRNA) then brings specific amino acids to the ribosome, and based on the information in mRNA, amino acids are assembled into a protein. Proteins are important components of a cell, but they do not directly form an entire cell. The formation and functioning of a cell involve many other components and processes beyond just proteins.

9) Bioinformatics helps us to understand the systems from small to big like from gene findings to entire system prediction including:
a) Modeling of many biological systems
b) None
c) Protein structure prediction
d) All
Correct Answer:
The correct answer is 'a'.
Explanation:
Bioinformatics indeed helps in understanding various biological systems, from small-scale gene findings to the prediction of entire biological systems. It involves modeling and analyzing a wide range of biological data and processes.
______________________________
10) Multiple types of FASTA exist which are used to align _____ sequences:
a) RNA
b) DNA
c) Protein
d) All of above
Correct Answer:
The correct answer is 'd'.
Explanation:
Multiple types of FASTA formats are used to align DNA, RNA, and protein sequences. FASTA is a flexible and widely used format for representing biological sequences in bioinformatics.
