This set of Basic Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Genetics – Antisense and RNA Interference”.
1. Which among the mentioned terms in diagram determine to describe all the proteins encoded by the genome?
a) Plant cells
b) Genomics
c) Proteomics
d) Viruses
View Answer
Explanation: Proteomics determine to describe all the proteins encoded by the genome. It is including their structure and localization. In humans it also includes their abundance, interactions and modifications.
2. The proteome is infinity more complex than the genome.
a) True
b) False
View Answer
Explanation: The proteome is infinity more complex than the genome. The sum total of genetic information of an organism is called as genome. The collective body of proteins made within an organism’s cells or tissues is proteome.
3. How many genomes can a cell have?
a) 1
b) 12
c) 26
d) 75
View Answer
Explanation: A cell can have only one genome. Because the genetic composition remains the same. It does not vary.
4. A cell can have only one proteome.
a) True
b) False
View Answer
Explanation: A cell can have many proteomes. DNA alphabet is composed of four bases. But in case of proteins it varies.
5. Proteins are constructed from approximately how many amino acids?
a) 140
b) 100
c) 60
d) 20
View Answer
Explanation: Proteins are constructed from approximately 20 amino acids. That is why a cell can have variable number of proteomes. These amino acids are further classified.
6. Genes determine the sequence of amino acids and form proteins through ______________
a) Transcription
b) Translation
c) Replication
d) Self-duplication
View Answer
Explanation: Genes to proteins is called translation. DNA to DNA synthesis is replication. DNA to RNA is transcription.
7. Which among the mentioned terms in diagram supplies the recipe for making the cell’s proteins?
a) Plant cells
b) Genome
c) Proteomics
d) Viruses
View Answer
Explanation: The genome supplies the recipe for making the cell’s proteins. Genes code the genetic information. The sum total of genetic information of an organism is called as genome.
8. Proteins have which kind of structures?
a) Folded 3D
b) Linear
c) Non-linear 2D
d) Trapezoidal
View Answer
Explanation: Proteins have folded structures. These are three dimensional. Genes are linear structures.
9. Which technique is used for the separation, mapping and quantification of protein?
a) 2D PAGE
b) Gene gun
c) Biolistic
d) R-DNA technology
View Answer
Explanation: 2D PAGE is used for the analysis of protein. This technique is used for the separation, mapping and quantification of proteins. Electrophoresis is of various types.
10. Which among the mentioned terms in diagram represents the brick and mortar of cell and carries out the metabolic functions?
a) Plant cell
b) Genomics
c) Proteome
d) Viruses
View Answer
Explanation: Proteome represents the brick and mortar of cell. It carries out the metabolic functions. Proteomics determine to describe all the proteins encoded by the genome.
11. 2D PAGE can be expanded as _________
a) 2-dimensional polyacrylamide gel electrophoresis
b) 2D polyamide glucosyl ethanoate
c) 2-dimensional polyacrylamide gene electrophoresis
d) 2-dimensional polyamide gene electrophoresis
View Answer
Explanation: 2D PAGE can be expanded as 2-dimensional polyacrylamide gel electrophoresis. It separtes, maps and quantifies proteins. It is a type of gel electrophoresis.
12. Genes can be silenced by means of ______
a) Glycolysis
b) Antisense technology
c) Genomics
d) Proteomics
View Answer
Explanation: Genes can be silenced by means of antisense technology. Antisense gene can be constructed. It can be done by reversing nucleotide sequence of gene.
