15 Questions
What are the three main forms of RNA?
mRNA, rRNA, tRNA
What is the universal triplet code in genetics?
The genetic code
What are the basic elements of gene regulation?
Promoter, operator regions
What are the monomers of a polypeptide chain?
Amino acids
Which organelles are involved in the export of proteins via the secretory pathway?
Rough endoplasmic reticulum, Golgi apparatus
What is the role of CRISPR-Cas9 in bacteria?
Editing organism's genome
Explain the steps involved in gene expression in eukaryotic cells.
Transcription, RNA processing, and translation by ribosomes.
Describe the structure of genes, including exons, introns, and promoter and operator regions.
Genes contain exons (coding regions), introns (non-coding regions), and regulatory regions like promoters and operators.
What are the hierarchical levels of structure that give rise to a functional protein?
Primary, secondary, tertiary, and quaternary structures.
Explain the function of enzymes in biochemical pathways.
Enzymes act as catalysts to speed up chemical reactions in biochemical pathways.
How do rough endoplasmic reticulum, Golgi apparatus, and vesicles contribute to protein export from a cell?
Rough ER synthesizes proteins, Golgi modifies and packages them, and vesicles transport them to the cell membrane for export.
What is the function of CRISPR-Cas9 in editing an organism's genome?
CRISPR-Cas9 is used to precisely edit DNA sequences in an organism's genome.
How is DNA amplified using polymerase chain reaction (PCR)?
PCR involves cycles of denaturation, annealing, and extension to amplify specific DNA sequences.
Explain the use of gel electrophoresis in sorting DNA fragments.
Gel electrophoresis separates DNA fragments based on size by applying an electric field through a gel matrix.
How are genetically modified and transgenic organisms used in agriculture?
They are used to increase crop productivity and provide resistance to diseases.
Test your knowledge on nucleic acids, DNA structure, RNA forms, genetic code, gene expression steps, gene structure, exons, introns, and promoter and operator regions.
