Genome Technology and Engineering - Flash Cards

These flash cards cover important concepts from Genome Technology and Engineering in Biotechnology for Class 12 (Biotechnology).

1/19

What is a genome?

1/19

The genome is the complete genetic information present in the cell of an organism, including DNA in prokaryotes and the DNA in eukaryotic chromosomes.

4/19

What is RFLP?

4/19

RFLP is a mapping technique that involves cutting DNA with restriction enzymes and analyzing the resulting fragment patterns.

5/19

What are STSs?

5/19

Sequence Tagged Sites are unique DNA sequences used as landmarks in physical mapping of genomes, identified by PCR.

6/19

What characterizes first generation DNA sequencing?

6/19

First generation sequencing is a multistep procedure involving DNA fragment separation, restriction digestion, and cloning for sequencing.

7/19

What is next generation sequencing (NGS)?

7/19

NGS uses massively parallel sequencing technology to read millions of DNA fragments simultaneously, enabling rapid sequencing of whole genomes.

8/19

What is Whole Genome Sequencing?

8/19

WGS determines the complete DNA sequence of an organism's genome, useful for understanding genetic disorders and inheritance.

9/19

What is metagenomics?

9/19

Metagenomics studies the collective genetic material from a community of organisms in their natural environment, without culturing them.

10/19

What is CRISPR-Cas9?

10/19

CRISPR-Cas9 is a genome editing technique that uses guide RNA and Cas9 enzyme to create double-strand breaks for precise genetic modifications.

11/19

What are transposons?

11/19

Transposons, or jumping genes, are DNA sequences that can move within a genome, often used for gene knockout and insertion.

12/19

What does functional genomics study?

12/19

Functional genomics aims to understand how gene information is executed physiologically within the organism.

13/19

What is comparative genomics?

13/19

Comparative genomics focuses on comparing genes and genomes across species to identify conserved and unique genes.

14/19

What is high-throughput sequencing?

14/19

High-throughput sequencing allows rapid sequencing of large amounts of DNA, significantly speeding up genomic analysis.

15/19

What is protein engineering?

15/19

Protein engineering involves modifying protein structures to enhance their properties for research and therapeutic applications.

16/19

What are some applications of CRISPR technology?

16/19

CRISPR can be used for gene editing, developing disease-resistant crops, and in gene therapy for treating genetic disorders.

17/19

What is RNA-Seq?

17/19

RNA-Seq is a next-generation sequencing technique used to analyze the transcriptome and gene expression profiles of organisms.

18/19

What are cloning vectors?

18/19

Cloning vectors are DNA molecules used to transport and replicate foreign DNA segments in host cells during cloning.

19/19

What is gene therapy?

19/19

Gene therapy is a technique aimed at correcting defective genes responsible for disease development, often using viral vectors.
