Questions and Answers

What is the primary purpose of creating transgenic organisms?

To reduce the number of chromosomes in organisms

To promote natural evolution of species

To eliminate the need for asexual reproduction in organisms

To generate organisms with improved characteristics, such as resistance to pests or diseases (correct)

Which of the following best describes a transgenic organism?

An organism that has been genetically modified through the insertion of genes from another species (correct)

An organism that has undergone asexual reproduction

An organism that has naturally evolved to have specific genetic traits

Study Notes

Transgenic Organisms

Primary purpose of creating transgenic organisms is to introduce new traits or enhance existing traits for agricultural, medical, or scientific purposes.
Transgenic organisms are defined as those that have had genes from a different species inserted into their genome.
They differ from traditionally bred organisms, which involve the selective breeding of varieties within the same species to enhance desired traits, without introducing foreign DNA.

PCR (Polymerase Chain Reaction)

Main purpose of PCR is to amplify small segments of DNA, making millions of copies for analysis or research.
PCR stands for Polymerase Chain Reaction.
Critical enzyme in the PCR process is DNA polymerase, which synthesizes new strands of DNA.
Function of PCR includes amplifying DNA for various applications such as cloning, gene expression analysis, and forensic analysis.
Taq polymerase is commonly used in PCR due to its ability to withstand high temperatures required for DNA denaturation.
PCR contributes to genetic research by enabling scientists to analyze specific genes, study genetic variations, and conduct genetic mapping swiftly and efficiently.
