A1.2.8 Complementary base pairing in allowing genetic information to be replicated and expressed Flashcards
What is Watson-Crick base pairing?
The specificity of base pairing that forms the foundation of DNA’s double helix structure.
What is the role of complementary base pairing in error prevention?
It ensures accurate copying of genetic information and allows for error detection.
What is complementary base pairing in DNA?
A mechanism where specific DNA bases fit together to store and replicate genetic information.
What happens during transcription?
DNA serves as a template to produce RNA, replacing Thymine (T) with Uracil (U).
What practical applications arise from understanding complementary base pairing?
It is essential for designing PCR primers, DNA sequencing, genetic engineering, and understanding genetic diseases.
What is the first step in DNA replication?
The DNA double helix unwinds.
What does each strand of DNA serve as during replication?
Each strand serves as a template for creating new strands.
Why are C-G pairs more stable than A-T pairs?
C-G pairs have an extra hydrogen bond, making them harder to separate.
How does complementary base pairing maintain genetic integrity?
It preserves genetic information and ensures accurate DNA replication and gene expression.
What is the significance of G-C bonds in PCR?
The strength of G-C bonds is important for processes like PCR, where DNA needs to be separated and rejoined.
How does base pairing influence DNA’s physical properties?
It creates the double helix shape and provides stability to the DNA molecule.
What is the result of DNA replication?
Two identical DNA molecules are formed.
How do scientists design primers for PCR?
They create primers that are complementary to specific DNA sequences they want to amplify.
