DNA Flashcards
DNA Stands for?
Deoxyribonucleic Acid
Is a group of molecules that is responsible for carrying and transmitting the hereditary materials or the genetic instructions from parents to offspring
DNA
It is a long molecule made up of monomers called
Nucleotides
The basic building blocks of nucleic acids (DNA and RNA)
Nucleotides
It is the backbone of DNA, which is formed by alternating sugar and phosphates held together by a strong bond

He is a swiss biologist that first recognized and identified DNA during his research on white blood cells in 1869
Johannes Friedrich Miescher
In 1953, they concluded that the DNA molecule appears as a three-dimensional double helix (which resembles a twisted ladder)

They used X-ray crystallography to study DNA’s structure, which helped Watson and Crick with their discovery
