DNA

101
The shape of a DNA molecule.
What is a double helix?
The structure of RNA.
What is single stranded? or What is a single stranded nucleic acid?
This scientist discovered that the amount of adenine in DNA is equal to the amount of thymine, and the amount of cytosine is equal to the amount of guanine.
Who is Erwin Chargaff?
The building blocks of DNA.
What is a nucleotide?
The pair of scientists who discovered the structure of DNA in 1953
Who are Watson and Crick?
The nitrogenous base that replaces thymine in RNA.
What is Uracil?
It describes the orientation of the two strands of DNA, where one strand runs in the 5' to 3' direction and the other runs in the 3' to 5' direction.
What is antiparallel?
This base pairing rule explains how adenine always pairs with thymine, and guanine with cytosine in DNA.
What is complementary base pairing?
These are the four nitrogenous bases in DNA.
What are adenine, thymine, cytosine, and guanine?
The type of RNA that delivers messages outside the nucleus.
What is mRNA?
The type of nitrogenous base, which includes cytosine, thymine, and uracil and has a single-ring structure.
What is a pyrimidine?
The basic unit of heredity, made up of a sequence of DNA that codes for a specific protein or function.
What is a gene?
The type of bond that holds the nitrogenous bases together.
What is a hydrogen bond?
The sugar found in RNA.
What is a ribose?
The award was presented to James Watson, Francis Crick, and Maurice Wilkins for their groundbreaking discovery of the structure of DNA.
What is a Nobel Prize in Medicine?
When pulled out, the chromosome leads to strands of DNA wrapped around to these proteins that help in coiling and organizing the DNA.
What are histones?
The sugar found in DNA.
What is a deoxyribose?
This is where RNA can be found in a cell.
What is a ribosome? What is a cytoplasm?
The technique, used by Rosalind Franklin and later by Watson and Crick, helped reveal the helical structure of DNA. It also allows scientists to observe the arrangement of atoms in the molecule.
What is Crystallography? or What is X-ray Diffraction?
This type of bond connects the phosphate of one nucleotide to the sugar of the next in a DNA strand.
What is a phosphodiester bond?
