Adenine
Nitrogenous base in both RNA and DNA, pairs with Thymine
Antiparallel Orientation
The opposite arrangement of the sugar-phosphate backbones in a DNA double helix
One of the four nitrogenous bases, it pairs with Adenine in RNA.
They are segments of DNA that contain the instructions for building proteins, which are essential for the structure, function, and regulation of the body's cells, tissues, and organs
tRNA
Transfer RNA transports amino acids to the ribosome during protein synthesis
Ribosomal RNA is a structural part of ribosomes
Building blocks of DNA and RNA
Messenger RNA is a type of RNA that carries genetic information from the DNA in the nucleus to the cytoplasm
Thread-like structures made of DNA and proteins found in the nucleus of most living cells. They carry genetic information in the form of genes
Pyrimidines
One of the two types of nitrogenous bases, They are characterized by a six-membered ring structure composed of four carbon atoms and two nitrogen atoms.The two bases are thymine and cytosine.
Molecule that carries genetic information
Chargaff's Rule
There are equal amounts of Adenine to Thymine and Guanine to Cytosine
Sugar-Phosphate Backbone
Forms the structural framework of nucleic acids
Nucleic Acids
RNA
A molecule that is essential for the expression of genetic information encoded in DNA and serves as a mediator between DNA and proteins.
Cytosine
Nitrogenous base in both RNA and DNA, pairs with Guanine
Thymine
One of the four nitrogenous bases, it pairs with Adenine in DNA.
Base Pairing Rules
Hydrogen Bonding
Attractive force between a hydrogen molecule covalently bonded to an electronegative molecule
Guanine
Nitrogenous base in both RNA and DNA, pairs with Cytosine
Purines
One of two types of nitrogenous bases, it is characterized by their two fused rings. The two bases are adenine and guanine
