Antiparallel Orientation
The opposite arrangement of the sugar-phosphate backbones in a DNA double helix
Nucleotides
Uracil
One of the four nitrogenous bases, it pairs with Adenine in RNA.
In DNA, Adenine pairs with Thymine while Guanine pairs with Cytosine
Hydrogen Bonding
Attractive force between a hydrogen molecule covalently bonded to an electronegative molecule
Adenine
Nitrogenous base in both RNA and DNA, pairs with Thymine
Forms the structural framework of nucleic acids
Chromosome
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
Nucleic Acids
Purines
One of two types of nitrogenous bases, it is characterized by their two fused rings. The two bases are adenine and guanine
Cytosine
Guanine
mRNA
Ribosomal RNA is a structural part of ribosomes
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.
Gene
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
Thymine
One of the four nitrogenous bases, it pairs with Adenine in DNA.
Chargaff's Rule
tRNA
RNA
A molecule that is essential for the expression of genetic information encoded in DNA and serves as a mediator between DNA and proteins.
DNA
Molecule that carries genetic information
