One of two types of nitrogenous bases, it is characterized by their two fused rings. The two bases are adenine and guanine
Sugar-Phosphate Backbone
Forms the structural framework of nucleic acids
Base Pairing Rules
In DNA, Adenine pairs with Thymine while Guanine pairs with Cytosine
rRNA
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
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
DNA
Molecule that carries genetic information
Messenger RNA is a type of RNA that carries genetic information from the DNA in the nucleus to the cytoplasm
Attractive force between a hydrogen molecule covalently bonded to an electronegative molecule
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.
The opposite arrangement of the sugar-phosphate backbones in a DNA double helix
One of the four nitrogenous bases, it pairs with Adenine in DNA.
Adenine
Nitrogenous base in both RNA and DNA, pairs with Thymine
Chargaff's Rule
There are equal amounts of Adenine to Thymine and Guanine to Cytosine
Guanine
Uracil
RNA
A molecule that is essential for the expression of genetic information encoded in DNA and serves as a mediator between DNA and proteins.
Organic molecules that play essential roles regarding genetic information
tRNA
Transfer RNA transports amino acids to the ribosome during protein synthesis
Nucleotides
Building blocks of DNA and RNA
Cytosine
Nitrogenous base in both RNA and DNA, pairs with Guanine
