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