Summary
This study introduces a color-enhanced Ambiscript notation for nucleic acid sequences. This new graphic representation improves the visualization of nucleotide frequencies and polymorphisms in alignments.
Area of Science:
- Bioinformatics
- Computational Biology
- Genomics
Background:
- Ambiscript notation uses symbol symmetries for nucleic acid analysis.
- Original Ambiscript lacks representation of nucleotide frequency distributions in consensus sequences.
- Polymorphisms in consensus sequences require enhanced visualization methods.
Purpose of the Study:
- To develop a color-augmented ambigraphic notation for nucleic acid sequences.
- To encode the frequency of positional polymorphisms in consensus sequences.
- To improve the analysis of multiple sequence alignments.
Main Methods:
- Implemented a color-coding approach using an Adobe Flash application.
- Modified Ambiscript characters are shaded and colored based on nucleotide prevalence.
- The application visualizes palindromes and inverted repeats in DNA motifs.
Main Results:
- Developed a color-augmented Ambiscript notation for nucleic acid sequences.
- The graphic representation effectively displays nucleotide frequency and polymorphisms.
- Enhanced visualization aids in perceiving biologically-relevant patterns in alignments.
Conclusions:
- Color-augmented Ambiscript notation enhances information content and functionality.
- The notation combines color, shading, and character symmetries for improved analysis.
- This approach aligns with graphic excellence principles for scientific data visualization.

Nucleic Acid Structure
8.1K
The pentose sugar in DNA is deoxyribose, while in RNA the pentose sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the ribose's second carbon and a hydrogen on the deoxyribose's second carbon. The phosphate residue attaches to the hydroxyl group of the 5′ carbon of one sugar and the hydroxyl group of the 3′ carbon of the sugar of the next nucleotide, which forms a 5′ to 3′ phosphodiester linkage.

Conservation of Protein Domains Over Different Proteins
11.8K
Protein domains are small structurally independent units that are part of a single amino acid chain. Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Multi-species Conserved Sequences
3.3K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

DNA as a Genetic Template
22.2K
Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...
