  2. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    Epigenetic markers strengthen and weaken transcription of certain genes but do not affect the actual sequence of DNA nucleotides. DNA methylation is a major form of epigenetic control over gene expression and one of the most highly studied topics in epigenetics. During development, the human DNA methylation profile experiences dramatic changes.

  3. Genomics - Wikipedia

    en.wikipedia.org/wiki/Genomics

    Genomics is an interdisciplinary field of molecular biology focusing on the structure, function, evolution, mapping, and editing of genomes.A genome is an organism's complete set of DNA, including all of its genes as well as its hierarchical, three-dimensional structural configuration.

  4. Gene mapping - Wikipedia

    en.wikipedia.org/wiki/Gene_mapping

    There are two distinctive mapping approaches used in the field of genome mapping: genetic maps (also known as linkage maps) [7] and physical maps. [3] While both maps are a collection of genetic markers and gene loci, [8] genetic maps' distances are based on the genetic linkage information, while physical maps use actual physical distances usually measured in number of base pairs.

  5. Personal genomics - Wikipedia

    en.wikipedia.org/wiki/Personal_genomics

    Personal genomics or consumer genetics is the branch of genomics concerned with the sequencing, analysis and interpretation of the genome of an individual. The genotyping stage employs different techniques, including single-nucleotide polymorphism (SNP) analysis chips (typically 0.02% of the genome), or partial or full genome sequencing.

  6. DNA sequencing - Wikipedia

    en.wikipedia.org/wiki/DNA_sequencing

    DNA sequencing may be used along with DNA profiling methods for forensic identification [21] and paternity testing. DNA testing has evolved tremendously in the last few decades to ultimately link a DNA print to what is under investigation. The DNA patterns in fingerprint, saliva, hair follicles, etc. uniquely separate each living organism from ...

  8. DNA and RNA codon tables - Wikipedia

    en.wikipedia.org/wiki/DNA_and_RNA_codon_tables

    [2] [3] The mRNA sequence is determined by the sequence of genomic DNA. [4] In this context, the standard genetic code is referred to as translation table 1. [3] It can also be represented in a DNA codon table. The DNA codons in such tables occur on the sense DNA strand and are arranged in a 5 ′-to-3 ′ direction.

  9. Genetic genealogy - Wikipedia

    en.wikipedia.org/wiki/Genetic_genealogy

    Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable.
