The DNA sequence assembly alone is of little value without additional analysis. [9] Genome annotation is the process of attaching biological information to sequences, and consists of three main steps: [68] identifying portions of the genome that do not code for proteins; identifying elements on the genome, a process called gene prediction, and
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. In early germ line cells, the genome has very low methylation levels. These low levels generally describe active genes.
The process of DNA replication is semiconservative; that is, the copy of the genome inherited by each daughter cell contains one original and one newly synthesized strand of DNA. [ 51 ] : 5.2 The rate of DNA replication in living cells was first measured as the rate of phage T4 DNA elongation in phage-infected E. coli and found to be ...
Genes are made from a long molecule called DNA, which is copied and inherited across generations. DNA is made of simple units that line up in a particular order within it, carrying genetic information. The language used by DNA is called genetic code, which lets organisms read the information in the genes. This information is the instructions ...
Art Nouveau line art. Line art emphasizes form and drawings, of several (few) constant widths (as in technical illustrations), or of freely varying widths (as in brush work or engraving). Line art may tend towards realism (as in much of Gustave Doré's work), or it may be a caricature, cartoon, ideograph, or glyph.
Genome size is the total number of the DNA base pairs in one copy of a haploid genome. Genome size varies widely across species. Genome size varies widely across species. Invertebrates have small genomes, this is also correlated to a small number of transposable elements.
When printed, the human genome sequence fills around 100 huge books of close print. Genome projects are scientific endeavours that ultimately aim to determine the complete genome sequence of an organism (be it an animal, a plant, a fungus, a bacterium, an archaean, a protist or a virus) and to annotate protein-coding genes and other important genome-encoded features.

Transcriptomics technologies are the techniques used to study an organism's transcriptome, the sum of all of its RNA transcripts.The information content of an organism is recorded in the DNA of its genome and expressed through transcription.
