The genomes of RNA viruses can be either single-stranded RNA or double-stranded RNA, and may contain one or more separate RNA molecules (segments: monopartit or multipartit genome). DNA viruses can have either single-stranded or double-stranded genomes. Most DNA virus genomes are composed of a single, linear molecule of DNA, but some are made ...
This requires first making a duplicate copy of every gene in the genome in a process called DNA replication. [51]: 5.2 The copies are made by specialized enzymes known as DNA polymerases, which "read" one strand of the double-helical DNA, known as the template strand, and synthesize a new complementary strand.
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
Here, the single-stranded DNA curls around in a long circle stabilized by telomere-binding proteins. [68] At the very end of the T-loop, the single-stranded telomere DNA is held onto a region of double-stranded DNA by the telomere strand disrupting the double-helical DNA and base pairing to one of the two strands.

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 ...
Not even our own spell check recognizes the word, quickly underlining "spaghetto" in bold red squiggles. The tweet quickly went viral, with nearly 19,000 people expressing similar shock. this woke ...
An organism's genome is made up by its entire set of DNA and is responsible for its genetic traits, function and development. The composition of DNA itself is an essential component to the field of molecular genetics; it is the basis of how DNA is able to store genetic information, pass it on, and be in a format that can be read and translated ...
