  2. Genomic DNA - Wikipedia

    en.wikipedia.org/wiki/Genomic_DNA

    Most organisms have the same genomic DNA in every cell; however, only certain genes are active in each cell to allow for cell function and differentiation within the body. [2] gDNA predominantly resides in the cell nucleus packed into dense chromosome structures. Chromatin refers to the combination of DNA and proteins that make up chromosomes.

    en.wikipedia.org/wiki/Introduction_to_genetics

    DNA can be copied very easily and accurately because each piece of DNA can direct the assembly of a new copy of its information. This is because DNA is made of two strands that pair together like the two sides of a zipper. The nucleotides are in the center, like the teeth in the zipper, and pair up to hold the two strands together.

    A major step toward that goal was the completion in 2007 of the full genome of James D. Watson, one of the co-discoverers of the structure of DNA. [20] Whereas a genome sequence lists the order of every DNA base in a genome, a genome map identifies the landmarks.

    en.wikipedia.org/wiki/DNA

    DNA is a long polymer made from repeating units called nucleotides. [6] [7] The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. [8] In all species it is composed of two helical chains, bound to each other by hydrogen bonds.

    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

    The animations have a non-descript musical background and are purposely not narrated to maximize use. These animations may be played alone or simultaneously with the spoken definition of the term. All cellular organelles have animation sequences, as do many key terms such as gene, cell, ACGT, and chromosome. Spoken Explanations of Glossary Terms:

  9. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    The total length of the human reference genome does not represent the sequence of any specific individual, nor does it represent the sequence of all of the DNA found within a cell. The human reference genome only includes one copy of each of the paired, homologous autosomes plus one copy of each of the two sex chromosomes (X and Y).
