Translation (biology) In biology, translation is the process in living cells in which proteins are produced using RNA molecules as templates. The generated protein is a sequence of amino acids. This sequence is determined by the sequence of nucleotides in the RNA. The nucleotides are considered three at a time.
By convention, the coding strand is the strand used when displaying a DNA sequence. It is presented in the 5' to 3' direction. Wherever a gene exists on a DNA molecule, one strand is the coding strand (or sense strand), and the other is the noncoding strand (also called the antisense strand, [3] anticoding strand, template strand or transcribed ...
Nick translation [1] (or head translation), developed in 1977 by Peter Rigby and Paul Berg, is a tagging technique in molecular biology in which DNA Polymerase I is used to replace some of the nucleotides of a DNA sequence with their labeled analogues, creating a tagged DNA sequence which can be used as a probe in fluorescent in situ hybridization (FISH) or blotting techniques.
The replication fork is a structure that forms within the long helical DNA during DNA replication. It is produced by enzymes called helicases that break the hydrogen bonds that hold the DNA strands together in a helix. The resulting structure has two branching "prongs", each one made up of a single strand of DNA.
Histone code. The histone code is a hypothesis that the transcription of genetic information encoded in DNA is in part regulated by chemical modifications (known as histone marks) to histone proteins, primarily on their unstructured ends. Together with similar modifications such as DNA methylation it is part of the epigenetic code. [1]
Adapter (genetics) An adapter or adaptor, or a linker in genetic engineering is a short, chemically synthesized, single-stranded or double-stranded oligonucleotide that can be ligated to the ends of other DNA or RNA molecules. Double stranded adapters can be synthesized to have blunt ends to both terminals or to have sticky end at one end and ...
Gene delivery. Gene delivery is the process of introducing foreign genetic material, such as DNA or RNA, into host cells. [ 1 ] Gene delivery must reach the genome of the host cell to induce gene expression. [ 2 ] Successful gene delivery requires the foreign gene delivery to remain stable within the host cell and can either integrate into the ...
A eukaryotic cell has a nucleus that separates the processes of transcription and translation. Eukaryotic transcription occurs within the nucleus where DNA is packaged into nucleosomesand higher order chromatinstructures. The complexity of the eukaryotic genome necessitates a great variety and complexity of gene expression control.
