A gene cluster is a group of two or more genes found within an organism's DNA that encode similar polypeptides or proteins which collectively share a generalized function and are often located within a few thousand base pairs of each other.
An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
Since air plants bloom just once, producing offsets is a nifty way for the parent plant to preserve its DNA and produce new air plants even in the absence of pollinators.
A homeobox is a DNA sequence, around 180 base pairs long, that regulates large-scale anatomical features in the early stages of embryonic development. Mutations in a homeobox may change large-scale anatomical features of the full-grown organism.
Plants depend on epigenetic processes (mechanisms that regulate gene activity and expression without changing the underlying DNA sequence) for proper function. [1] The area of study examines protein interactions with DNA and its associated components, including histones and various other modifications such as methylation , which alter the rate ...
Each eukaryotic ribosomal cluster contains the 5' external transcribed spacer (5' ETS), the 18S rRNA gene, the ITS1, the 5.8S rRNA gene, the ITS2, the 26S or 28S rRNA gene, and finally the 3' ETS. [5] During rRNA maturation, ETS and ITS pieces are excised. As non-functional by-products of this maturation, they are rapidly degraded. [6]
Germplasm bank of the Instituto Nacional de Tecnología Agropecuaria.. Germplasm refers to genetic resources such as seeds, tissues, and DNA sequences that are maintained for the purpose of animal and plant breeding, conservation efforts, agriculture, and other research uses.
The ribosomal DNA (abbreviated rDNA) consists of a group of ribosomal RNA encoding genes and related regulatory elements, and is widespread in similar configuration in all domains of life. The ribosomal DNA encodes the non-coding ribosomal RNA , integral structural elements in the assembly of ribosomes , its importance making it the most ...
