Minichromosomes can be either linear or circular pieces of DNA. [3] By minimizing the amount of unnecessary genetic information on the chromosome and including the basic components necessary for DNA replication (centromere, telomeres, and replication sequences), molecular biologists aim to construct a chromosomal platform which can be utilized to insert or present new genes into a host cell.
Setaria viridis, emerging model grass for C4 photosynthesis and related bioenergy grasses. [13] [14] Lotus japonicus, model legume used to study the symbiosis responsible for nitrogen fixation. (Agronomy, Molecular biology) Lemna gibba. Lemna gibba, rapidly growing aquatic monocot, one of the smallest flowering plants.
MCM2-7 is required for both DNA replication initiation and elongation; its regulation at each stage is a central feature of eukaryotic DNA replication. [3] During G1 phase, the two head-to-head Mcm2-7 rings serve as the scaffold for the assembly of the bidirectional replication initiation complexes at the replication origin.
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
Genetic engineering techniques allow the modification of animal and plant genomes. Techniques have been devised to insert, delete, and modify DNA at multiple levels, ranging from a specific base pair in a specific gene to entire genes.

The focus of its activities is the genetic engineering of plants. The company is best known for its work in the development of insect -resistant transgenic plants . Its origin goes back to the work of Marc Van Montagu and Jeff Schell at the University of Ghent who were among the first to assemble a practical system for genetic engineering of ...
Many model systems have been developed to better understand interactions between plants and bacterial, fungal, oomycete, viral, and nematode pathogens. A. thaliana has been a powerful tool for the study of the subdiscipline of plant pathology , that is, the interaction between plants and disease-causing pathogens .
