Amplified fragment length polymorphism (AFLP-PCR or AFLP) is a PCR-based tool used in genetics research, DNA fingerprinting, and in the practice of genetic engineering. Developed in the early 1990s by Pieter Vos, [ 1 ] AFLP uses restriction enzymes to digest genomic DNA , followed by ligation of adaptors to the sticky ends of the restriction ...
DNA profiling databases in Plants: PIDS: PIDS(Plant international DNA-fingerprinting system) is an open source web server and free software based plant international DNA fingerprinting system. It manages huge amount of microsatellite DNA fingerprint data, performs genetic studies, and automates collection, storage and maintenance while ...
[9] [10] These two cells are very different, and give rise to different structures, establishing polarity in the embryo. apical cell The small apical cell is on the top and contains most of the cytoplasm, the aqueous substance found within cells, from the original zygote. [11] It gives rise to the hypocotyl, shoot apical meristem, and ...
The cell cycle, or cell-division cycle, is the sequential series of events that take place in a cell that causes it to divide into two daughter cells. These events include the growth of the cell, duplication of its DNA ( DNA replication ) and some of its organelles , and subsequently the partitioning of its cytoplasm, chromosomes and other ...
S phase (Synthesis phase) is the phase of the cell cycle in which DNA is replicated, occurring between G 1 phase and G 2 phase. [1] Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved.
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.
One key issue is the ownership of an individual's DNA and the data produced when that DNA is sequenced. [173] Regarding the DNA molecule itself, the leading legal case on this topic, Moore v. Regents of the University of California (1990) ruled that individuals have no property rights to discarded cells or any profits made using these cells ...
Indeed, in Xenopus embryos in which excess DNA is introduced, transcription begins earlier. [5] [8] More recently, evidence has been shown that transcription of a subset of genes in Drosophila is delayed by one cell cycle in haploid embryos. [9] The second mechanism of repression has also been addressed experimentally.
