The modern apple has 17 chromosomes which were found to be derived from an ancestor with 9 chromosomes that experienced genome-wide duplication. The genome sequence also provided proof that Malus sieversii was the wild ancestor of the domestic apple—an issue that had been long-debated in the scientific community.
An apple is a round, edible fruit produced by an apple tree (Malus spp., among them the domestic or orchard apple; Malus domestica). Apple trees are cultivated worldwide and are the most widely grown species in the genus Malus. The tree originated in Central Asia, where its wild ancestor, Malus sieversii, is still found.
The mitosis process in the cells of eukaryotic organisms follows a similar pattern, but with variations in three main details. "Closed" and "open" mitosis can be distinguished on the basis of nuclear envelope remaining intact or breaking down. An intermediate form with partial degradation of the nuclear envelope is called "semiopen" mitosis.
It's hard to believe that apple cider was more popular than beer at one time, but there are a lot of core truths about apples you might not be aware of.
The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.
Cell division in prokaryotes (binary fission) and eukaryotes (mitosis and meiosis). The thick lines are chromosomes, and the thin blue lines are fibers pulling on the chromosomes and pushing the ends of the cell apart. The cell cycle in eukaryotes: I = Interphase, M = Mitosis, G 0 = Gap 0, G 1 = Gap 1, G 2 = Gap 2, S = Synthesis, G 3 = Gap 3.
Apple's first CEO, Michael Scott, gave us a bunch of color on the early days, and Steve Wozniak helped with a list of early employees, though it was based on his memory. We got our full list from ...
For instance, wild apples were found to have multiple blue mold resistant genes, specifically against Penicillium expansum. [24] The USDA Plant Genetic Resources Unit (PGRU) also conducted phenotypic analysis on M. sieversii seedlings, and has identified various pathogenic resistance including apple scab , fire blight , and cedar apple rust ...
