well who better than a texan :D
what you need to analysis about the wall apparently being built here is that it server the purpose of keeping illegals out. or whatever b.s. you believe on either side of these people. what other thing to note is that it costs us lots of money, its stretches across the entirety of south texas which is about ohhh : 1,954 mi or, 3,145 kilometers. scaling the best would be near impossible as it reaches a more than a few feet in the air. so reaching your hands up to touch the top like a little kid is pointless. as it is about: 21 feet (6.4 m) tall and 6 feet (1.8 m) deep in the ground, cemented in a 3-foot (0.91 m)-wide trench with 5,000 psi (345 bar; 352 kg/cm²) concrete. so don't even try it. if you need more info then ask and ill be glad to inform you.
When you decide to work with a construction manager, one of the reasons why you do so is because of the expertise they bring to the project. Effective construction managers have a high degree of expertise with the entire process of bringing a construction project to completion. Before going further, let’s define what we mean by expertise. What we mean is that in order to be effective, a construction manager must have a high degree of familiarity with each aspect of a construction project.
(Hoped this helped UwU)
Answer:
The study of the cell cycle focuses on mechanisms that regulate the timing and frequency of DNA duplication and cell division. As a biological concept, the cell cycle is defined as the period between successive divisions of a cell. During this period, the contents of the cell must be accurately replicated. Microscopists had known about cell division for more than one hundred years, but not until the 1950s, through the pioneering work of Alma Howard and Stephen Pelc, did they become aware that DNA replication took place only at a specific phase of the cell cycle and that this phase was clearly separated from mitosis. Howard and Pelc's work in the broad bean, Vicia faba, revealed that the cell goes through many discrete phases before and after cell division. From this understanding, scientists then identified the four characteristic phases of the cell cycle: mitosis (M), gap 1 (G1), DNA synthesis (S), and gap 2 (G2). The study of these phases, the proteins that regulate them, and the complex biochemical interactions that stop or start DNA replication and cell division (cytokinesis) are the primary concerns of cell cycle biologists.
The most significant progress in this research field came with the demonstration that specific protein complexes involving cyclins were critical for regulating the passage of cells through the cell cycle. These early observations came from biological studies of the cells of rapidly dividing fertilized frog eggs as well as mutant yeast cells that could not divide. The observations suggested that regulation of the cell cycle is conserved throughout eukaryotes, which has since proved to be the case. The mechanism of division in bacteria differs from that of eukaryotes, and the control of their cell cycle is also somewhat different, although again it is linked with DNA replication.
Although the cell cycle is a highly integrated process, distinct areas of interest within this field of study have emerged. For instance, many genes and proteins that influence the passage from one phase of the cell cycle to another have been identified. When their expression is altered by mutation or aberrant regulation, they are usually classed as oncogenes. Other proteins act to hold the cell at distinct points in the cycle (checkpoints) and are known as tumor suppressor genes. Apart from those with a clearly regulatory role, many proteins have important functions in other aspects of the cell cycle; one is replication of DNA and organelles, which is a fascinating process that includes its own repair mechanisms and self-editing. Other fields focus primarily on the mechanical processes of cell cleavage into two daughter cells at the end of mitosis and on the condensation and decondensation of chromatin.
