chromosomes) that revealed its tumor origin. Plasticity of a mother cell: · Totipotent: capable of generating a complete organism, plus the tissues of the placenta or trophoblast (only the Moral4) · Pluripotent: capable of forming all the cells of an organism, but not the extra embryonic tissues (blastocyte, CEG, CMC and the CMAR, although it is not known if all can). · Multipotent: capable of generating various types of cells, but only those found within its germinal line of origin (they are found in adipose tissue, bone marrow, etc.) · Unipotent: generate specific cells (osteoblasts, osteocytes). Embryonic stem cells There is a big problem with respect to the CME and has to do with...

chromosome, it is a disease that regularly only affects men, although women can be carriers or show symptoms. Approximately 33% of children born with Duchenne dystrophy do not have family precedents, this may be because the gene suffers from some spontaneous mutation. This disease appears by mutations in the dystrophin gene. Dystrophin is a structural protein found in the cytoplasm of muscle cells and its function is to tie plasma proteins to the cell membrane. Dystrophin loss leads to muscle fibers being transformed into adipose cells. Physiologically muscle fibers have a fusiform and polynucleated type, cell membrane is known as sarcolema and cytosol is known as sarcoplasma. Muscle fibers are...
chromosome with loss of genetic material, they produce an abnormal phenotype due to the loss of genes. Deletions with several base pairs constitute a fraction of spontaneous mutations Spontaneous lesions Spontaneous lesions also cause mutations, the most frequent are purification and discouragement. DEPURINATIONS Training occurs spontaneously and is a consequence of the loss of a nucleotide purine base resulting in an apurine site. During the replication, the apurine sites do not specify any base, but in some cases a base can be inserted in that site and that sometimes generates a mutation. DESANIMATION OF THE C DISANIMINATION IS THAT SPANNIOUS ALTERATION THAT AN AMINO GROUP OF A BASE, THE...
chromosomes Introduction The process by which the cells originate is called a cell division. According to one of the postulates of cell theory, new cells only originate from other living cells. So that the cell can be divided, the genome must also do so. Millions of bone marrow cells or the digestive tract of the human being are being divided at all times. The production of these cells is of great importance to replenish old or dead cells. Cell division occurs in all organisms and is a different process in eukaryotes and prokaryotes. Developing In prokaryotes and eukaryotes, cell division produces two equal daughter cells from a progenitor cell. When an eukaryotic cell is divided asexually the...
chromosomes you have. Goes in your birth certificate. Gender is much more complex. It is a social and legal status, and a set of expectations of society, on behaviors, characteristics and thoughts. Each culture has standards about the way people must behave according to their gender. This is also generally masculine or female. But instead of dealing with body parts, it's more about how you are expected to act, due to your sex. Gender identity is how you feel inside and how you express your gender through clothes, behavior and personal appearance. It is a feeling that begins very early in life. What is the assigned sex (also known as ‘biological sex’)? The assigned sex is a label that is given...
chromosomes. The first thing we should know is that all the cells of our body have a total of 46 chromosomes These cells as they receive the name somatic cells are 46 chromosomes are grouped are grouped into 23 pairs, 23 gives us our mother and 23 our father. We must know that the exception to the rule is sexual cells, the cells that we provide to leave our offspring. In men the sexual cell is sperm, while in women the mature sex cell is the ovule and each of these more of having 46 chromosomes has only half that would be 23. Haploidía as a concept we define it as the number of complete chromosomes games in 1 cell, in the human being the haploid number is 23 chromosomes, we have 23 chromosomes is...

chromosome 17 of the protein gene containing P97/Valosin on chromosome 9 and that of the chMP2b protein of chromosome 3, which are associated with the atrophy of pathology of the pathology. Chemically speaking the disorder is explained by the alteration of neurotransmitter gestures such as cholinergic, serotonergic, dopaminergic, noradrenergic and glutamericics, all involved in the demential picture. DFT variants In this pathology there are three clinical variants such as frontal variant, semantic dementia and non -fluent progressive aphasia: Front variant (VF): represents 90% of DFT cases and their frequent manifestations are the early deterioration of social behavior, decreased regulation of...
chromosome and whose genetic heritage can be located. They are widely used in genetic mapping as the first step to find the position and identity of a gene. Valadez, e. And Günter, K. These programs for pepper cultivation will be carried out through the selection of plants from existing populations (germplasm). Always the development of a new variety will be very striking for the consumer as to the high performance parameters of the fruit, colorful and erect fruit. For genetic improvement, a good selection of parents must be done, thereby guaranteeing the success of our genetic improvement. However, a disadvantage of this is that the costs it requires are the time used, so it is considered a long...
chromosome, which can give the beginning of various diseases that are transmitted from parents to children, either by an abnormal number of the chromosome or by genetic modifications, in this case it is foundpresent an abnormal gene that modifies the function of the dystrophin protein which is responsible for connecting the actin filaments with the extracellular matrix and lacking this or that an anomaly is found in it affects the relationship between the matrix and the layerFine of the cell which seriously causes that muscle fiber cells disappear and are replaced with adipose tissue, that is, with fatty tissue. In general, this abnormal gene only affects men while women become carriers, which is why...

chromosomes. Normally, the core of each cell contains 23 pairs of chromosomes, half of which are inherited from each parent (father and mother). But in the case of a child with Down syndrome, it does not have that same process in the there is an error in the cell division called ‘non -disjunction’ that results in an embryo with three copies of chromosome 21 instead of the usual two. Before or in the conception, a couple of chromosomes 21 In the sperm or the ovule cannot separate, as the embryo develops, the extra chromosome is replicated in each cell of the body there are other types of expression of said genetic mutation as is the case of mosaicism that occurs when non -disjunction of...
