The properties of life that plants and animals should possess include heredity and growth, homeostasis, cellular organization, metabolism and responsiveness. Merriam Webster defined the transmission of such qualities from ancestor to descendant through the genes. Therefore, heredity is the power of an organism to reach data about itself onto its young. As well, growth is included as a property of life because all living things originate and some may develop much quicker than others. Another attribute

To all parents, a newborn child is a small miracle, perfect and beautiful in every way. However, in many situations the parents of these miracles learn that their children are “not normal.” Every year 6,000 parents across the country are informed that their child has a genetic disorder called Down Syndrome (“National Down Syndrome Society,” n.d.). Within a matter of minutes parents learn that children with Down Syndrome can also have a variety of other conditions and disorders, will not develop in

Each day, when the sun rises and sets, mammals and plants alike conform together with a celestial rhythm that instructs the activities of the day. The human body, along with nearly all other mammals, endogenously oscillates on a rhythm that coincides with these daily activities. However, when mammals are placed in an environment void of nearly all outside influences, also known as zeitgebers, these rhythms continue to run at specified intervals. Thus, the endogenous rhythm must be governed by an

In HCMV, there are four forms of capsids which are pre-B, B, C and A (Wood et al., 1996). The development of capsids begins with the movement of capsid proteins from the site of synthesis in the cytoplasm to the nucleus where the capsid will be assembled (Gibson, 1996). The capsid shell proteins consist of major capsid protein (MCP), minor capsid protein (mCP), mCP binding protein (mC-BP), and the smallest capsid protein (SCP) (Gibson, 1996). Most of the capsid

In 1886, the first case of Progeria was diagnosed by Dr. Jonathan Hutchinson. Progeria is a pre-mature aging system which is both rare and fatal. He began documenting features of a six year old boy who had symptoms of hair loss and atrophy of skin. Then, in 1897, Dr. Hastings Gilford pronounced Progeria as a clinical entity. The name Progeria comes from the Greek term “progeros" meaning, “prematurely old”. Virtually nothing was known about Progeria 30 years ago. Since it is an extremely rare disease

within humans. 2. Describe the morphology of Chilomastix mesnili trophozoites. In the cyst stage of Chilomastix mesnili, the cyst has a thick wall and is shaped similar to a pear or lemon. It is usually found in the stool. The cyst has a single nucleus located closer to the anterior end as well as other cytoplasmic organelles. During the trophozoite

Discussion In recent years, it has been suggested that miRNAs act as key regulators of gene expression networks. Like other genes, single nucleotide polymorphism in miRNA genes can affects their function at different levels, such as miRNA transcription, maturation and target specificity. Our study is the first report of mir 23a, mir155 and mir 196a2 polymorphism in the iranian MS patients. In this case control study we examined the impact of functional mir 155 rs767649, mir196a2 rs11614913 and

intracellular signal transduction involves the 2 complicated working networks of interacting cytoplasmic signaling pathways and an even more complicated circuit, such as functional interactions rather than contact between physical molecules inside the nucleus. The nuclear circuit includes nuclear receptors, dna binding proteins and epigenetic processes. Genome sequencing variation

Summary on “Pausing guides RNA folding to populate transiently stable RNA structures for riboswitch-based transcription regulation.” Regulation of gene expression is essential for proper functioning of living organisms. In prokaryotes, one of the ways in which gene expression is regulated is by Riboswitches. Riboswitches are are cis-regulatory secondary RNA structures formed in the 5’ UTR( untranslated region) of mRNA and regulate transcription and translation by causing premature termination(Serganov

The nucleus is like the principal.The cell nucleus is a membrane bound structure that contains the cell's hereditary information and controls the cell's growth and reproduction. It is the command center of a eukaryotic cell and is commonly the most prominent organelle in a cell.The cell nucleus is bound by a double membrane called the nuclear envelope. The principal is the person that is control of the school.They make sure that everything is in order and is running like it should be. The mitochondria
