In plants, since ABA, a hormone released in response to water desiccation, increases PM19 expression, the overproduction of the membrane protein allow the cells to imbibe the important K+ ion despite the low concentration in the environment.
The DNA sequence of an organism remains constant throughout its life despite the multitude of processes it undergoes by preventing DNA mutations that might alter genetic information, and by ensuring the structural integrity of chromosomes and their orderly transmission to progeny cells. It is necessary to prevent alterations of DNA sequence that may change information encoded in genes because it may cause dysfunction of proteins that are important in the different physiologic activities of the organism.
Proteins are the most significant class of molecules in biochemistry, although of course lipids and carbohydrates are also crucial for all living species whether eukaryotic or prokaryotic such as human, animal, plant and bacteria. Proteins organize and make the basics of life. They control of all actions in each known organisms, for example, the expression of the genetic code, transport of molecules, oxygen and minerals to in or out of the cells, therefore, proteins are responsible for controlling the machinery of cellular which is the phenotype of an organism (Lau, 2005). Moreover, the eukaryotic cell is surrounded by the membrane, which has the control for all substances that can enter in or out of the cell. Although the fundamental structure of membrane is made up by the lipid bilayer, the most particular functions of the plasma membrane are carried out by proteins and provides each sort of membrane a specific feature and characteristic, so under these circumstances the only part of cell that can ...Download file to see next pagesRead More

Analysis MYB26 gene and male sterile and Anther dehiesence

...research is its small genome size. It has only five chromosomes with 157 million base pairs (Bennet et al., 2003) and the genetic and physical maps of all five genes are available. This is useful for genetic sequencing and mapping. In fact the first plant genomes sequenced were of A. thaliana in the year 2000 where 115.4 mega bases of the 125mb genome were sequenced (“Analysis of the genome sequence of the flowering plant Arabidopsis thaliana”, 2000). Such information provides the basis of understanding molecular biology of many plant traits and research has defined the functions of its 27,000 genes and the 35,000 proteins they encode (Integr8, 2011). In...

Yeast Infections

...? Yeast infections are very common and are caused by fungus that can survive anywhere including the human body. The scientific for yeast is Candida. The human body’s immune system usually keeps the amount of yeast infection causing bacteria under control and if the immune is weak (sickness etc) then these bacteria can multiply rapidly and cause yeast infections. A common misconception about yeast infections is that vaginal yeast infections are the only form of yeast infections that occur in the human body. This is certainly not true however and other forms of yeast infections are also very common. These...

The Arabidopsis Myb Genes MYR1 and MYR2

...   The Arabidopsis Myb genes MYR1 and MYR2 are redundant negative regulators of flowering time under decreased lightintensity Flowering of plants is dependent on light intensity, light duration and quality of light. However there has no clear evidence of what actual effects light intensity has on flowering. In this essay I will identify the role of the Myb-Related Protein (MYR1) and Myb-Related Protein (MYR2) as inhibitors of flowering responses on reduced light intensity in Arabidopsis. Arabidopsis is a long day plant that flowers earlier than other plants in long day conditions than in short day conditions. In LD conditions flowering is affected by an increase in expression of the flowering locus T (FT). This gene expression... is...

Protein Quantitation

...? Bradford Protein Concentration Assay The measurement of protein concentrations in aqueous samples is an important assay in biochemistry research and development laboratories for applications such as enzymatic studies and also in providing data for biopharmaceutical lot release. Bradford assays are among the methods used to determine the concentration of protein, relative to a standard. This technique is based on the formation of a complex between the dye, Brilliant Blue G and proteins in solution. The complex being formed causes a shift in the absorption peak from 465nm to 595nm. The following is a report on an experiment conducted to determine protein...

Paper on Arabidopsis cold responses

...? The Effects of Cold Stress on the Cor15a Promoter of Arabidopsis thaliana. Low temperature isamong the most significant environmental factors that influence plant distribution, their growth, their development, and their survival. Plants growing in temperate regions can be able to increase their tolerance of freezing by being exposed to low temperatures, a process called cold acclimation. Key to cold acclimation is low temperature-induced gene expression. Cold acclimation is responsible for the expression of COR (cold-regulated) genes, which encode polypeptides whose function is unknown. It is widely speculated that the products of these genes have roles in freezing tolerance. The aim of...

Protein

...proteins are so important is that they are mad up of amino acids, acids that are necessary for life to function as we know it. While it is true that our bodies can make amino acids by itself, it cannot make all of the amino acids that are needed for life, and must get some of them from the food it consumes. These amino acids thus come from proteins, which should be staples in everybody’s diet. Proteins can come from many different varieties of food, such as meat, egg, grains, and other diary products. These foods are essential to our diet as it is vital to our existence to take these proteins into our bodies so we can use the amino acids they are made...

...Protein Research Protein Research Proteins are complex molecules in the body that perform many vital operations in the body cells. Proteins are made up of micro-amino acids that are required by the body cells for structural formation, functioning and regulation of body tissues and organs( Whitford,2005). Every protein in the body has a unique role ranging from structural support and defense to bodily movement. Proteins are classified according to their body function (Whitford, 2005). Antibodies are specialized proteins that protect the body from foreign invaders in the blood stream, and...

Protein

...Protein Q Describe the alanine-glucose cycle. The alanine-glucose cycle is responsible for the exchange of alanine molecule between skeletal muscles and liver. Like glutamine, alanine is a very important resultant of amino acid degradation that is used in the body. Alanine is the product of transamination of pyruvate that happens in the muscles. From the muscles, the alanine is absorbed in the liver where the process of transamination occurs. The process occurs in the presence of alpha-ketoglutarate. This cycle generates pyruvate which enters the gluconeogenesis cycle and glutamate which enters the urea cycle. The enzyme which is required for these processes to occur is alanine amino transferase. Q 2. List as many...
