Can you Describe how the amino acids changes in the protein affect the function of the protein and how this causes disease?
Changes in amino acids can alter the protein's structure, affecting its function by disrupting its binding sites or enzyme activity, leading to disease. For example, in sickle cell anemia, a single amino acid change in hemoglobin causes it to form abnormal-shaped red blood cells, affecting oxygen transport and leading to the disease's symptoms.
How are viruses and prions different?
Prions are infectious agents composed exclusively of a single sialoglycoprotein called PrP 27-30. They contain no nucleic acid. PrP 27-30 has a mass of 27,000 - 30,000 daltons and is composed of 145 amino acids with glycosylation at or near amino acids 181 and 197. The carboxy terminus contains a phosphatidylinositol glycolipid whose components are ethanolamine, phosphate, myo-inositol and stearic acid. This protein polymerizes into rods possessing the ultrastructural and histochemical characteristics of amyloid. Amyloid is a generic term referring to any optically homogenous, waxy, translucent glycoprotein; it is deposited intercellularly and/or intracellularly in many human diseases such as:Alzheimer's diseaseCreutzfeldt-Jakob diseaseDown's syndromeFatal familial insomniaGerstmann-Straussler syndromeKuru LeprosyViroids are infectious agents composed exclusively of a single piece of circular single stranded RNA which has some double-stranded regions.Because of their simplified structures both prions and viroids are sometimes called subviral particles. Viroids mainly cause plant diseases but have recently been reported to cause a human disease.Catalytic RNAs are those that have the intrinsic ability to break and form covalent bonds; Viroids are catalytic RNA's (ribozymes) that cleave RNA to produce fragments containing a 5'-hydroxyl and a 2', 3'-cyclic phosphate.
What is the differences between viriods and prions?
A prion or proteinacious infections particle is simply a protein. They exist as normal proteins in our brain termed PrP, however in certain ecepalopathy diseases these prions are thought to alter shape to a more resistant tertiary protein structure (more beta pleated sheets than alpha helices) and are termed PrPsc. It is theorised the PrPsc are able to convert normal prions to pathogenic ones. Mode of transmission between organisms is unknown as the blood brain barrier should prevent them from getting to the brain of the infected organism. A viriod however is a naked strand of DNA/RNA that causes disease mainly in plants. It does this by cell infection, and then expression of its own genetic code, hijacking the cellular protein synthesis apparatus of the cell to copy itself.
Why does a denature protein no longer function normally?
the function of each protein is a consequence of its specific shape, which is lost when a protein becomes denatured.The shape of a protein determines its specific function within a cell. Denaturing a protein will alter its shape, thus it will no longer function.
What has the ability to alter DNA?
The environment, viruses, and scientists have the ability to alter DNA. These alterations may potentially be passed on to future generations.
What are the exercise and training will alter the?
size coordination and function
What is the function of the cholesteral in the plasma membrane?
alter membrane fluidity
Which fiber alter the microbiota function as a prebiotic?
carrot fiber
What is the four process of an enzyme at work?
Speed, reaction, function, and alter.
How can lymphocyte alter their function in different situations?
It really depends on the situation being studied. A lymphocyte can alter its function and be over productive if the host engages in ritual dance, jazzercise, or attempts to sweat to the oldies.
How does a somatic mutation in a gene alter the function of a cell?
A somatic mutation in a gene can alter the function of a cell by changing the instructions encoded in the gene, leading to abnormal protein production or function. This can disrupt normal cellular processes and potentially contribute to diseases like cancer.
Which fiber is most likely to alter the microbiota function as a prebiotic?
Carrot fiber
