Which genetic change causes alterations in only one or a few nucleotide bases?

Answers

Answer 1

The genetic change causes alterations in only one or a few nucleotide bases in known as mutation.

A mutation is a change in a brief section of a genome's nucleotide sequence. Another frequently replaces one nucleotide in point mutations; other changes involve the insertion or deletion of one or more nucleotides.

Errors in DNA replication or the harmful effects of mutagens, such as chemicals and radiation, which react with DNA and alter the architecture of individual nucleotides, are the leading causes of mutations.

DNA repair enzymes are present in all cells and work to reduce the frequency of mutations. These enzymes reduce genetic information loss, double-strand break formation, and DNA crosslinking by repairing DNA damage.

The hydrophobicity plot assigns each amino acid a hydrophobic value based on the method by kyte and doolittle. What can be inferred from the plot?

Answers

The hydrophobicity plot tells us about the location of transmembrane helices.

What is hydrophobicity plot?Hydrophobicity plots are used to predict the location of turns in proteins.In 1982, Kyte and Doolittle gave a hydrophobicity scale which gives each amino acid a hydrophobicity value.A hydrophobicity plot is drawn between the residue number versus residue hydrophobicity. These hydropathy plots are used to determine the transmembrane helices of proteins.The transmembrane helices are present in the non polar area (hydrophobic) of the lipid membrane whereas the other parts are present in polar areas (hydrophilic).Thus by computing the hydrophobicity value and plotting it on a graph we can find the loops and turns in proteins. Nowadays there are many hydrophobicity scales determining the hydrophobicity value of amino acids.

What term is used to describe a solution of lower osmolarity compared to one with a higher osmolarity?

Answers

When two solutions have different osmolarity, the solution with lower osmolarity is called hypoosmotic

What is osmolarity?

The term osmolarity defines the total concentration of solute particles present in a particular volume of solution.

If a solution has a high amount of solute particles in one litre of solution, this solution is termed to have high osmolarity. If a solution has a low amount of solute particles per litre of solution, it is said to have low osmolarity.

When comparing two solutions of different osmolarities, the solution with higher osmolarity will be called hypertonic and the solution with lower osmolarity is called hypotonic.

Therefore, the term used to describe a solution of lower osmolarity compared to a solution of higher osmolarity is hypotonic.

Conventional genetic analyses of prions involving rrna sequences are impossible because?

Answers

Conventional genetic analyses of prions involving rrna sequences are impossible because Prions do not contain nucleic acids

The name "prions" refers to aberrant, pathogenic agents that are transmissible and capable of inducing improper folding of specific normal cellular proteins known as prion proteins, which are abundant in the brain.

Prions are virus-like creatures that contain a prion protein. These elongated fibrils (green) are thought to be protein aggregations from the infectious prion. Prions cause neurodegenerative brain illness by attacking nerve cells. Symptoms of "mad cow" include glassy eyes and uncontrollable bodily trembling.

Prion disorders develop when normal prion protein, which is found on the surface of many cells, becomes aberrant and clumps in the brain, causing harm to the brain.

Conventional genetic analyses of prions involving rrna sequences are impossible because Prions do not contain nucleic acids.

Prions are misfolded proteins that have the ability to transmit their misfolded shape onto normal variants of the same protein. They characterize several fatal and transmissible neurodegenerative diseases in humans and many other animals. It is not known what causes a normal protein to misfold, but the resulting abnormal three-dimensional structure confers infectious properties by collapsing nearby protein molecules into the same shape.

The word prion is derived from the term, "proteinaceous infectious particle". In comparison to all other known infectious agents such as viroids, viruses, bacteria, fungi, and parasites, all of which contain nucleic acids (DNA, RNA, or both), the hypothesized role of a protein as an infectious agent stands in contrast.

Prion isoforms of the prion protein (PrP), whose specific function is uncertain, are hypothesized as the cause of transmissible spongiform encephalopathies (TSEs), including scrapie in sheep, chronic wasting disease (CWD) in deer, bovine spongiform encephalopathy (BSE) in cattle (commonly known as "mad cow disease") and Creutzfeldt–Jakob disease (CJD) in humans.

All known prion diseases in mammals affect the structure of the brain or other neural tissue; all are progressive, have no known effective treatment, and are always fatal. Until 2015, all known mammalian prion diseases were caused by the prion protein (PrP); however, in 2015 it was hypothesized that multiple system atrophy (MSA) was caused by a prion form of alpha-synuclein.

Prions are a type of intrinsically disordered protein, which change their conformation unless they are bound to a specific partner such as another protein. With a prion, two protein chains are stabilized if one binds to another in the same conformation. The probability of this happening is low, but once it does the combination of the two is very stable. Then more units can get added, making a sort of "fibril". Prions form abnormal aggregates of proteins called amyloids, which accumulate in infected tissue and are associated with tissue damage and cell death. Amyloids are also responsible for several other neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease.

In response to a specific stimulus, autonomic reflex arcs can trigger smooth muscle contraction, cardiac muscle contraction and secretion by glands.

An element of the peripheral nervous system that controls unconscious physiological functions is the autonomic nervous system. The reflex arc is a unique kind of neural circuit that starts with a sense neuron at a receptor (for instance, a pain receptor in the fingertip) and ends with a motor neuron at an effector (e.g., a skeletal muscle).

In a humid-temperate climate such as that of pennsylvania or washington, dc, weathering breaks down granite to produce?

Answers

In a humid-temperate climate such as that of Pennsylvania or Washington, dc, weathering breaks down granite to produce Quartz sand, clay, and rust, that stay to help make soil, while some ions dissolve and wash away.

 

Weathering of granite in Pennsylvania or Washington DC or other places where abundant rain falls makes some things (clay, rust, and quartz sand) that stay behind to contribute to soil, and other things (soluble ions) that dissolve and wash away very quickly.

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion.

Weathering is often divided into the processes of mechanical weathering and chemical weathering

Biological weathering, in which living or once-living organisms contribute to weathering, can be a part of both processes. Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble. Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation.

The body makes less pee when its antidiuretic hormone level is high. A low level causes more urine to be produced. Water is retained, blood volume rises, and symptoms such as nausea, headaches, confusion, lethargy, and low blood sodium may occur if there is too much antidiuretic hormone.

The kidneys will secrete too much water because of low anti-diuretic hormone levels. Dehydration and a drop in blood pressure will result from an increase in urine output. antidiuretic hormone is a chemical that is created in the hypothalamus, a region of the brain.
