It is important to recognise the difference so you can identify where children need help or may be at risk of having SEN 7 people found this useful What is the difference between developed and developing? Developed is past tense which means that it has already occurred, whereas developing is present continuous tense and refers something happening currently. With regard to world economies, the distinction is that developed countries have a higher level of production and per capita income than countries defined as developing less developed.
The sequence of the DNA of a living thing encodes the necessary information for that living thing to survive and reproduce. Therefore, determining the sequence is useful in fundamental research into why and how organisms live, as well as in applied subjects.
Because of the importance of DNA to living things, knowledge of a DNA sequence may be useful in practically any biological research. For example, in medicine it can be used to identify, diagnose and potentially develop treatments for genetic diseases. Similarly, research into pathogens may lead to treatments for contagious diseases.
Biotechnology is a burgeoning discipline, with the potential for many useful products and services.
RNA is not sequenced directly. Current sequencing methods rely on the discriminatory ability of DNA polymerases, and therefore can only distinguish four bases.
With current technology, it is difficult to sequence small amounts of DNA, as the signal is too weak to measure. This is overcome by polymerase chain reaction PCR amplification. Digital representation[ edit ] Genetic sequence in digital format.
Once a nucleic acid sequence has been obtained from an organism, it is stored in silico in digital format. Digital genetic sequences may be stored in sequence databasesbe analyzed see Sequence analysis belowbe digitally altered and be used as templates for creating new actual DNA using artificial gene synthesis.
Sequence analysis Digital genetic sequences may be analyzed using the tools of bioinformatics to attempt to determine its function. Genetic testing The DNA in an organism's genome can be analyzed to diagnose vulnerabilities to inherited diseasesand can also be used to determine a child's paternity genetic father or a person's ancestry.
Normally, every person carries two variations of every geneone inherited from their mother, the other inherited from their father. The human genome is believed to contain around 20, - 25, genes. In addition to studying chromosomes to the level of individual genes, genetic testing in a broader sense includes biochemical tests for the possible presence of genetic diseasesor mutant forms of genes associated with increased risk of developing genetic disorders.
Genetic testing identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person's chance of developing or passing on a genetic disorder.
Several hundred genetic tests are currently in use, and more are being developed. Sequence alignment In bioinformatics, a sequence alignment is a way of arranging the sequences of DNARNAor protein to identify regions of similarity that may be due to functional, structuralor evolutionary relationships between the sequences.
In sequence alignments of proteins, the degree of similarity between amino acids occupying a particular position in the sequence can be interpreted as a rough measure of how conserved a particular region or sequence motif is among lineages.
The absence of substitutions, or the presence of only very conservative substitutions that is, the substitution of amino acids whose side chains have similar biochemical properties in a particular region of the sequence, suggest  that this region has structural or functional importance.
Although DNA and RNA nucleotide bases are more similar to each other than are amino acids, the conservation of base pairs can indicate a similar functional or structural role. The degree to which sequences in a query set differ is qualitatively related to the sequences' evolutionary distance from one another.
Roughly speaking, high sequence identity suggests that the sequences in question have a comparatively young most recent common ancestorwhile low identity suggests that the divergence is more ancient. This approximation, which reflects the " molecular clock " hypothesis that a roughly constant rate of evolutionary change can be used to extrapolate the elapsed time since two genes first diverged that is, the coalescence timeassumes that the effects of mutation and selection are constant across sequence lineages.
Therefore, it does not account for possible difference among organisms or species in the rates of DNA repair or the possible functional conservation of specific regions in a sequence.
In the case of nucleotide sequences, the molecular clock hypothesis in its most basic form also discounts the difference in acceptance rates between silent mutations that do not alter the meaning of a given codon and other mutations that result in a different amino acid being incorporated into the protein.
More statistically accurate methods allow the evolutionary rate on each branch of the phylogenetic tree to vary, thus producing better estimates of coalescence times for genes.Difference between windows and windows , Difference between windows and , Print Server, Active Directory , Windows Server , Window.
