- Alternative splicing is a regulatory mechanism by which variations in the incorporation of the exons, or coding regions, into mRNA leads to the production of more than one related protein, or isoform. A process in which the introduction of double-stranded RNA into a cell inhibits the expression of genes.

- INC | DNA Domains | Home Page. DNA sequencing is any process used to map out the sequence of the nucleotides that comprise a strand of DNA. This website is meant as a primer to show you, step by step, what parts of DNA are being 'sequenced' and why it is such a valuable process for humankind to learn.

- A common procedure for DNA fingerprinting is restriction fragment length polymorphism (RFLP). In this method, DNA is extracted from a sample and cut into segments using special restriction enzymes.RFLP focuses on segments that contain sequences of repeated DNA bases, which vary widely from person to person.n this method, DNA is extracted from a sample and cut into segments using special restriction enzymes.

DNA profiling DNA profiling (also called DNA fingerprinting, DNA testing, or DNA typing) is a forensic technique used to identify individuals by characteristics of their DNA.lthough 99.9% of human DNA sequences are the same in every person, enough of the DNA is different that it is possible to distinguish one individual from another, unless they are monozygotic (identical) twins.

- Definition. Homologous recombination is the exchange of DNA strands of similar or identical nucleotide sequence. It can be used to direct error-free repair of double-strand DNA breaks and generates sequence variation in gametes during meiosis.

RNA splicing In molecular biology, splicing is the editing of the nascent pre-messenger RNA (pre-mRNA) transcript. After splicing, introns are removed and exons are joined together (ligated). For nuclear-encoded genes, splicing takes place within the nucleus either co-transcriptionally or immediately after transcription.

Splice site mutation From Wikipedia, the free encyclopedia. A splice site mutation is a genetic mutation that inserts, deletes or changes a number of nucleotides in the specific site at which splicing of an intron takes place during the processing of precursor messenger RNA into mature messenger RNA.rom Wikipedia, the free encyclopedia.

- A mechanism by which different forms of mature mRNAs are generated from the same gene. Alternative splicing is a regulatory mechanism by which variations in the incorporation of the exons, or coding regions, into mRNA leads to the production of more than one related protein, or isoform.

DNA profiling DNA profiling (also called DNA fingerprinting, DNA testing, or DNA typing) is a forensic technique used to identify individuals by characteristics of their DNA. DNA profile is a small set of DNA variations that is very likely to be different in all unrelated individuals, thereby being as unique to individuals as are fingerprints (hence the alternate name for the technique).

Sticky and blunt ends DNA ends refer to the properties of the end of DNA molecules, which may be sticky ends, blunt ends or in other forms. The concept is used in molecular biology, especially in cloning or when subcloning inserts DNA into vector DNA. Such ends may be generated by restriction enzymes that cut the DNA – a staggered cut generates two sticky ends, while a straight cut generate blunt ends. A sticky or cohesive end has protruding single-stranded strands with unpaired nucleotides called overhangs ...

Definitions &Translations DNA profiling (also called DNA testing, DNA typing, or genetic fingerprinting) is a technique employed by forensic scientist s to assist in the identification of individuals by their respective DNA profiles.NA profiles are encrypted sets of numbers that reflect a person's DNA makeup, which can also be used as the person's identifier. DNA profiling should not be confused with full genome sequencing. It is used in, for example, parent testing and criminal investigation.

Key points: DNA cloning is the process of making multiple, identical copies of a particular piece of DNA. In a typical DNA cloning procedure, the gene or other DNA fragment of interest (perhaps a gene for a medically important human protein) is first inserted into a circular piece of DNA called a plasmid.

DNA profiling DNA profiling (also called DNA fingerprinting, DNA testing, or DNA typing) is a forensic technique used to identify individuals by characteristics of their DNA. In 1992, DNA from a palo verde tree was used to convict Mark Alan Bogan of murder. 2  DNA from seed pods of a tree at the crime scene was found to match that of seed pods found in Bogan's truck. 3  This is the first instance of plant DNA admitted in a criminal case.

3-D Animation Library Transcription & Translation: RNA Splicing. Transcript: As DNA is transcribed into RNA it needs to be edited to remove non-coding regions, or introns, shown in green. This editing process is called splicing, which involves removing the introns, leaving only the yellow, protein-coding regions, called exons.

3-D Animation Library 3-D Animation Library. Transcription & Translation: RNA Splicing. In some genes the protein-coding sections of the DNA (exons) are interrupted by non-coding regions (introns). RNA splicing removes the introns from pre mRNA to produce the final set of instructions for the protein.

Who Invented Gene Splicing? Scientists can then add DNA sequences (i.e. a particular gene of interest) to this exposed strand using an enzyme called DNA ligase. When the DNA strand is repaired this recombinant DNA will create the protein product of the new gene. Any form of DNA can be spliced together, no matter what its origin. For example, human insulin-producing genes have been spliced into plasmids.

- A technique used especially for identification (as for forensic purposes) by extracting and identifying the base-pair pattern of an individual's DNA -- called also DNA typing, genetic fingerprinting. Definition from: Merriam-Webster's Medical Dictionary by Merriam-Webster Inc.NA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect.

RNA splicing The term intron refers to both the DNA sequence within a gene and the corresponding sequence in the unprocessed RNA transcript. As part of the RNA processing pathway, introns are removed by RNA splicing either shortly after or concurrent with transcription.
