Dna Sequence in a sentence

Bio-IT World 2011 Assembly main render Sequence assembly refers to aligning and merging fragments of a much longer DNA sequence in order to reconstruct the original sequence.

For example, in transcription, when a cell uses the information in a gene, the DNA sequence is copied into a complementary RNA sequence through the attraction between the DNA and the correct RNA nucleotides.

New DNA may be inserted in the host genome by first isolating and copying the genetic material of interest using molecular cloning methods to generate a DNA sequence, or by synthesizing the DNA, and then inserting this construct into the host organism.

Recombinant DNA is a man-made DNA sequence that has been assembled from other DNA sequences.

An insulator in a DNA sequence is comparable to a linguistic word divider such as a comma (,) in a sentence, because the insulator indicates where an enhanced or repressed sequence ends.

By impact on protein sequence *A frameshift mutation is a mutation caused by insertion or deletion of a number of nucleotides that is not evenly divisible by three from a DNA sequence.

The term exon refers to both the DNA sequence within a gene and to the corresponding sequence in RNA transcripts.

A mutation is a tiny alteration that occurs to genetic materials like our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors.

Methylation represents a chemical change that can activate or repress a segment of DNA without altering the DNA sequence.

A Southern blot is a method used in molecular biology for detection of a specific DNA sequence in DNA samples.

Before a cell divides, the DNA is copied, so that each of the resulting two cells will inherit the DNA sequence.

Each spot has a DNA fragment molecule that is complementary to a single DNA sequence (similar to Southern blotting).

Epigenetic modifications are reversible modifications on a cell’s DNA or histones that affect gene expression without altering the DNA sequence (Russell 2010 p. 475).

Mutagens may also modify the DNA sequence; the changes in nucleic acid sequences by mutations include substitution of nucleotide base-pairs and insertions and deletions of one or more nucleotides in DNA sequences.

Result Hybridization of the probe to a specific DNA fragment on the filter membrane indicates that this fragment contains DNA sequence that is complementary to the probe.

The DNA sequence may be aligned with other DNA sequences to identify homologous sequences and locate the specific mutations that make them distinct.

The HapMap is a haplotype map of the human genome, "which will describe the common patterns of human DNA sequence variation." citation It catalogs the patterns of small-scale variations in the genome that involve single DNA letters, or bases.

The N-terminal DNA binding domain (labeled) of the lac repressor binds its target DNA sequence (gold) in the major groove using a helix-turn-helix motif.

The transcription factor wraps around the DNA helix and uses its fingers to accurately bind to the DNA sequence.

Analyses of DNA sequence evolution found evidence of strong natural selection on BLT in Physaria.
