Repeated in Biological Definition

Microsatellite

... (a Tandemly Repetitive DNA sequence) that is repeated many times within the genome of an ... at the same locus. In a microsatellite, the repeated sequence is very simple, consisting of two to four nucleotides, and can be repeated 10 to 100 times. Hence if one sequenced a ...

Polymerase chain reaction

... to develop a process by which DNA could be artificially multiplied through repeated cycles of duplication driven by an enzyme called DNA polymerase . ... Step 4 Elongation. Heat at 72C for 45 seconds. Step 5 Steps 2-4 are repeated 25 times, but with good primers and fresh polymerase, 15 to 20 cycles is ...

Y chromosome

... 2003 was that the Y chromosome exchanges genes between the two copies of repeated sequences that lie near to each other as mirror images. This phenomenon is ... observed on a small scale over long evolutionary timescales between repeated sequences on the same chromosome, but not at the dramatic frequency ...

Anatomy

... parts, such as the brain or viscera, contenting themselves with a good working knowledge of the rest. Topographical anatomy must be learned by repeated dissection and inspection of dead human bodies. It is no more a science than a pilot's knowledge is, and, like that knowledge, must be exact and ...

Bone

... in shape and occurs throughout a person's life. Its purpose is the release of calcium and the repair of micro-damaged bones (from everyday stress). repeated stress results in the bone thickening at the points of maximum stress. It has been hypothesized that this is a result of bone's piezoelectric ...

Charles Darwin

... get around to proposing, but did tell her of his ideas on transmutation. His thoughts and work continued in London over the autumn and he suffered repeated bouts of illness, then on 11 November he returned and proposed to Emma. Again he discussed his ideas, and she subsequently wrote beseeching him to ...

Diabetes mellitus

... metabolism, and indeed the existence of insulin, was not fully clarified until 1921 , when Sir Frederick Grant Banting and Charles Herbert Best repeated the work of Von Mering and Minkowski but went a step further and managed to show that they could reverse the induced diabetes in dogs by giving them ...

Photosynthesis

... had been "injured" by the candle and the mouse could be restored by a plant. In 1778 , Jan Ingenhousz , court physician to the Austrian Empress, repeated Priestley's experiments. He discovered that it was the influence of sun and light on the plant that could cause it to rescue a mouse in a matter of ...

Long-term potentiation

... YY, Kandel ER (1994) "Recruitment of long-lasting and protein kinase A-dependent long-term potentiation in the CA1 region of hippocampus requires repeated tetanization". Learn Mem 1 (1), 74-82. ^ Kojima N, Wang J, Mansuy IM, Grant SG, Mayford M, Kandel ER (1997) "Rescuing impairment of ...

Polysaccharide

... from cellulose . Wood is largely cellulose and lignin , while paper and cotton are nearly pure cellulose. Cellulose is a polymer made with repeated glucose units bonded together by beta- linkages. Humans and many other animals lack an enzyme to break the beta- linkages, so they do not digest ...

Primer

... The 5'-hydroxyl of the new nucleotide is blocked by DMT, preventing the addition of more than one nucleotide to each chain. After that, the cycle is repeated for each nucleotide in the primer. This is a simplified description, the actual process is quite complicated. For that reason, most laboratories do ...

Repeated sequence (DNA)

... In the study of DNA sequences, one can distinguish two main types of repeated sequence : Tandem repeats : Satellite DNA , Minisatellite , Microsatellite ; Interspersed repeats : SINE ( S hort IN ...

Replication

... same page of the memory - which usually means, that each node have separate copy (replica) of this page. In statistics replication refers to repeated measurement of a phenomenon, so that the variability can be estimated. In science , this is a synonym for Reproducibility . ...
