A consensus logo is a simplified variation of a sequence logo that can be embedded in text format. Like a sequence logo, a consensus logo is created from a collection of aligned protein or DNA/RNA sequences and conveys information about the conservation of each position of a sequence motif or sequence alignment [1] [4].
The score is greater than 0 if it is more likely to be a functional site than a random site, and less than 0 if it is more likely to be a random site than a functional site. [1] The sequence score can also be interpreted in a physical framework as the binding energy for that sequence.
A DNA sequence motif represented as a sequence logo for the LexA-binding motif.. In biology, a sequence motif is a nucleotide or amino-acid sequence pattern that is widespread and usually assumed to be related to biological function of the macromolecule.
Some broadcasters that have ceased signing on and signing off in favour of 24-hour broadcasting may perform a sign-off sequence at a certain time in the night (usually between 10:00 p.m. and 1:00 a.m.) as a formality to signify the end of its operating day (in the United States, the broadcast logging day ends at 12:00 midnight local time).
[2] Any mutation allowing a mutated nucleotide in the core promoter sequence to look more like the consensus sequence is known as an up mutation. This kind of mutation will generally make the promoter stronger, and thus the RNA polymerase forms a tighter bind to the DNA it wishes to transcribe and transcription is up-regulated.

Thus, the first digit (line 2) is multiplied by 1, the second by 2, the third by 4, the fourth by 8 and so on, until the 10th, which is multiplied by 512. The sum of all these numbers modulo 11 is the check digit. [13] The code on the caboose in the picture at top can be decoded as Start 8350199918 Stop 5.
This is a code number from 0 to 4, with 0, 1 and 2 meaning data is included, and 3 and 4 indicating no precipitation data. i X is a code number indicating the manner of station operation, and the format used in group 7wwWW; codes 1, 2 and 3 indicate a manned station, while codes 4 to 7 indicate an automatic station.
