A correspondence between open reading frames in sense and antisense strands is expected from the hypothesis that the prototypic triplet code was of general form RNY, where R is a purine base, N is any base, and Y is a pyrimidine. The similar Codon frequencies found in sense and antisense strands can be attributed to the wide distribution of inverted repeats stem-loop potential in natural DNA sequences.

Previous efforts to characterize conservation between the human and mouse genomes focused largely on sequence comparisons. These studies are inherently limited because they don't account for gene structure differences, which may exist despite genomic sequence conservation.

Sense in antisense?

Sugarcane is an important sugar and energy crop that can be used efficiently for biofuels production. The development of sugarcane cultivars tolerant to drought could allow for the expansion of plantations to sub-prime regions. Knowledge on the mechanisms underlying drought responses and its relationship with carbon partition would greatly help to define routes to increase yield. In this work we studied sugarcane responses to drought using a custom designed oligonucleotide array with 21, different probes. The oligoarrays were designed to contain probes that detect transcription in both sense and antisense orientation. Among them, were sense transcripts and 59 were antisense transcripts. Our custom sugarcane oligonucleotide array provides sensitivity and good coverage of sugarcane transcripts for the identification of a representative proportion of natural antisense transcripts NATs and sense-antisense transcript pairs SATs.

The enzymes involved in transcription are called RNA polymerases. Prokaryotes have one type; eukaryotes have three types of nuclear RNA polymerases. The prokaryotic RNA polymerase consists of a core enzyme and an auxiliary protein factor called sigma s factor. The core consists of four subunits, two are identical, a , the other two similar, b and b '. The b ' subunit binds the DNA while the b subunit binds the nucleotides that are to be joined together to form the RNA molecule. Sigma factors function in identifying specific DNA sequences known as promoters.

Identification of sense and antisense transcripts regulated by drought in sugarcane

The antisense strand is thus responsible for the RNA that is later translated to protein, while the sense strand possesses a nearly identical makeup to that of the mRNA. Note that for each segment of double stranded DNA, there will possibly be two sets of sense and antisense, depending on which direction one reads since sense and antisense is relative to perspective. It is ultimately the gene product, or mRNA, that dictates which strand of one segment of dsDNA we call sense or antisense. But keep in mind that sometimes, such as in prokaryotes, overlapping genes on opposite strands means the sense for one mRNA can be the antisense for another mRNA. The immediate product of this transcription is a resultant initial RNA transcript, which contains a sequence of nucleotides that is identical to that of the sense strand. The exception to this is that uracil is used for nucleotide sequencing of RNA molecules rather than thymine. Most eukaryotic RNA transcripts undergo additional editing prior to being translated for protein synthesis.

Над ними, опираясь на перила площадки перед своим кабинетом, стоял Стратмор. Какое-то время в здании слышался только неровный гул расположенных далеко внизу генераторов. Сьюзан отчаянно пыталась встретиться взглядом со Стратмором. Коммандер. Северная Дакота - это Хейл.


​Antisense​​ Antisense can also refer to a method for silencing genes. To silence a target gene, a second gene is introduced that produces an mRNA complementary to that produced from the target gene. These two mRNAs can interact to form a double-stranded structure that cannot be used to direct protein synthesis.

Он должен быть. Дворик под названием Апельсиновый сад прославился благодаря двум десяткам апельсиновых деревьев, которые приобрели в городе известность как место рождения английского мармелада.

То была моль, севшая на одну из плат, в результате чего произошло короткое замыкание. Тогда-то виновников компьютерных сбоев и стали называть вирусами. У меня нет на это времени, - сказала себе Сьюзан.

Он это отлично знает. Стратмор провел рукой по вспотевшему лбу. - Этот шифр есть продукт нового типа шифровального алгоритма, с таким нам еще не приходилось сталкиваться. Эти слова повергли Сьюзан в еще большее смятение. Шифровальный алгоритм - это просто набор математических формул для преобразования текста в шифр.

Опустив руки, он незаметными быстрыми движениями соединял кончики пальцев. Перед его глазами появилось сообщение, которое он должен был отправить. ТЕМА СООБЩЕНИЯ: П. КЛУШАР - ЛИКВИДИРОВАН Он улыбнулся.

The sense strand is considered as the coding strand of the double strand DNA, which runs from 5'.

Although genome-wide transcriptional analysis has been used for many years to study bacterial gene expression, many aspects of the bacterial transcriptome remain undefined.

Antisense is the non-coding DNA strand of a gene.
