Question

Одна цепь участка ДНК,выделенной из кишечной палочки,имеет последовательность нуклеотидов ЦЦЦАТТГГТАГЦЦТА.Допустим.Что с этой ДНК транскрибируется иРНК,причем матрицей служит комплементарная цепь.Какой будет последовательность иРНК?

Answer 1

ДНК: 1 цепь:ЦЦЦ     АТТ     ГГТ  АГЦ    ЦТА
        2 цепь:ГГГ        ТАА    ЦЦА  ТЦГ     ГАТ
      и-РНК:ЦЦЦ          АУУ   ГГУ    АГЦ    ЦУА

Answer 2

DNA Transcription and RNA Sequence

When DNA is transcribed into RNA, the process involves creating a complementary RNA strand based on the DNA template strand. In this case, the given DNA sequence is ЦЦЦАТТГГТАГЦЦТА. To determine the RNA sequence, we need to identify the complementary bases for each nucleotide in the DNA sequence.

In DNA, the bases are adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, thymine is replaced by uracil (U). The complementary bases are as follows:

- A (adenine) pairs with U (uracil) - C (cytosine) pairs with G (guanine) - G (guanine) pairs with C (cytosine) - T (thymine) pairs with A (adenine)

Therefore, the complementary RNA sequence for the given DNA sequence ЦЦЦАТТГГТАГЦЦТА would be:

ГГГУААССАУЦГГА

Please note that the given DNA sequence contains non-standard characters (Ц). Assuming that Ц represents an unknown nucleotide, it is not possible to determine the corresponding RNA base for that position.
