Answer 1

Ответ:

Нетранскрибируемая цепь ДНК(вторая): ЦТТГЦГАААТТЦ

иРНК: ЦУУГЦГАААУУЦ

Объяснение: Согласно принципу комплементарности

А=Т(У)

Г=Ц

Answer 2

Nucleotide Sequence in mRNA and Non-Transcribed DNA Strand

The given nucleotide sequence in the transcribed DNA strand is "GAACGCTTTAAG". To determine the nucleotide sequence in the mRNA and the non-transcribed DNA strand, we need to understand the process of transcription and the complementary base pairing rules.

During transcription, the DNA sequence is used as a template to synthesize a complementary mRNA molecule. The mRNA is synthesized in the 5' to 3' direction, and the nucleotides are added to the growing mRNA chain based on the complementary base pairing rules: adenine (A) pairs with uracil (U), cytosine (C) pairs with guanine (G), guanine (G) pairs with cytosine (C), and thymine (T) pairs with adenine (A).

To determine the nucleotide sequence in the mRNA, we can simply replace the thymine (T) nucleotides in the transcribed DNA strand with uracil (U). Therefore, the nucleotide sequence in the mRNA would be "GAACGCUUUAAG".

To determine the nucleotide sequence in the non-transcribed DNA strand, we need to find the complementary base pairs for each nucleotide in the transcribed DNA strand. The complementary base pairing rules state that adenine (A) pairs with thymine (T), cytosine (C) pairs with guanine (G), guanine (G) pairs with cytosine (C), and thymine (T) pairs with adenine (A).

Therefore, the nucleotide sequence in the non-transcribed DNA strand would be the complementary sequence of the transcribed DNA strand. In this case, the complementary sequence would be "CTTGCGAAATTC".

To summarize: - Nucleotide sequence in the mRNA: GAACGCUUUAAG - Nucleotide sequence in the non-transcribed DNA strand: CTTGCGAAATTC

Please note that the provided answer is based on the given information and the understanding of transcription and complementary base pairing rules.
