Question

Фрагмент цепи ДНК имеет следующую последовательность: ГГАТЦТАААЦАТ. Определите последовательность нуклеотидов на второй цепи ДНК, иРНК. Определите последовательность аминокислот во фрагменте молекулы белка, используя таблицу генетического кода.

Answer 1

ГГА-ТЦТ-ААА-ЦАТ

ЦЦТ-АГА-ТТТ-ГТА вторая цепочка ДНК

ГГУ-УЦУ-ААА-ЦАУ -РНК

глицин-серин-лизин-гистидин-названия

Answer 2

DNA Sequence:

The given DNA sequence fragment is "ГГАТЦТАААЦАТ". To determine the sequence of nucleotides on the second DNA strand, we need to identify the complementary base pairs. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, the complementary sequence on the second DNA strand would be "CCTAGAATTTGTAT".

RNA Sequence:

To determine the RNA sequence, we need to replace thymine (T) with uracil (U) since RNA does not contain thymine. Therefore, the RNA sequence corresponding to the given DNA fragment would be "CCUAGAAUUUGUAU".

Amino Acid Sequence:

To determine the amino acid sequence in the protein molecule fragment, we need to use the genetic code table. Each three-nucleotide sequence, called a codon, corresponds to a specific amino acid. Here is the translation of the RNA sequence into amino acids using the genetic code table:

- CCU: Proline (Pro) - AGA: Arginine (Arg) - AUU: Isoleucine (Ile) - UUG: Leucine (Leu) - UAU: Tyrosine (Tyr)

Therefore, the amino acid sequence in the protein fragment would be Pro-Arg-Ile-Leu-Tyr
