Question

Визначте послідовність нуклеотидів іншого ланцюга ДНК, якщо преший фрагмент має такий склад: АЦТ-ТТГ-ГАТ-ТТТ-ГТА-АЦТ-ГТГ По возможности: За допомогою таблиці генетичного коду визначте амінокислотний склад поліпептидного ланцюга синтезованого на фрагменті ДНК: ТАА-ТАА-ЦТА-ААА-ТГА-ЦАЦ

Answer 1

Ответ:

Другий ланцюг:

ТГА-ААЦ-ЦАА-ААА-ЦАТ-ТГА-ЦАЦ

Объяснение:

За правилом Чаргаффа: А=Т; Г=Ц

А - аденін Т - тимін Ц - цитозин Г - гуанін

Answer 2

Sequence of Nucleotides in the Other DNA Strand:

To determine the sequence of nucleotides in the other DNA strand, we need to understand the complementary base pairing rules in DNA. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, the complementary sequence to the given DNA fragment "АЦТ-ТТГ-ГАТ-ТТТ-ГТА-АЦТ-ГТГ" would be:

TGA-AAC-CTA-AAA-CAT-TGA-TGA-CAC

This is because A pairs with T, C pairs with G, and the sequence is read in the opposite direction.

Amino Acid Sequence Synthesized from the DNA Fragment:

To determine the amino acid sequence synthesized from the given DNA fragment "ТАА-ТАА-ЦТА-ААА-ТГА-ЦАЦ," we need to use the genetic code table. The genetic code is a set of rules that determines how the sequence of nucleotides in DNA or RNA is translated into the sequence of amino acids in a protein.

Using the genetic code table, we can translate each codon (a sequence of three nucleotides) into the corresponding amino acid. Here is the translation of the given DNA fragment:

ТАА-ТАА-ЦТА-ААА-ТГА-ЦАЦ

The corresponding amino acids for each codon are as follows:

ТАА: Stop codon ТАА: Stop codon ЦТА: Leucine (Leu) ААА: Lysine (Lys) ТГА: Stop codon ЦАЦ: Histidine (His)

Therefore, the amino acid sequence synthesized from the given DNA fragment is:

Leu-Lys-His

Please note that the translation of the genetic code is based on the standard genetic code. There are some variations in the genetic code in different organisms, but the standard genetic code is widely used as a reference.
