Question

Ділянка базового ланцюга молекули ДНК має таку структуру:-Г-Г-Т-А-Ц-Г-А-Ц-А-ГВизначте структуру відповідної ділянки лівого ланцюга молекули ДНК. Яка довжина цієї ділянки молекули ДНК? Яка структура і-РНК, Синтезованої на матриці правого ланцюга молекули ДНК?

Answer 1

Ц-Ц-А-Т-Г-Ц-Т-Г-Т-Ц -днк
довжина = 0,34 нм *10 =3,4 нм
Ц-Ц-А-У-Г-Ц-У-Г-У-Г - рнк

Answer 2

Structure of the Left Strand of DNA Molecule

The given sequence of the right strand of the DNA molecule is "Г-Г-Т-А-Ц-Г-А-Ц-А-Г". To determine the structure of the left strand, we need to identify the complementary bases for each nucleotide in the right strand.

In DNA, the bases always pair up in a specific way: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, the complementary bases for the given sequence are as follows:

- Г pairs with Ц - Ц pairs with Г - А pairs with Т - Т pairs with А - Г pairs with Ц - А pairs with Т - Ц pairs with Г - А pairs with Т - Г pairs with Ц

Therefore, the structure of the left strand of the DNA molecule corresponding to the given sequence is "Ц-Ц-А-Т-Г-Ц-Т-Г-Т-Ц".

Length of the DNA Molecule Segment

To determine the length of the DNA molecule segment, we need to count the number of nucleotides in the given sequence. The sequence "Г-Г-Т-А-Ц-Г-А-Ц-А-Г" contains 10 nucleotides. Therefore, the length of this DNA molecule segment is 10 nucleotides.

Structure of the RNA Synthesized on the Template of the Right Strand

When RNA is synthesized on the template of the right strand of the DNA molecule, the complementary bases are used. However, in RNA, thymine (T) is replaced by uracil (U). Therefore, the structure of the RNA synthesized on the template of the right strand of the DNA molecule would be as follows:

- А (from the right strand) pairs with У (in the synthesized RNA) - Т (from the right strand) pairs with А (in the synthesized RNA) - Ц (from the right strand) pairs with Г (in the synthesized RNA) - Г (from the right strand) pairs with Ц (in the synthesized RNA) - А (from the right strand) pairs with У (in the synthesized RNA) - Ц (from the right strand) pairs with Г (in the synthesized RNA) - Г (from the right strand) pairs with Ц (in the synthesized RNA) - А (from the right strand) pairs with У (in the synthesized RNA) - Ц (from the right strand) pairs with Г (in the synthesized RNA) - А (from the right strand) pairs with У (in the synthesized RNA)

Therefore, the structure of the RNA synthesized on the template of the right strand of the DNA molecule would be "У-А-Г-Ц-У-Г-Ц-У-Г-У".
