Question

Визначте послідовність амінокислот якою починається білок якщо йому відповідає ділянка гена з такою послідовністю нуклеотидів: АЦГЦЦЦАТГГЦЦГГТ....щО ВІДБУДЕТЬСЯ ЯКЩО ПІД ВПЛИВОМ ОПРОМІНЕННЯ З МОЛЕКУЛИ ДНК буде вибито третій нуклеотид? Яким стане початок ланцюга амінокислот синтезованого білка?

Answer 1

Было: АЦГЦЦЦАТГГЦЦГГТ
Стало: ТГЦ ГГГ ТАЦ ЦГГ ЦЦА
Если выпадет 3 нуклеотид, то: 
ТГГГГТАЦЦГГЦЦА
Начало: ТГГ

Answer 2

Sequence of Amino Acids and the Impact of DNA Damage

The given DNA sequence is "АЦГЦЦЦАТГГЦЦГГТ" and we need to determine the sequence of amino acids that corresponds to this DNA sequence. Additionally, we need to understand the impact of DNA damage caused by the removal of the third nucleotide on the synthesis of the protein.

To determine the sequence of amino acids, we need to translate the DNA sequence into RNA and then into amino acids using the genetic code. 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.

The process of translation involves the following steps: 1. Transcription: The DNA sequence is transcribed into RNA. In this case, the DNA sequence "АЦГЦЦЦАТГГЦЦГГТ" will be transcribed into RNA as "УГЦГГГУАККЦЦГГА". 2. Translation: The RNA sequence is translated into amino acids using the genetic code.

To determine the sequence of amino acids, we can use an online tool or refer to the genetic code table. According to the genetic code, the RNA sequence "УГЦГГГУАККЦЦГГА" translates to the following sequence of amino acids: Serine-Glycine-Glycine-Tyrosine-Valine.

Now, let's consider the impact of DNA damage caused by the removal of the third nucleotide (Ц) on the synthesis of the protein. If the third nucleotide is removed, the RNA sequence will be "УГГГУАККЦЦГГА". As a result, the translation of this altered RNA sequence will lead to a different sequence of amino acids.

Using the same genetic code, the altered RNA sequence "УГГГУАККЦЦГГА" translates to the following sequence of amino acids: Serine-Glycine-Glycine-Lysine-Proline.

Therefore, if the third nucleotide is removed from the DNA sequence, the starting sequence of amino acids in the synthesized protein will change from Serine-Glycine-Glycine-Tyrosine-Valine to Serine-Glycine-Glycine-Lysine-Proline.

Please note that the provided information is based on the given DNA sequence and the standard genetic code. Different organisms may have variations in the genetic code, which can result in different translations of the same DNA sequence.
