Question

Днк содержит такую последовательность нуклеотидов в АЦЦ ТГТ А,АЦ ААЦ.определите последовательность аминокислот,закодированных

Answer 1

Для того, чтобы определить состав белка, нужно знать нуклеотидную цепочку иРНК по принципу комплементраности.
иРНК: УГГ АЦА УУГ УУГ
аминокислоты: триптофан, треонин, лейцин, лейцин

Answer 2

DNA Sequence and Amino Acid Coding

The given DNA sequence is "АЦЦ ТГТ А,АЦ ААЦ". To determine the sequence of amino acids encoded by this DNA sequence, we need to first translate the DNA sequence into RNA and then use the genetic code to convert the RNA sequence into amino acids.

1. Transcription: DNA is transcribed into RNA. In this process, the DNA sequence is converted into its complementary RNA sequence. The DNA bases are replaced as follows: - Adenine (A) in DNA is replaced by Uracil (U) in RNA. - Thymine (T) in DNA is replaced by Adenine (A) in RNA. - Cytosine (C) in DNA is replaced by Guanine (G) in RNA. - Guanine (G) in DNA is replaced by Cytosine (C) in RNA.

Therefore, the transcribed RNA sequence from the given DNA sequence "АЦЦ ТГТ А,АЦ ААЦ" would be "УГГ АКА У,УГ УУГ".

2. Translation: The RNA sequence is then translated into amino acids using the genetic code. The genetic code is a set of rules that determines how the sequence of nucleotides in RNA is converted into the sequence of amino acids in a protein.

The genetic code is read in groups of three nucleotides called codons. Each codon corresponds to a specific amino acid or a stop signal. Here is an example of the genetic code:

| Codon | Amino Acid | |-------|------------| | УУУ | Phenylalanine (Phe) | | УУЦ | Phenylalanine (Phe) | | УУА | Leucine (Leu) | | УУГ | Leucine (Leu) | | УЦУ | Serine (Ser) | | УЦЦ | Serine (Ser) | | УЦА | Serine (Ser) | | УЦГ | Serine (Ser) | | УАУ | Tyrosine (Tyr) | | УАЦ | Tyrosine (Tyr) | | УАА | Stop | | УАГ | Stop | | УГУ | Cysteine (Cys) | | УГЦ | Cysteine (Cys) | | УГА | Stop | | УГГ | Tryptophan (Trp) | | УСУ | Serine (Ser) | | УСЦ | Serine (Ser) | | УСА | Serine (Ser) | | УСГ | Serine (Ser) | | УГА | Stop | | УГГ | Tryptophan (Trp) |

Using the genetic code, we can determine the sequence of amino acids encoded by the given RNA sequence "УГГ АКА У,УГ УУГ". The amino acid sequence would be "Leucine-Cysteine-Leucine, Serine-Tryptophan".

Please note that the provided DNA sequence and its corresponding amino acid sequence are based on the information available. For a more accurate analysis, it is recommended to consult a geneticist or use specialized software for DNA sequence analysis.
