What else can I help you with?
Is ATG a start codon in genetic coding?
No, ATG is not a start codon in genetic coding. The start codon is typically AUG.
Is "AUG" a start codon in genetic coding?
Yes, "AUG" is a start codon in genetic coding.
Is AUG the start codon in genetic translation?
Yes, AUG is the start codon in genetic translation.
Is "aug" a stop codon in genetic code?
No, "aug" is not a stop codon in the genetic code. It is actually the start codon that signals the beginning of protein synthesis.
Is AUG always the start codon in genetic sequences?
No, AUG is not always the start codon in genetic sequences. While it is the most common start codon, there are other start codons such as GUG and UUG that can initiate protein synthesis in certain organisms.

Why is AUG the start codon in genetic translation?
The AUG codon serves as the start codon in genetic translation because it codes for the amino acid methionine, which is essential for initiating protein synthesis. This codon signals the ribosome to begin translating the mRNA sequence into a protein.
Why every gene need a start codon?
A start codon acts as the signal for the beginning of a protein-coding sequence in a gene. It helps to initiate the process of translation, where the genetic information is used to synthesize a protein. Without a start codon, the translation machinery would not know where to begin and the protein synthesis process would not proceed properly.
What are the structures of Genes?
The Fine Structures are as follows: 1) The Start Codon: Met is specific for one amino acid [Met] yet f-Met uniquely specifies the Start codon.2) There are two kinds of 'upstream promotion' sequences: i) the furthest upstream are called the 'Enhancer sequences', and ii) the control sequences nearer to the Gene are called the 'Promoter sequences'.3) Right beside the Promoter sequence is always found the Operator Sequence: this proffers the attachment for and to the Start Codon. After the Start Codon, the Protein Coding Sequence ensues, followed by Termination sequences.
What is in DNA a three nucleotide sequence that encodes an amino acid or signifies a start signal or a stop signal?
A three-nucleotide sequence in DNA that encodes an amino acid is called a codon. There are also specific codons that signal the start of protein synthesis (start codon) or the termination of protein synthesis (stop codon). These codons help in translating the genetic code from DNA to proteins during transcription and translation processes.
What is the DNA sequence that represents the start codon?
The start codon is represented by the DNA sequence "ATG," which corresponds to the mRNA codon "AUG." This sequence signals the beginning of protein synthesis and codes for the amino acid methionine. In the genetic code, the presence of this start codon is essential for initiating translation in both prokaryotic and eukaryotic organisms.
Do all polypeptides begin with amino acid coded for by the start codon?
Yes, all polypeptides begin with an amino acid specified by the start codon, which is typically AUG, coding for methionine in eukaryotes. This start codon signals the ribosome to initiate translation and sets the reading frame for the subsequent codons. In some cases, the initial methionine may be removed post-translationally, but the translation process always begins with the start codon.
What is the significance of the mRNA start codon in initiating protein synthesis?
The mRNA start codon, usually AUG, plays a crucial role in initiating protein synthesis. It signals the ribosome to start translating the mRNA sequence into a protein. This codon marks the beginning of the protein coding sequence and helps establish the correct reading frame for translation.
