Methionine is the amino acid associated with the AUG sequence on mRNA. The AUG sequence also indicates the beginning of a gene. Though the AUG sequence is necessary for gene expression, methionine is not necessary for all proteins. This is why it is usually removed after translation.
What else can I help you with?
What amino acid does every newly translated protein begin with?
In eukaryotes, every newly-translated protein begins with the amino acid methionine (Met, M). This is because the start codon that signals the beginning of translation is AUG, which is also the codon for methionine - so the correlation is obligatory. The methionine may be removed during post-translational processing/modification.In prokaryotes, however, every newly-translated protein begins with formylmethionine (fMet), a methionine derivative with a formyl group added to the amino group. This difference can be used as a target for antibiotic therapy. As with methionine, the formylmethionine can be removed after translation.
What is the first amino acids in most proteins?
Methionine. It functions as the "start" codon (tells the translation apparatus to start translating) and as a result is usually the first amino acid. However, it is frequently removed later. Methionine is by far the most common amino acid to find at the beginning of a chain, and will almost always have been there at some stage during protein synthesis. There is no other amino acid you can confidently claim is the first amino acid in anything but a small proportion of proteins.
A sequence of mRNA that is expressed after processing?
The processed mRNA sequence that is ready for translation is called mature mRNA. It has had introns removed and exons spliced together during post-transcriptional processing. This mature mRNA is then exported from the nucleus to the cytoplasm for translation into protein.
What does failure to remove introns from a primary mRNA most likely cause?
Failure to remove introns from a primary mRNA during mRNA processing will likely result in the production of a non-functional or defective protein. This is because introns are non-coding sequences that need to be removed to produce a mature and functional mRNA for translation. If the introns are not removed, the resulting mRNA will contain incorrect coding information, leading to errors in the protein synthesis process.
The sections of an mRNA molecule that are removed before translation are?
The sections of an mRNA molecule that are removed before translation are called introns. This process is known as splicing, where introns are removed and the remaining sections, called exons, are joined together to form the mature mRNA molecule. This ensures that only the coding regions of the gene are included in the final mRNA sequence for translation.
What is the starting amino acid for the beta globin protein?
Methionine. Protein translation starts at the start codon (AUG) which also codes for methionine. It means all proteins start with methionine at their N-terminus, although it's usually removed by post-translational modification.

What are the basic steps of protein synthesis?
Initiation: ribosome starts translation at start codon (AUG) Elongation: amino acid chain gets longer and longer as tRNA bring corresponding amino acids Termination: ribosome ends translation at stop codon or termination sequence (UAG, UGA, UAA) Post-translational Modification: protein splicing occurs (intein excission for final protein functionality); N-terminal and C-terminal modification (removed in prokaryotes and acetylated in eukaryotes); chemical modification (phosphorylation/dephosphorylation or glycosylation); protein folding
In most organisms the start of translation is signaled by an AUG codon. What is the first amino acid in most proteins?
In most organisms, the first amino acid in proteins is methionine, which is encoded by the AUG codon. Methionine serves as the initiation signal for translation, although it can be removed post-translationally in some proteins. In prokaryotes, a modified form called N-formylmethionine (fMet) is often used at the start of protein synthesis.

Can a co-borrower be removed with a loan modification?
If the lender agrees to it.
What's the usage of D-Methionine?
methionine is an essential amino acid meaning if it is entirely removed from animal diets disease and death will occur over time.methionine is can be used as supplement to organic poultry feedDL-Methionine may be given to dogs to reduce the pH of dog urine in order to protect plants/grass
What substance derived from protein is removed from the blood in the kidneys and excreted in urine?
Urea is the substance derived from protein metabolism that is removed from the blood in the kidneys and excreted in urine.
