They all begin with AUG, which is the start codon.

Every mRNA must begin with the start codon AUG, which codes for the amino acid methionine. This start codon marks the site where translation should begin on the mRNA molecule.

What is the protein strand created from the mrna strand cagaaguuccucucgc?
The mRNA sequence cagaaguuccucucgc would be translated into the protein sequence Glutamine-Lysine-Serine-Leucine-Arginine. Each set of three nucleotides (codon) in the mRNA corresponds to a specific amino acid in the protein sequence during translation.
Why do all polypeptide chains start with methionine?
In eukaryotic cells, the start codon for protein synthesis is always AUG, which codes for methionine. Methionine is the initiator amino acid that signals the ribosome to start translation. Additionally, methionine helps stabilize the structure of the nascent polypeptide chain during synthesis.
Why do cells have to produce RNA from DNA?
Cells must produce RNA from DNA in order to carry out essential cellular functions such as protein synthesis. RNA serves as a messenger molecule that carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm where proteins are made. This process is crucial for the proper functioning and regulation of cellular processes.
MRNA must pass through which membrane?
The nuclear membrane.In eukaryotic cells, DNA is transcribed into mRNA within the nucleus. Once transcription is complete the mRNA must exit the nucleus to be translated into protein, which ocurrs in the cytoplasm. Thus, mRNA must pass through the nuclear membrane.
Where must An MRNA Attach Before Protein Can Begin?
The ribosome.
If an mRNA is made up of 60 bases how many codons does it contain and how many amino acid does it code for?
A codon is exactly three bases long, so an mRNA strand with 60 bases would contain 20 codons. The first codon will encode for methionine (this is called the "start" codon) and the last codon will be a "stop" codon, which does not encode for an amino acid. Thus, an mRNA strand of 60 bases will code for 19 amino acids. Keep in mind, it is possible for a stop codon to be anywhere on the mRNA strand, and when a stop codon reaches the ribosome, translation must stop. For example, if an mRNA strand contained 30 codons, and the 15th were a stop codon, the mRNA would only code for 14 amino acids and then be done. The other 15 codons would go untranslated.
In tRNA why does the agc anticodon need to pair with a specific mRNA codon and what is the mRNA codon it pairs with?
The tRNA anticodon must pair with a specific mRNA codon to ensure accurate translation of genetic information during protein synthesis. The anticodon AGC pairs with the mRNA codon UCG, which codes for the amino acid serine. This specific pairing allows for the correct amino acid to be added to the growing polypeptide chain.
Briefly describe how the process of translation is started?
In the cytoplasm, rRNA binds to the "start" codon of a mRNA molecule. Next, a tRNA molecule with the complimentary anticodon binds to the mRNA start codon and releases an amino acid. As the mRNA moves through the rRNA, new tRNA's come along and bind to the mRNA, adding a new amino acid each time. Eventually a "stop" codon is reached, and the rRNA, mRNA, and tRNA break apart, releasing a long chain of amino acids which will fold into a protein.

The mRNA sequence cagaaguuccucucgc would be translated into the protein sequence Glutamine-Lysine-Serine-Leucine-Arginine. Each set of three nucleotides (codon) in the mRNA corresponds to a specific amino acid in the protein sequence during translation.
Where does the lining up of a codon and an anticodon take place?
The lining up of a codon (on mRNA) and anticodon (on tRNA) takes place at the ribosome during translation. The ribosome acts as the site where the mRNA is read and the corresponding amino acids are brought in by tRNA molecules, which have complementary anticodons to the codons on mRNA.
What is the amino sequence of the protein that was formed?
In order to answer this question, you must, and prpbably do have the codon sequences of the RNA or DNA, and a chart saying what each codon codes for in terms of amino acids. The mRNA from transcription is what the sheet probably has on it, with each codon contained therin signaling a certain amino acid. If you can post the sequence or something like that, then ill sertainly answer it for you.
In order for protein synthesis to occur mRNA must migrate to the?
ribosome, where it serves as a template for the assembly of amino acids into a protein chain. This process is facilitated by transfer RNA (tRNA) molecules that bring the appropriate amino acids to the ribosome based on the codons on the mRNA. Once the ribosome reaches a stop codon on the mRNA, protein synthesis is complete.
Why do all polypeptide chains start with methionine?
In eukaryotic cells, the start codon for protein synthesis is always AUG, which codes for methionine. Methionine is the initiator amino acid that signals the ribosome to start translation. Additionally, methionine helps stabilize the structure of the nascent polypeptide chain during synthesis.

Protein synthesis steps?
The major steps of protein synthesis are:1. Transcription-before a protein can be synthesized, the DNA information or code must first be copied or transcribed to a type of RNA called mRNA (messenger RNA). Bothe the codes in DNA and mRNA are carried as units called codons.2. Translation-in the ribosome, the code carried by the mRNA is translated into a sequence of amino acids that will form the protein molecule dictated by the DNA.
