What else can I help you with?
Where does the small sub unit of rna join to mrna?
The small subunit of ribosomal RNA (rRNA) joins to mRNA at the ribosome, specifically at the start codon of the mRNA transcript. This interaction occurs during the initiation phase of translation, where the small ribosomal subunit recognizes the mRNA's 5' cap and the start codon (AUG), facilitating the assembly of the ribosome for protein synthesis.
Where must An MRNA Attach Before Protein Can Begin?
The ribosome.
What Moves along the mRNA and helps form the peptide strand?
Ribosomes move along the mRNA during protein synthesis. They help bring together amino acids to form a peptide strand based on the nucleotide sequence of the mRNA.
Which best summarizes the process of protein synthesis?
.........................This is what it is americans.................. 1. an mRNA molecule binds to the small ribosomal subunit at the mRNA biding site. A special tRNA, called initiator tRNA, binds to the start codon (AUG) on mRNA, where translation begins. The tRNA anticodon (UAC) attaches to the mRNA codon (AUG) by pairing between the complementary bases. Besides being the start codon, AUG is also the codon for the amino acid methionine. Thus, methionine is always the first amino acid in a growing polypeptide2. Next, the large ribosomal subunit attaches to the small ribosomal subunit-mRNA complex, creating a functional ribosome. The initiator tRNA, with its amino acid (methionine), fits into the P site of the ribosome.3. The anticodon of another tRNA with its attached amino acid pairs with the second mRNA codon at the A site of the ribosome.4. A component of the large ribosomal subunit catalyzes the formation of a peptide bond between methionine, which separates from its tRNA at the P site, and the amino acid carried by the tRNA at the A site.5. After peptide bond formation, the empty tRNA at the P site detaches from the ribosome, and the ribosome shifts the mRNA strand by one codon. The tRNA in the A site bearing the two-peptide protein shifts into the P site, allowing another tRNA with its amino acid to bind to a newly exposed codon at the A site. Steps 3 through 5 occur repeatedly, and the protein lengthens progressively.6. Protein synthesis ends when the ribosome reaches a stop codon at the A site, which causes the completed protein to detach from the final tRNA. When the tRNA vacates the A site, the ribosome splits into its large and small subunits.Read more: List_the_sequence_of_events_that_happens_during_protein_synthesis
Is Initiation the second step in translation?
No, Initiation is the first step in translation. It involves the binding of mRNA to the small subunit of the ribosome, which marks the beginning of the translation process.
Translation begins when the initiator tRNA binds to the?
start codon on the mRNA strand. This signals the ribosome to begin assembling the amino acid sequence based on the mRNA instructions.
What is the result of Transcription?
DNA is converted to a strand of mRNA to be translated in the ribosome.
Observe how the mRNA interacts with the ribosome in the simulation. How is this interaction different than what actually happens in translation?

What is a ribosome and what does it do?
A ribosome is a two subunit complex made of protein and catalytic RNA that unites as one unit when mRNA docks on the large subunit. Ribosomes are the " workbench " on which proteins are synthesized. The ribosome crawls along the mRNA and knits together a polypeptide chain from the free amino acids brought to the ribosome by tRNA.
Where does the small sub unit of rna join to mrna?
The small subunit of ribosomal RNA (rRNA) joins to mRNA at the ribosome, specifically at the start codon of the mRNA transcript. This interaction occurs during the initiation phase of translation, where the small ribosomal subunit recognizes the mRNA's 5' cap and the start codon (AUG), facilitating the assembly of the ribosome for protein synthesis.
What is the relationship between the template strand and the mRNA transcribed from it?
The template strand is used as a guide to create mRNA during transcription. The mRNA is complementary to the template strand and carries the genetic information from the DNA to the ribosome for protein synthesis.
Which is the first event in translation in eukaryotes?
ANSWER: the small subunit of the ribosome recognizes and attaches to the 5' cap of mRNA ------------------------------------------------------------------------------------------------------- This answer bellow, appears all over the internet, but its wrong. I just took a quiz. -base pairing of activated methionine-tRNA to AUG of the messenger.
Where does the process of translation do in mRNA?
The newly spliced mRNA binds to a ribosome. tRNA molecules migrate towards the ribosome, these tRNA molecules carries a specific amino acid. The ribosome allows two tRNA molecules into the ribosome at a time. The tRNA molecules have complementary anti-codons to the codons present on the mRNA strand. Two tRNA move into the ribosome and their anti-codons join to complementary codons on the mRNA strand. As one molecule leaves the ribosome, its amino acid forms a peptide bond with an amino acid on the adjacent tRNA molecule, with the help of ATP and an enzyme. As the ribosome moves along the the mRNA strand, a polypeptide chain is created. The ribosome stops reading the mRNA strand when it reaches a stop codon.
Where is protein made?
Proteins are made in the ribosomes when the mRNA strand from the nucleus is matched with the anti codon tRNA strand.
How do you make a protein from DNA?
mRNA transcribes a strand of DNA and carries the genetic code to a ribosome, where the mRNA code is translated by tRNA into a strand of amino acids, making a protein.
How does a ribosomes?
The ribosome is worked with a combination of the three RNAs, the tRNA to supply the anticodons and the amino acids, mRNA to supply the codons and the informations, and ribosome, which is about 60% rRNA and 40% proteins and comes in two subunits, one large and one small. When the mRNA is sent out into the cytoplasm, a message is sent to assemble the two subunits which have previously been separated. The mRNA attaches to the small subunit, then the tRNA attaches itself to the mRNA. Finally, the large subunit of the ribosome attaches itself and the translation begins.
Where must An MRNA Attach Before Protein Can Begin?
The ribosome.
