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.
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.
Is mRNA used to carry the genetic code from DNA to ribosomes?
mRNA carries the genetic code to a ribosome.
What is the difference between the Kozak sequence and the Shine-Dalgarno sequence in terms of their roles in translation initiation?
The Kozak sequence is found in eukaryotic mRNA and helps the ribosome to identify the start codon for translation initiation. The Shine-Dalgarno sequence is found in prokaryotic mRNA and helps the ribosome to bind to the mRNA and start translation. Both sequences play important roles in translation initiation, but they are specific to different types of organisms.
Observe how the mRNA interacts with the ribosome in the simulation. How is this interaction similar to what actually happens in translation?
The interaction between mRNA and ribosomes in the simulation is meant to reflect the process of translation that occurs in cells. During translation, the ribosome uses the information stored in the mRNA molecule to synthesize a protein. The ribosome moves along the mRNA molecule and reads its codons (sets of three nucleotides) to determine which amino acids should be added to the growing polypeptide chain. In the simulation, the mRNA molecule is represented as a linear sequence of codons, and the ribosome is represented as a moving object that recognizes and interacts with the codons. The ribosome moves along the mRNA and recognizes each codon by binding to it. This interaction is similar to what happens in real cells, where the ribosome recognizes codons by binding to specific sites on the mRNA molecule. In the simulation, the ribosome can also interact with tRNA molecules, which bring the correct amino acids to the ribosome for incorporation into the growing polypeptide chain. This is similar to what happens in real cells, where tRNA molecules bring the correct amino acids to the ribosome for use in protein synthesis. Overall, the interaction between mRNA and ribosomes in the simulation is meant to closely resemble the process of translation that occurs in cells.
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.
What molecule is used to take this DNA code out to the ribosome?
mRNA (messenger RNA) is the molecule that carries the copied code from the DNA in the nucleus to the ribosome.
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.
Which RNA molecules are involvedin the synthesis or a protein?
mRNA, rRNA, tRNA mRNA transcribes the genetic code and carries it to a ribosome, which is composed of rRNA and proteins, and tRNA carries amino acids to the ribosome where the amino acids are assembled in the correct sequence according to the mRNA code.
What is the correct order for activation elongation initiation termination?
The correct order of processes in protein synthesis is initiation, elongation, and termination. During initiation, the ribosome assembles around the mRNA and the first tRNA binds to the start codon. Elongation follows, where amino acids are added to the growing polypeptide chain as the ribosome moves along the mRNA. Finally, termination occurs when a stop codon is reached, prompting the release of the completed protein.
What carries a copy the genetic code from the DNA to the ribosome?
mRNA(messenger RNA)
What happens when the ribosome reads the codon uga?
When the ribosome encounters the codon UGA during translation, it recognizes it as a stop codon. This signals the termination of protein synthesis, leading to the release of the newly synthesized polypeptide chain from the ribosome. Release factors bind to the ribosome, facilitating the disassembly of the ribosomal complex and the release of the mRNA. As a result, translation ends, and the ribosome is free to initiate translation of another mRNA.
