What else can I help you with?
Where must An MRNA Attach Before Protein Can Begin?
The ribosome.
When does the polypeptide stop growing?
The polypeptide stops growing when it reaches a stop codon on the mRNA during translation. This signals the ribosome to release the polypeptide chain, which then undergoes further processing to become a functional protein.
How does the cell make the first ribosom?
The first ribosome is formed through a process called ribosome biogenesis, which occurs in the nucleolus of the cell. Ribosomal RNA (rRNA) is synthesized from ribosomal DNA (rDNA) and combined with ribosomal proteins imported from the cytoplasm. This assembly creates the small and large subunits of the ribosome, which are then transported to the cytoplasm where they combine to form a functional ribosome, essential for protein synthesis.
How does mrna interact with the ribosome?
mRNA interacts with the ribosome by binding to its ribosomal RNA (rRNA) components, allowing the ribosome to read the mRNA sequence. The ribosome scans the mRNA from the 5' end to the 3' end, identifying codons, which are sequences of three nucleotides that correspond to specific amino acids. Transfer RNA (tRNA) molecules bring the appropriate amino acids to the ribosome based on these codons, facilitating protein synthesis through a process called translation. This interaction is crucial for translating the genetic code into functional proteins.
What manufactures ribosome parts ( proteins and RNA)?
Ribosome parts, consisting of ribosomal RNA (rRNA) and ribosomal proteins, are primarily manufactured in the nucleolus of eukaryotic cells. In prokaryotic cells, ribosome assembly occurs in the cytoplasm. The nucleolus synthesizes rRNA, which combines with proteins imported from the cytoplasm to form ribosomal subunits. These subunits are then transported to the cytoplasm, where they assemble into functional ribosomes.
What is a functional characteristics of ribosome?
DNA replication
What happens at the end of translation?
the amino acids detach from the ribosome
What happens at the end of translation in the p site?
the amino acids detach from the ribosome
What is required to produce proteins from amino acids?
An mRNA transcript carries the genetic code to the ribosome. tRNA molecules bring amino acids to the ribosome for translation. The amino acids polymerize into functional proteins.
Where must An MRNA Attach Before Protein Can Begin?
The ribosome.
What manufactures ribosome parts in a cell?
In a cell, ribosome parts are manufactured in the nucleolus, a substructure located within the cell's nucleus. The nucleolus is responsible for assembling the ribosomal RNA and combining it with proteins to form the ribosomal subunits, which are then exported to the cytoplasm for final assembly into functional ribosomes.
When does the polypeptide stop growing?
The polypeptide stops growing when it reaches a stop codon on the mRNA during translation. This signals the ribosome to release the polypeptide chain, which then undergoes further processing to become a functional protein.

Where did the Internet first become functional?
The internet became functional in 1982
What makes enzymes?
Enzymes are folded proteins. Proteins are made by ribosomes in the cell. To be specific, information in the nucleus (DNA) is transcripted to mRNA which leaves the nucleus to go to a ribosome to help it assemble amino acids (which are the building blocks of protein). The ribosome "reads" the information of the mRNA and make a sequence of amino acids based on that. This chain of amino acids will become folded due to interactions between between each amino acids which will ultimately become a fully functional protein. This protein may become an enzyme. All enzymes are proteins but not all proteins are enzymes.
