A. DNA has the genetic sequences in the right order to make the proteins. It shows what order the amino acids have to be in to make a protein. B. mRNA is the messenger; hence m for messenger RNA. It takes a copy of the genetic sequence from the DNA and leaves the nucleus of the cell and goes to the ribosome for translation. C. tRNA is responsible for transferring the amino acids in the cytoplasm to the ribosome. Once it drops off the amino acid in the ribosome, it leaves and attaches to another for the same process. D. Amino acids are the building blocks of all living organisms. A sequence of them and put them together to form a poly-peptide.
- Transcription: the process of creating an mRNA copy of a gene's DNA sequence.
- Translation: the process of using the mRNA code to assemble amino acids into a protein at the ribosome.
- Ribosome: the cellular machinery where translation occurs, with tRNA molecules bringing specific amino acids to the ribosome based on the mRNA sequence.

What molecule caries an amino acid to the site of protein synthesis?
Transfer RNA (tRNA) carries an amino acid to the site of protein synthesis on the ribosome. Each tRNA molecule has a specific amino acid attached to it and matches with the corresponding codon on the messenger RNA (mRNA) during protein synthesis.
How does amino acids get to the site of protein synthesis?
Amino acids are brought to the site of protein synthesis by transfer RNA (tRNA) molecules. Each tRNA molecule is specific to a particular amino acid and carries it to the ribosome, where protein synthesis occurs. The tRNA molecules recognize the codons on the mRNA and deliver the corresponding amino acids to the growing protein chain.
During protein synthesis messenger RNA what?
Messenger RNA molecules are fed through the ribosomes during protein synthesis.
How many steps are there in protein synthesis?
Protein synthesis involves two main steps: transcription, where the information in DNA is copied into messenger RNA (mRNA) in the nucleus; and translation, where the mRNA is used as a template to assemble amino acids into a protein at ribosomes in the cytoplasm. Each step consists of multiple sub-steps involving different molecules and enzymes.
What are the functions of each type of the RNA?
mRNA carries genetic information from DNA to the ribosome for protein synthesis. tRNA brings amino acids to the ribosome during protein synthesis. rRNA makes up the ribosome and is involved in protein synthesis. PTEN RNA regulates gene expression and cell growth. miRNA regulates gene expression by binding to target mRNAs. snoRNA guides chemical modifications of other RNAs.
Inhibitor of protein synthesis?
An inhibitor of protein synthesis is a substance that interferes with the process of creating new proteins within a cell. This disruption can occur at various stages of protein synthesis, leading to a decrease in protein production. Examples of protein synthesis inhibitors include antibiotics like tetracycline and erythromycin, which target bacterial ribosomes and block protein translation.
What molecule caries an amino acid to the site of protein synthesis?
Transfer RNA (tRNA) carries an amino acid to the site of protein synthesis on the ribosome. Each tRNA molecule has a specific amino acid attached to it and matches with the corresponding codon on the messenger RNA (mRNA) during protein synthesis.
What are the best nucleotide triplets that best represent a codon?
The best nucleotide triplets that represent a codon are Adenosine, Cytosine, Guanine, and Uracil (A, C, G, and U). These nucleotides form RNA molecules, which are used during protein synthesis to encode the sequence of amino acids in a protein. Each triplet of nucleotides, or codon, corresponds to a specific amino acid or a signal to start or stop protein synthesis.
How does amino acids get to the site of protein synthesis?
Amino acids are brought to the site of protein synthesis by transfer RNA (tRNA) molecules. Each tRNA molecule is specific to a particular amino acid and carries it to the ribosome, where protein synthesis occurs. The tRNA molecules recognize the codons on the mRNA and deliver the corresponding amino acids to the growing protein chain.

Each step consists of multiple sub-steps involving different molecules and enzymes.
What molecules contain the codons?
Codons are found in mRNA molecules, which are transcribed from DNA molecules during protein synthesis. Each codon corresponds to a specific amino acid or a signal for the start or end of protein synthesis.
What are the functions of each type of the RNA?
mRNA carries genetic information from DNA to the ribosome for protein synthesis. tRNA brings amino acids to the ribosome during protein synthesis. rRNA makes up the ribosome and is involved in protein synthesis. PTEN RNA regulates gene expression and cell growth. miRNA regulates gene expression by binding to target mRNAs. snoRNA guides chemical modifications of other RNAs.
How do the vacuole and the ribosomes interact with each other in a cell?
Ribosomes synthesize proteins within a cell, which are then transported to the vacuole for storage or cellular processes. The vacuole can also contain ribosomes, allowing for localized protein synthesis. Overall, the vacuole and ribosomes work together to maintain cellular function by regulating protein synthesis and storage.
Why must protein synthesis be accurate?
Because each amino acid put into the growing polypeptide chain that will become a protein has an R group with different binding characteristics that can change the shape of the protein, thus the action of the protein, if not accurately placed for that particular protein in it's tertiary form.
Is there a specific type of mRNA for each amino acid?
Messenger RNA, transfer RNA, and ribosomal RNA play a role in protein synthesis.
What carries an amino acid from the cytoplasm to a ribosome?
Transfer RNA (tRNA) carries an amino acid from the cytoplasm to a ribosome during protein synthesis. Each tRNA molecule recognizes a specific codon on the mRNA and pairs it with the corresponding amino acid, facilitating accurate protein synthesis.
