Yes, all cells do and need to make their own proteins. All cells contain ribosomes for the absolute necessity for proteins to be present in and around the cell. However, there is an exception. Red blood cells, although they contain some ribosomes, lack a nucleus, which means that they are unable to translate any mRNA and form proteins. All the proteins that red blood cells need are formed during the making of the red blood cell.

What controls the bonding of specific amino acids to their correct tRNAs in a cell?
It's the enzyme amino-acyl-tRNA. It bonds the correct amino acid to the tRNA based on the anti-codon on the tRNA.
Compare and contrast the structure of tRNA and mRNA?
tRNA is transcription and transportation. mRNA is a messenger RNA it helps convert the codes for DNA. They both help to make proteins and peptide bonds.
In an analogy between a factory and a cell if DNA is the superintendent and mrna is the order to the assembly line what might be the role of trna?
tRNA would be the assembly workers.
Where in the cell do mRNA and amino acids on tRNA's come together to make a protein?
During translation, tRNA anticodons pair with the complementary mRNA codons at the ribosomes. Each tRNA molecule carries with it an amino acid according to its specific code. As each tRNA releases its amino acid, peptide bonds form between the amino acids. After each tRNA releases its amino acid, it is free to pick up another amino acid in the cytoplasm.
Is RNA single or double strand?
RNA is single stranded. DNA is double stranded. There are many types of RNA including mRNA, tRNA, and rRNA. mRNA and tRNA are involved in protein synthesis and the process of translation. mRNA and tRNA bind to the ribosome and form polypeptides or proteins that are released into the cell.
What part of the cell s tRNA found in?
tRNA, or transcription RNA is found in the Nucleolus when not being used, it goes to the ribosomes to help make proteins.
What result would you expect if you mutate one of the four arms of a tRNA?
The tRNA will not be recognized by tRNA synthetase and cannot be charged.
Are ribosomes part of the machinery the cell uses to make proteins?
Yes, along wth mRNA & tRNA
Tools help a cell translate an mRNA message into a polypeptide?
Ribosomes and tRNA molecules help a cell translate an mRNA message into a polypeptide.
In what part of the cell is tRNA found?
tRNA is in the cytoplasm where it picks up amino acids and takes them to the ribosomes during translation.
What tools that help a cell translate?
The main tools involved in the process of translation in a cell are ribosomes, transfer RNA (tRNA) molecules, messenger RNA (mRNA), and various protein factors. Ribosomes act as the machinery where translation occurs, while tRNA molecules bring amino acids to the ribosome based on the mRNA codon sequence. Protein factors help in initiating, elongating, and terminating protein synthesis.
What controls the bonding of specific amino acids to their correct tRNAs in a cell?
It's the enzyme amino-acyl-tRNA. It bonds the correct amino acid to the tRNA based on the anti-codon on the tRNA.
What creates ribosomes that are found inside the cell?
The nucleolus creates ribosomes out of rRNA and puts them into the rough endoplasmic reticulum to recieve mRNA to decode (with the help of tRNA) and make proteins from the amino acids (provided by tRNA) coded in mRNA.
How a cell make protein?
Cells make proteins through the process of protein synthesis, which starts with transcription of the DNA code by mRNA, and ends with translation by tRNA on the ribosomes.
Compare and contrast the structure of tRNA and mRNA?
tRNA is transcription and transportation. mRNA is a messenger RNA it helps convert the codes for DNA. They both help to make proteins and peptide bonds.
In an analogy between a factory and a cell if DNA is the superintendent and mrna is the order to the assembly line what might be the role of trna?
tRNA would be the assembly workers.
How does the cell know which enzyme to make and how to make it?
Enzymes are proteins. Thus, DNA codes the enzyme's information to an mRNA strand, which then is translated by tRNA into an anticodon. This takes place on the ribosome.
