What is difference between flocculation and precipitation?
PrecipitaionLets take protein in water as a solution as an example. Protein consists of hydrophobic amino acids and hydrophilic amino acids. Hydrophobic amino acids are usually seen in the protein core and hydrophilic aminoacids forms hydrogen bond with water molecules. When an organic solvent, or salt is added to the solution water molecules which are in hydrogen bond with the hydrophilic amino acids break the bond and binds with the salt or solvent. Thus protein protein interaction becomes stronger than protein -water interaction. So due to partial dipole interaction and electrostatic force of attraction protein molecules aggregate and precipitate.FlocculationConsider a solution of proteins. If the solution is agitated continuously the protein molecules come together. If the agitation is that stronger effect to overcome the electrostatic force of repulsion between the protein molecules, they will cling together and forms floc. Another method is adding chemicals called flocculants. By adding floculants the electrostatic repulsion between the protein molecules can be reduced and this will lead to attraction of protein molecules and formation of floc.
Is tRNA attached to an amino acid?
Amino acids are attached to one end of the transfer RNA molecules and the other end of the tRNA moleule attaches to the a-site of the ribosome.
What is the role of tRNA in translation?
tRNA is used to carry the 20 different amino acids dissolved in the cytoplasm to the ribosomes to help build the polypeptide chain for proteins to be synthesized. Each tRNA molecule attaches to one type of amino acid.
What type of bonds are in a protein?
The atoms present in a protein molecule are bonded to each other by covalent bonds. Added: I think the questioner wants...., A special amide bond called a peptide bond binds the amino acid subunits together and in a folded protein you will get hydrogen bonds, hydrophyllic bonding, hydrophobic bonding and covalent sulfur-sulfur bonding to name several types.
What is the result of the translation process?
An amino acid chain
What process is used to link amino together?
Condensation(removal of a water molecule) links amino acids together to form chains called polypeptides. Protein synthesis possibly? Technically what forms the actual bond between the amino acids is dehydration, where an enzyme binds to the amino acids, and removes any H2O, and thus a bond is formed.

How do amino acids make up protines?
Through a process called translation. The mRNA travels from the nucleus to the cytoplasm and binds to a ribosome. The sequence of 3 nucleotides in the mRNA correspond to a certain amino acid that binds to the top of the ribosome and then the mRNA keeps getting read, 3 nucleotides at a time, until there are 20 amino acids binded together. The ribosome then lets the protein go.
What is a small protein with a high proportion of positively charged amino acids that binds to the negatively charged DNA and plays a key role in it chromatin structure?
histone
What is the function of tRNA.?
tRNA mediates recognition of the codon and provides the corresponding amino acid. It mainly is recognized for carrying amino acids. It then gives to it mRNA to translate the nucleotides proteins.
How do you make proteins?
DNA gets split into single strands, It is then copied to form mRNA. The mRNA is then transported from the nucleus to the cytoplasm where the ribosome binds, reads the mRNA strand and tRNA's carrying amino acids are joined together. The tRNAs bind due to their complimentary nucleotides, each amino acid has a triplicate of codons, all amino acids have different codons that all code for that amino acid. As the amino acid chain grows from the ribosome the protein chain grows.
What are the differences between codon anticodon?
Codons are three bases on mRNA which go to the ribosome which translates into amino acids. The amino acids are attached to tRNA which has the anticodon on it which will bind to the codon on the mRNA. This is how the ribosome picks out the correct amino acid. the tRNA with the anti codon just binds to the codon and the amino acids start binding together via peptide bonds.

Which of the following brings amino acids into a ribosome to be assembled into a protein?
transfer RNA (tRNA) attaches to amino acids and transports them to ribosomes, the site at which amino acids are assembled into proteins.I hope that helps!
What organelle synthesized protein?
Ribosomes.The only organelle that make proteins is ribosomes. DNA is the genetic material that codes mRNA and proteins. mRNA binds to tRNA and enzymes in ribosomes to form peptides from the amino acids.
What chemical bond is when the amine group binds to the acid group of amino acids?
That bond is called as peptide bond.
