Amino acids to Proteins?

Question

How do 2 Amino Acids turn to Proteins?

Answer 1

amino acids join together by a dehydration reaction that forms peptide bonds between the two amino acids.

Answer 2

The RNA sequence that is transcribed from the gene is then decoded by tRNA molecules, this process is known as translation. The instructions for making protein is stored in the DNA, which is then transcribed into mRNA which is then relocated to the cytoplasm of the cell. Where the mRNA molecules are then used as templates for the production of the proteins. How this works, the genetic code is stored in sets of three bases called a codon for example, CUA is the codon for leucine. How the translation work is the amino acids are carried to the mRNA on molecule of tRNA. At one end of the tRNA there is the amino acid at the opposite end is a sequence called the anti codon which is complimentary to the code, for leucine this would be GAU. Each individual amino acid has at least one codon, and a corresponding tRNA that is able to bind to the mRNA. Therefore each tRNA caries the anti-codon and its corresponding amino acids. The code contained in the mRNA will determine which tRNA bind the thus which amino acid will be inserted.

Please go to this diagram to see this process, it is better understood if you can visualises the process.

You can see the process happening in this diagram the tRNA brings the amino acid to the mRNA the amino acid is located at the opposite end from the anti-codon. as the tRNA bind to its complimentary sequences it lines up the amino acid. Which is then joined together to form an ever extending polypeptide or protein. therefore the mRNA determines what amino acid will be inserted next. And it is this sequence of the amino acids that will determine which proteins are made.

Answer 3

well this is a very complicated process.
First two amino acids will not form a protein but a dipeptide.
To make a prtn you need many polypeptides.
To form one polypeptide the process start in the nucleus where one gene induces the formation of one peptide this process is known as transcription: An enzyme will transcribe DNA into mRNA which will move outside the nucleus into the endoplasmic reticulum where ribosomes are present. The ribosome translate by the help of tRNA each triplets of mRNA nuclecleotides (codons) into an amino acid. A peptide bond will be formed there between two amino acids.
The process continues till a long polypeptide is formed.
Many polypeptides will be joined by hydrogen bonds to form a protein

Answer 4

process of translation which occurs in the ribosomes in the cytoplasm. a tRNA carries a different amino acid and using the sequence of the mRNA strand (transcribed in the nucleus of a cell), it joins to it. Translation is the second process of protein biosynthesis (part of the overall process of gene expression).Translation occurs in the cytoplasm where the ribosomes are located. Ribosomes are made of a small and large subunit which surrounds the mRNA. In translation, messenger RNA (mRNA) is decoded to produce a specific polypeptide according to the rules specified by the genetic code. This is the process that converts an mRNA sequence into a chain of amino acids that form a protein. Translation is necessarily preceded by transcription. Translation proceeds in four phases: activation, initiation, elongation and termination (all describing the growth of the amino acid chain, or polypeptide that is the product of translation). In activation, the correct amino acid (AA) is joined to the correct transfer RNA (tRNA). While this is not technically a step in translation, it is required for translation to proceed. The AA is joined by its carboxyl group to the 3' OH of the tRNA by an ester bond. When the tRNA has an amino acid linked to it, it is termed "charged". Initiation involves the small subunit of the ribosome binding to 5' end of mRNA with the help of initiation factors (IF), other proteins that assist the process. Elongation occurs when the next aminoacyl-tRNA (charged tRNA) in line binds to the ribosome along with GTP and an elongation factor. Termination of the polypeptide happens when the A site of the ribosome faces a stop (nonsense) codon (UAA, UAG, or UGA). When this happens, no tRNA can recognize it, but releasing factor can recognize nonsense codons and causes the release of the polypeptide chain. The capacity of disabling or inhibiting translation in protein biosynthesis is used by antibiotics such as: anisomycin, cycloheximide, chloramphenicol and tetracycline.

after the amino acids are joined by polypeptide bonds they form a primary level of a protein.
