How many ribosomes are needed for the production of a polypeptide containing thirty amino acids?
One ribosome is needed to synthesize a polypeptide containing thirty amino acids. The ribosome reads the mRNA and assembles the amino acids into a polypeptide chain according to the codons on the mRNA.
What does it mean to say that the genetic code is triplet?
Prior to understanding the details of transcription and translation, geneticists predicted that DNA could encode amino acids only if a code of at least three nucleotides was used. The logic is that the nucleotide code must be able to specify the placement of 20 amino acids. Since there are only four nucleotides, a code of single nucleotides would only represent four amino acids, such that A, C, G and U could be translated to encode amino acids. A doublet code could code for 16 amino acids (4 x 4). A triplet code could make a genetic code for 64 different combinations (4 X 4 X 4) genetic code and provide plenty of information in the DNA molecule to specify the placement of all 20 amino acids. When experiments were performed to crack the genetic code it was found to be a code that was triplet. These three letter codes of nucleotides (AUG, AAA, etc.) are called codons. The genetic code only needed to be cracked once because it is universal (with some rare exceptions). That means all organisms use the same codons to specify the placement of each of the 20 amino acids in protein formation. A codon table can therefore be constructed and any coding region of nucleotides read to determine the amino acid sequence of the protein encoded. A look at the genetic code in the codon table below reveals that the code is redundant meaning many of the amino acids can be coded by four or six possible codons. The amino acid sequence of proteins from all types of organisms is usually determined by sequencing the gene that encodes the protein and then reading the genetic code from the DNA sequence.
Where does tRNA move after this bonding of lysine to the polypeptide?
After bonding lysine to the polypeptide chain, the tRNA moves away from the ribosome as it is no longer needed for the process of translation. The ribosome then moves along the mRNA to the next codon, where another tRNA molecule carrying the next amino acid will come in to continue building the polypeptide chain.
How many codons are needed to code for a protein that has 50 amino acids?
Since each amino acid is encoded by a specific triplet of nucleotides (codon), you would need 50 codons to code for a protein that has 50 amino acids. Each codon corresponds to one amino acid, ensuring the correct sequence is produced during protein synthesis.
The one gene one polypeptide theory states that?
The one gene-one polypeptide theory states that for every gene one protein is synthesized n a cell. This theory has lost favor with the discoveries of post-translational modification, protein splicing and epigenetics, all of which support the production of multiple protein products from a single gene.
Triplet codes needed to produce a specific peptide chain comprise the makeup oa a?
gene
How many bases are needed to specify an mRNA codon?
3 bases are needed to specify an mRNA codon.
What is the smallest segment of DNA needed to produce a polypeptide or protein?
The smallest segment of DNA needed to produce a polypeptide or protein is a gene. A gene contains the instructions for making a specific protein through the process of transcription and translation. The gene includes sequences that code for the protein as well as regulatory regions that control its expression.
How many ribosomes are needed for the production of a polypeptide containing thirty amino acids?
One ribosome is needed to synthesize a polypeptide containing thirty amino acids. The ribosome reads the mRNA and assembles the amino acids into a polypeptide chain according to the codons on the mRNA.
How many nucleotides are needed to specify three acids?
Nine nucleotides are needed to specify three amino acids.
What molecule contains all of the codons needed to produce a particular polypeptide?
A single mRNA molecule has 3 codons i.e. 1 amino acid. The question is flawed and does not make sense!
Why is an insurance contract needed?
An insurance contract is needed to specify the exact terms of the insurance.

What if the first triplet was C A A?
If the first triplet in an RNA codon sequence was C A A, it would correspond to the amino acid lysine. Lysine is one of the essential amino acids needed for protein synthesis in the cell.
How many nucleotides are needed to specify one codon?
three.
What contains information to produce a single polypeptide?
Messenger RNA (mRNA) contains the information needed to produce a single polypeptide during translation. The sequence of nucleotides in the mRNA molecule is translated by ribosomes to determine the order of amino acids in the polypeptide chain. This process occurs in the cytoplasm of the cell.
Which chemical reactions would be needed to convert a polypeptide into small subunits?
Proteolysis is a chemical reaction that would be needed to convert a polypeptide into small sub-units. By definition, proteolysis is the breakdown of proteins into smaller polypeptides or amino acids. The breakdown occurs through a process called hydrolysis in which the chemical bonds are separated by the addition of water.
