A polypeptide found in the cytoplasm of a cell contains 12 amino acids How many nucleotides would be required in the mRNA for this polypeptide to be translated?
Since each amino acid is coded for by a specific triplet of nucleotides (codon), and there is a start codon and a stop codon, we need 15 nucleotides in the mRNA (3 nucleotides for each amino acid + 3 for start codon + 3 for stop codon).
How many nucleotides are necessary to code for a polypeptide that is 200 amino acids long?
A minimum of 600 nucleotides is necessary to code for a polypeptide that is 200 amino acids long because each amino acid is coded for by a sequence of three nucleotides in mRNA. This is due to the genetic code being triplet, where every three nucleotides represent one amino acid.
If the adenine nucleotides were deleted how many amino acids would be coded for in a polypeptide chain made from this sequence agucuugggcuuugcccc?
AGUCUUGGGCUUUGCCCC If the Adenine nucleotides were deleted then both the A and U nucleotides would be affected. Only the G and C would be allowed to code for the protein. GCGGGCGCCCC would be the resulting sequence. A codon is made of three nucleotides. So: GCG GGC GCC CC G CGG GCG CCC C GC GGG CGC CCC would be the only sequences that could result. This would be only three amino acids.
List the amino acids in the order they would appear in the polypeptide coded for by the mRNA?
The order of amino acids in a polypeptide is determined by the sequence of codons in the mRNA. The genetic code determines that specific codons correspond to specific amino acids. The mRNA is read in sets of three nucleotides (codons), each of which codes for an amino acid, resulting in the correct sequence of amino acids in the polypeptide.
How does insertion or deletion affect a polypeptide chain?
Nucleotides in the coding region of DNA are transcribed into mRNA. mRNA, in turn, is translated into a polypeptide via the ribosome. Three (3) nucleotides correspond to one amino acid. In other words, if the nucleotides in question are AAA, those nucleotides will be transcribed into their mRNA complement, UUU, which in turn will be translated into the amino acid phenylalanine via the ribosome. Now, if you remove one of those nucleotides, say the first A of the AAA, everything gets screwed up. You get what is caused a frameshift. Say originally you had AAAUAG. As I mentioned, AAA would eventually become phenylalanine, and UAG is a stop codon, which would tell the ribosome to stop translating: the polypeptide is complete. But if the first A of the AAA is removed -- the ribosome still wants to read in threes! So it will read AAU, and code asparagine instead of phenylalanine, and moreover . .. it will keep translating making a polypeptide much longer than evolution intended!
How much nucleotides for 150 polypeptide?
To calculate the number of nucleotides required to code for a specific polypeptide, you need to know the number of amino acids in the polypeptide. Since each amino acid is coded by a codon made up of three nucleotides, you would need 3 times the number of amino acids to determine the total number of nucleotides required. For a 150 amino acid polypeptide, the number of nucleotides would be 150 (amino acids) * 3 (nucleotides per amino acid) = 450 nucleotides.
What is the maximum length of a polypeptide encoded by an mRNA that is 45 nucleotides long?
The maximum length of a polypeptide encoded by an mRNA is determined by the number of nucleotides in the mRNA sequence. Each amino acid is encoded by a set of three nucleotides called a codon. With a 45-nucleotide mRNA sequence, the maximum length of the polypeptide would be 45/3 = 15 amino acids.

What is another name for a protein chain?
the answer would be.... polypeptide
How do you make a 10 codon sequence for a polypeptide?
To create a 10 codon sequence for a polypeptide, you would need to transcribe a DNA sequence into an mRNA sequence. Each codon consists of three nucleotides. Look for the start codon (AUG) to begin the sequence and then continue adding codons until you have 10 in total.

Which nucleotides would be found in the molecule?
Without knowing what molecule and which nucleotides, it is impossible to answer your question.
Which of the amino acids would whne incorporated into polypeptide chain make the charge of the polypeptide more positive?
Amino acids with positively charged side chains, such as lysine, arginine, and histidine, would make the overall charge of a polypeptide more positive when incorporated into the polypeptide chain. These amino acids have side chains that can interact with negatively charged groups, leading to a net positive charge in the polypeptide.
A chain of 67amino acids would be called?
A chain of 67 amino acids would be called a peptide or a polypeptide, depending on the context in which it is being referred to. Peptides typically consist of fewer than 50 amino acids, while polypeptides are longer chains of amino acids.
