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?
12 Because 1 nucleotide=1 Amino Acid.
How many nucleotides are necessary to code for a polypeptide that is 200 amino acids long?
In the genetic code, a sequence of three nucleotides forms a codon, which codes for one amino acid. So for each amino acid, there are three nucleotides. Therefore, 600 nucleotides are needed to make 200 amino acids.
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.
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!
What is the biological term for a nucleotide sequence which carries the code for a protein?
If the protein has a single chain of amino acids (known as a polypeptide chain), e.g. human growth hormone, then the term would be gene. A gene can be defined as a segment of DNA that codes for a polypeptide chain (or for a molecule of RNA, such as a molecule of transfer RNA or ribosomal RNA).If the protein has more than one chain, and the chains have different sequences of amino acids, then the code is carried in more than one gene: "one gene, one polypeptide".The nucleotide sequence that codes for just one of the amino acids in a chain is called a codon, and it consists of three adjacent nucleotides, often written just as the bases, because these are the only parts that differ between nucleotides. An example of a codon is CCA.

Which of the amino acids would whne incorporated into polypeptide chain make the charge of the polypeptide more positive?
Arginine
Which nucleotides would be found in the molecule?
Without knowing what molecule and which nucleotides, it is impossible to answer your question.
What is another name for a protein chain?
the answer would be.... polypeptide

What is the name for a large polymer of nucleotides that provides the code for making proteins?
DNA.It is the sequence of bases along the DNA molecule that codes for the sequence of amino acids in a polypeptide chain. One or more polypeptide chains, when they have correctly coiled and folded, and, if necessary, assembled together, form the functional molecule that we call a protein.In some viruses the genetic information is stored in RNA, not DNA, so a more accurate answer would be a nucleic acid.
What test would you run to test for the presence of a polypeptide?
Biuret test
How many nucleotides would it take to construct the mRNA coding strand of the β-subunit of the hemoglobin A molecule?
441 nucleotides
