I don't understand your question. mRNA does not have triplets. Did you mean codon? Triplet refers to DNA, codon to mRNA.

What are three nucleotides that together specify one amino acid?
TRIPLET CODE
How many nucleotides are need to code one amino acid?
3
How do nucleotides provide nucleic acid's with specific codes?
Nucleotides are merely the building blocks of nucleic acids like DNA and RNA. The specific order of these nucleotides are read in triplet form (AAC, ATA, etc.) as codons (which code for amino acids), and the combinations of these codons make up genes (which code for proteins).
Do DNA have codons?
Yes, DNA has codons. Codons are three nucleotides of DNA which code for a single amino acid.
Is it true point mutations that involve the insertion or deletion of a nucleotide change the reading frame of the genetic message?
Yes. Nucleotides are read in triplet code (i.e. AAA, CCC) and each set of three nucleotides represents an amino acid. Therefore if you had a line of nucleotides, and you removed or added one in the line you would be changing how the code is read. Observe if you had ACGAGUGAU. It is read as ACG-AGU-GAU - which represents threonine-serine-aspartic acid. Now, if we remove the first A, the new code is CGAGUGAU to which the reading frame is - CGA-GUG-AU. This would even change the amino acids the code was describing. It is now - Argenine-Valine and an incomplete third code.

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.
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.
How many nucleotides are required to encode one amino acid?
A codon, or a 3-base code is required to code for one amino acid.
How many nucleotides are need to code one amino acid?
3
How many amino acids would the a nucleotide have?
3 nucleotides code for 1 amino acid
How many bases on a strand of mRNA code for one amino acid?
3 nucleotides

What does a group of three nucleotides code for?
DNA nucleotides 'code' for RNA copies of the DNA strand, but the true 'coding' of nucleotides happen in the ribosome where amino acids are matched to the RNA nucleotides. Nucleotides in DNA are only are present to store genetic data. When a particular gene needs to be used or a protein needs to be made, a RNA copy of the DNA will be made, using the slightly different RNA nucleotides (adenine, uracil, cytosine and guanine). This copy then leaves the nucleus and travels to the ribosome, where the RNA nucleotides are used to assemble amino acids into proteins. Each amino acid matches up to a three-nucleotide sequence.
How do nucleotides in the RNA molecule code for various amino acids How many nucleotides code for one amino acid?
Each nucleotide is made up of an organic base, a pentose sugar and a phosphate. Nucleotides can be arranged in various different orders and that order dictates which amino acid it codes for, three amino acids code for one nucleotide. Is this enough detail?
What is the triplet code on mrna called?
The triplet code on mRNA is known as a codon. This 3-base sequence codes for a specific amino acid to be added to the chain (i.e. protein) being created.
