Why are there only 45 different tRNA anticodons rather than 64 to match each of the mRNA codons?

The third nucleotide of a tRNA anticodon allows some flexibility or "wobble."

What is the difference between mRNA and tRNA?
mRNA is the RNA that carries information during transcription and translation. It has codons, which match up with the anticodons on tRNA. tRNA is the RNA that bonds to amino acids and transfers them to ribosomes, and mRNA.
How does the structure of tRNA relate to its function in translation?
The function of tRNA includes the transfer of amino acids to ribosome, matching the anticodon with an amino acid, and forming hydrogen bonds between anticodons and mRNA codons. Because the amino acid and anticodons are at the ends of the RNA it will be able to match together, its small size allows it to transfer amino acids to the ribosome, and since the anticodon is at the end of the tRNA it will be able to form hydrogen bonds with mRNA codons.
How do the 3 types of RNA work together to complete Translation?
In the first stage, mRNA copies instructions from the DNA in the nucleus of the cell. Then, the mRNA travels out to the cytoplasm, where it meets up with a ribosome (also called rRNA). The ribosome starts to "decode" the mRNA into a protein by bringing in tRNA molecules with the anticodons to match the codons on the mRNA. Each tRNA has an amino acid attached to the end, and when the codons and anticodons match up, this amino acid is released and attached to the growing chain. In the end, you have a twisted chain of amino acids, which we scientific people call a protein. :)
What is the relationship between codons and anticodons?
A codon is found in the DNA sequence and in the mRNA sequence. The anticodon is the opposite sequence that would match with the sequence of the codon and allows pairing of the anticodon with the codon
What are the nucleotide sequences of tRNA that are complementary to codons on mRNA?
The base sequences on tRNA that are complementary to the codons on mRNA are known as anti-codons. These match up with the codons to ensure the correct amino acid is added to the polypeptide (protein) chain being created. U binds with A, G binds with C.

Why are condons and anticondons important?
its codons and anticodons and they determine the alanine, cytosine, guanine, thymine, and urcail in amino acids. without them we wouldn't have DNA and no one would be here. they match up DNA strands to determine your genotype and phenotype. i know it sounds like a bunch of jibber jabber but that's what it is haha.
Can an amino acid be specified by more than one codon?
Yes, each amino acid has several codons that correspond to it. Please see the related link for a chart which shows this. For example, UUU and UUC both code for Phenylalanine. However, if you are asking if a codon can code for more than one amino acid, the answer is no (but there are exceptions). This means that UUU codes for Phenylalanine - not for any other amino acids. Codons are made in sets of three bases to match the anticodons in corresponding sets of three bases.
What is the process of transferring a genes instruction for making a protein to an rns molecule?
The whole process of protein synthesis can be referred to as translation. An mRNA strand binds to the ribosome where a complementary strand of tRNA matches up at the ribosome. Groups of three nucleotides known as codons on mRNA match up with groups of three nucleotides known as anticodons on tRNA. Each set of codons and anticodons code for an amino acid. The mRNA strand moves down the ribosome codon by codon creating amino acid by amino acid and binding them together with peptide bonds. This long chain of amino acids is known as a polypeptide or protein. Once the mRNA strand is completely coded for, the protein is released into the cell to perform its desired function.
What carries the instructions for making protein?
mRNA is the complementary strand of DNA that leaves the nucleus of the cell and binds to the ribosome. The mRNA is what carries the instructions for creating proteins. mRNA binds to the ribosome and a complementary strand of mRNA (tRNA) also binds to the ribosome. Groups of three nucleotides on the mRNA, known as codons, match up with groups of three nucleotides on the tRNA, known as anticodons. The codons and anticodons code for amino acids. The ribosome moves down the mRNA strand until it has all been coded for and the amino acid chain is released into the cell to perform it's desired funtion. It's a cytokine (a signalling protein) that has lots of different effects depending on what cell is exposed to it. In this case, the researchers think it may be doing something to the cells that maintain ear bones.
What molecule would you find anticodon?
In the protein/metabolic RNA molecule called transfer RNA. This molecule pichs up individual amino acids in the cytosol and brings them one at a time to the ribosome where the end of the molecule bearing the anticodon docks on the ribosome and adds it's amino acid to the growing polypeptide chain.
Which molecules match mRNA codons to specific amino acids?
Starting from the translation start codon in the mRNA molecule, each three bases corresponds to a single amino acid, until you reach the stop signal. Some amino acids have more that one triplet that codes for them (redundancy). Some parts of the mRNA molecule are untranslated and therefore do not correspond to amino acids.
What is the relationship between codons and anticodons?
A codon is found in the DNA sequence and in the mRNA sequence. The anticodon is the opposite sequence that would match with the sequence of the codon and allows pairing of the anticodon with the codon
Why are there always an equal number of nitrogen bases?
because the codons will continue the same letters and will match up the same way that it did so it will repeat itself over and over again.
