What part of the dna sequence would be involved if the trna amino acid was agc?
An RNA codon which reads "UCG" would pair with a tRNA molecule which has the anti-codon "AGC".
Is the nucleotide sequence in an mRNA codon an exact copy of the DNA triplet that coded for it?
No. It's the RNA nucleotides that code for the DNA. The tRNA then in turn codes for a specific protein. So, for example, if the DNA sequence is TAG, the tRNA is AUC. (Uracil replacing thyamine in RNA)
Why does the cell need both mRNA and tRNA in order to synthesize a protein like hemoglobin?
DNA and RNA (m and t) are made of nucleotides. Proteins like hemoglobin are composed of amino acids. The mRNA specifies the sequence information needed for making the hemoglobin protein. This information is a direct and temporary copy of information contained on a gene on DNA. The tRNA is a separate molecule the carries an amino acid on it. It is like a mediator. It has sequence that matches to a small part of the sequence being specified by the mRNA. When the tRNA moves into the right position on the mRNA, the amino acid detaches from the tRNA and is added to the growing protein or polypeptide chain.
Is a trna anticodon more similar to DNA or RNA in nucleotide sequence?
The question has its answer, tRNA is a type of "RNA" so they would not be expected to be similar to DNA. Anticodon is just a three nucleotide in the tRNA (like codons in mRNA.DNA is a -deoxy ribose (oxygen is removed at 2' position) containing polymer and RNA doesnt have -deoxy but only the normal oxy (oxygen is not removed) sugar. so chemically or biophysically, they cant be as same as DNA.
Where do you find the nucleotides?
DNA, mRNA, and tRNA
If the DNA sequence is TAG what is the sequence of the complementary strand of tRNA?
auc
What order of bases on mRNA will match a sequence on tRNA of UUA?
If the tRNA has the sequence UUA, then the mRNA it reads from will have the sequence complementary to UUA, which is AAU. RNA uses the nucleic acid uracil instead of the DNA counterpart, thymine.
Where do you find anticodon?
The anti-codon is the molecule of mRNA in the nucleus which copies the codon from DNA in reverse. This process is reversed again when tRNA copies the mRNA in reverse, thereby restoring the original codon sequence.

How Can I Compare new double-stranded DNA models with an original DNA Model?
Please elaborate. If you mean how to compare the replicated DNA molecule with the original, there is no point because the replicated DNA molecule is an EXACT copy of the original.
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
Compare and contrast the structure of tRNA and mRNA?
tRNA is transcription and transportation. mRNA is a messenger RNA it helps convert the codes for DNA. They both help to make proteins and peptide bonds.

Which molecule determines the sequence of amino acids in a protein?
At the heart of it, DNA is the molecule that codes for the sequence of amino acids. DNA does this somewhat indirectly because its code is transcribed to mRNA, whose codons pair with specific tRNA anticodons, which are associated with a specific amino acid.

If anticodon on trna is gua what were the nucliotide coded by DNA?
GTA. What ever is on the tRNA will also be on the DNA codon. You can also work this out backwards. tRNA Anticodon reads GUA mRNA codon reads CAU DNA reads GTA
