How does the sequence of DNA affect the function of a protein?
The sequence of nucleotides in DNA molecule is equivalent and is closely related to an amino acid sequence in the protein molecule. If for any reason the sequence of DNA nucleotides changes it will be reflected in amino acid sequence in the protein. Moreover, the correct sequence of amino acid in the protein will form the correct three-dimensional structure, or tertiary structure, that will confer the biological activity to protein. If a wrong amino acid is translated from a mutated gene in the DNA could change the spatial structure of the protein and therefore modify or erase its biological function.
What is the term for a 3-nucleotide sequence on mRNA that codes for an amino acid?
the three nucleotides on a mRNA that codes for a amino acid is called a codon
What is the combination of three mRNA nucleotides?
Three sequential mRNA nucleotides are called a codon, which codes for one amino acid.
What are three nucleotides that together specify one amino acid?
TRIPLET CODE
How is the placement of the amino acid during translation is determined by the?
During the translation process, the translation machinery reads the sequence of nucleotides present on the mRNA. The sequence of nucleotides on mRNA is divided in codons, these are set of three nucleotides. There are total 64 codons that contiguously present on mRNA. corresponding to each mRNA codon there is a tRNA that has an anticodon loop that has three nucleotide complementary to the codon. Now Anticodons bind to their specific amino acid called as the charging of the tRNA and carry to the mRNA that is bound to ribosome. The catalytic activity of the 16s rRNA leds to the formation of peptide bond between the coming and the already added 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.
What is another name for three nucleotides in a row which encode for a protein?
A sequence of three nucleotides is a codon which codes for an amino acid that will be placed into a protein.
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 many bases on a strand of mRNA code for one amino acid?
3 nucleotides
What is the nucleiotide sequence in mRNA that determines a specific amino acid?
groups of three nuleotides in mRNA codes for each one specific amino acid, these groups of three nucleotides are called as codon
What is the three nucleotide?
Messenger RNA (mRNA) serves as the primary transcript, and its nucleotide sequence determines the amino acid sequence of proteins. A codon in mRNA comprises of three nucleotides that encode a specific amino acid. For example, the codon for glutamine is CAG (Cytosine, Adenine and Guanine). The most common stop and start codon is TAA and AUG respectively.
How does an insertion sequence cause a mutation?
In the DNA, the sequence of nucleotides determines how proteins are built, with each segment of three nucleotides encoding a single amino acid. When one nucleotide is inserted into the sequence, the whole sequence shifts, and all the triples are changed completely, which can cause detrimental mutations.
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.
The number of nucleotides required to specify an amino acid is?
Three nucleotides are required for an amino acid. These nucleotides are an amine, carbolic acid, and a side chain specific to the amino acid.
How does DNA contain instructions for traits?
The DNA code consists of specific sequences of DNA nucleotides that code for specific amino acids. A sequence of three nucleotides are called a codon, and code for one specific amino acid. The sequence of amino acids determines the structure and function of the proteins, which determine the cells' activities and hereditary traits.

What is the difference between a coden and an anti coden?
a codon is the sequence of three nucleotides of mRNA, the anti codon is the amino acid of tRNA that is matched to the codon.
