During protein synthesis, the nucleotide sequence specifies a particular species of amino acid. This is accomplished through the genetic code, where a sequence of three nucleotides (codon) corresponds to a specific amino acid. The sequence of codons ultimately determines the sequence of amino acids in a protein.
The nucleotide sequence cucaagugcuuc represents a specific mRNA sequence that codes for specific amino acids during protein synthesis. Each set of three nucleotides, called a codon, corresponds to a particular amino acid or a stop signal in the genetic code.
The terminator in mRNA synthesis is a specific DNA sequence that signals the end of transcription. When the RNA polymerase reaches the terminator sequence, it stops transcribing the mRNA molecule, releasing it from the DNA template.
During protein synthesis, a nucleotide sequence in DNA is transcribed into a messenger RNA (mRNA) sequence. This mRNA sequence is then translated into an amino acid sequence by ribosomes. Each set of three nucleotides in the mRNA, called a codon, corresponds to a specific amino acid. This relationship between nucleotide sequences and amino acid sequences is crucial for the accurate assembly of proteins in the cell.
RNA uses uracil instead of thymine in its nucleotide sequence because uracil is more stable and efficient for the rapid synthesis of proteins during protein synthesis. Thymine is typically found in DNA, while uracil is specific to RNA.
No, AGG is not a codon. Codons are three-nucleotide sequences in mRNA that code for specific amino acids during protein synthesis. AGG is a nucleotide sequence present in DNA but does not directly code for an amino acid.
A substitution mutation is a type of genetic mutation where one nucleotide in the DNA sequence is replaced with a different nucleotide. This can lead to changes in the amino acid sequence during protein synthesis, potentially altering the function of the protein. The impact of a substitution mutation on the genetic code depends on where it occurs and what specific nucleotide is substituted.

It carries the instructions from DNA out into the cytoplasm.
A mutation in a DNA nucleotide sequence would be more harmful than a mutation in a mRNA nucleotide sequence because it could cause the synthesis of multiple nonfunctional proteins in comparison to a mutation in a mRNA nucleotide sequence that would be less harmful because it would result in a few nonfunctional proteins.
The entire sequence of DNA bases responsible for the manufacture of a protein or part of a protein is called a gene. Genes contain the instructions for making proteins through a process called protein synthesis, involving transcription and translation. Each gene has a specific sequence of nucleotide bases that encodes the information for a particular protein.
