Amino acid sequences are used in classification by comparing the similarities and differences in the sequences of proteins across different organisms. This comparative analysis can reveal evolutionary relationships, helping to classify species based on genetic lineage. Additionally, specific sequences can indicate functional traits, aiding in the identification of protein families and the understanding of biological processes. Ultimately, these sequences serve as crucial data for phylogenetic studies and taxonomy.
What else can I help you with?
Proteins can be used to determine how closely related organisms are because amino acid sequences are determined by an organism's?
genetic code. Organisms that share more similar amino acid sequences in their proteins are likely to be more closely related than those with differing sequences. This similarity can help scientists infer evolutionary relationships between different species.
What is the job of the ribosomes in cells?
The ribosome is used in mRNA translation. The ribosome reads codons of mRNA (transcribed from DNA) and translates them into an amino acid sequences. These amino acid chains then undergo various forms of coiling and folding into a finished protein.
What is the name of the machine that makes small sections of amino acid chains?
The machine is called a peptide synthesizer. It is used to assemble amino acids into specific sequences to create peptides.
What does an amino acid table show?
An amino acid table shows the 20 standard amino acids along with their three-letter and one-letter abbreviations, chemical structures, and properties such as polarity and charge. It provides a quick reference for researchers and students studying protein structure and function.
Is it possible for two people to have different DNA yet make the same amino acid?
Yes, it is possible for two people to have different DNA and still produce the same amino acid. This is due to the redundancy in the genetic code, where multiple codons (sequences of three nucleotides) can code for the same amino acid. Variations in DNA may lead to different codons being used, but they can still result in the same amino acid being synthesized during protein translation. Thus, despite genetic differences, the outcome in terms of amino acid production can be the same.
How can amino acid sequences be used to identify the source of a virus?
Amino acid sequences can be compared to databases of known viral sequences to identify the source of a virus. This comparison can reveal similarities between the amino acid sequences of the virus in question and those of known viruses, helping to determine its origin. By analyzing these similarities, researchers can infer relationships between different viruses and trace the evolutionary history of the virus in question.

. Explain how nucleic acid base sequences are used in phylogenetic classification?
Nucleic acid base sequences are used in phylogenetic classification to determine the evolutionary relationships between different species. By comparing the base sequences of organisms, researchers can identify similarities and differences, which can indicate how closely related species are to each other. This information is then used to construct phylogenetic trees that show the evolutionary history and relatedness of different species.
What are codon and anticodons?
Codon = 3 amino acid sequence found on mRNA. Anti codon = 3 amino acid sequence found on tRNA.The codons are for the traslation of mRNa to an amino acid sequence by using ribosomes.

How are differences between DNA amino acid sequence used to show relatedness between species?
Differences in DNA amino acid sequence are used to determine the degree of similarity between species. The more similar the amino acid sequences are between two species, the more closely related they are thought to be. This information helps scientists understand evolutionary relationships and build phylogenetic trees to show how different species are related to each other.
How do you determine amino acid sequences from Pka values?
The short answer is that you can't. Individual amino acids may be identified by their pI, the point at which they have an overall neutral charge, but finding the pKa of a protein as a whole can't conclusively give you the amino acid sequence of the protein. You may get a sense of whether the protein is acidic or basic overall though. There may be some way to do it if you have other factors involved in your experiment that you haven't divulged (i.e., a limited number of sequences that could be the answer or controls in the experiment), but the simple answer to your question is that it is impossible.

Is thymine an amino acid?
No, it is NOT, although it is often claimed to be. It is a sulfonic acid, but NOT an amino acid. Why not, you may ask? This is due to the scientific definition of how an amino acid has to be composed: Amino acids are defined as organic acids with an amino group (-NH2) and a carboxy group (-COOH) attached to a chain of carbon atoms of varying length. A look a the structural formula of taurine shows that this is clearly not the case: The hydroxy group (-OH) as well as the doubly bonded oxygen are attached to a sulfur atom and not to a carbon atom.
How can the amino acid codon wheel be used to determine the specific amino acid sequence in a given DNA sequence?
The amino acid codon wheel can be used to determine the specific amino acid sequence in a given DNA sequence by matching the DNA codons with their corresponding amino acids on the wheel. Each set of three DNA nucleotides (codon) codes for a specific amino acid, and by using the codon wheel, one can easily identify the amino acid sequence encoded by the DNA.
