The similarity in amino acid sequences between different species often reflects their evolutionary relationship, with closely related species typically sharing a higher degree of sequence similarity. This is due to the conservation of essential proteins and functions over time, as evolutionary pressures favor maintaining certain amino acid sequences. Consequently, examining these sequences can provide insights into phylogenetic relationships, helping to trace lineage divergence and evolutionary history. Overall, the closer the amino acid sequences, the more likely the species are to have a common ancestor.

During protein synthesis the nucleotide sequence specifies a particular species of?
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.
What is differ ence between the amino acid sequences of the hemoglobin in humans and the hemoglobin in frogs?
The amino acid sequences of hemoglobin in humans and frogs are different due to evolutionary divergence. While both hemoglobins are composed of similar building blocks (amino acids), the specific sequence of amino acids varies between species. This divergence in sequence reflects the adaptation of these proteins to meet the specific oxygen-carrying needs of each species.
What chain is a sequence of amino acids that is the foundation for the basic structure of a protein?
A polypeptide chain is a sequence of amino acids that forms the primary structure of a protein. This chain is held together by peptide bonds between adjacent amino acids.
How is the nitrogen base sequence of a gene related to the structure of a protein?
The sequence of nitrogenous bases (A, T, G and C) forms a code for the sequence of amino acids in a protein. The code is a triplet code. This means that three bases code for one amino acid. So, the order of the bases in a gene determines the order of the amino acids in a protein.
How did scientist find that human genes that make insulin?
Scientists used the amino acid code to find the DNA base sequence,i.e. they worked backwards from mRNA to DNA.They figured out the DNA sequence from the amino acid sequence- APEXthey figured out the dna sequence from the amino acid sequence
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.

What does the genetic code specify the correlation between?
The genetic code refers to the nucleotide triplets of DNA and RNA molecules that carry genetic information. It specifies the correlation between an RNA-nucleotide sequence, as well as an amino-acid sequence.
What influences protein shape that determines protein function?
Amino acid sequence primarily determines a proteins shape, but secondary (alpha helix and beta sheet) and tertiary structures (Hydrogen bonding, other chemical bonding between structures) adds to it.
What is the relationship between a nucleotide sequence and an amino acid sequence in the process of protein synthesis?
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.
What is the relationship between the linear sequence of codons on mRNA and the linear sequence of amino acids in a polypeptide?
The linear sequence of codons on mRNA corresponds to the linear sequence of amino acids in a polypeptide through the process of translation. Each three-nucleotide codon on the mRNA molecule codes for a specific amino acid, and the sequence of codons determines the order in which amino acids are added to the growing polypeptide chain. This relationship is known as the genetic code.
What determines the shape of proteins?
The sequence of amino acids. The chemical bonds between amino acids, and temperature and ph. and its environment
How does the variation in protein reflect changes in a species DNA?
As new species evolve they build up differences in the DNA from related species, as a result of mutation and selection. The role of DNA is to encode the structure of proteins. The DNA code defines the sequence of amino acids in each protein. So if the sequence of bases in the DNA changes, the sequence of amino acids in the proteins can also change as a result. If we compare closely related species there should be fewer differences in their DNA and so fewer differences in their proteins than between distantly related species. By comparing amino acid sequences we can therefore estimate how closely or distantly related two species are to each other. (see related links)
How many human amino acids are the same as the chicken amino acids?
Amino acids are chemicals, it doesnt matter from which organism it is, they are chemically the same (for example Glycine is an amino acid, it is the same in any species).What will iffer is, the sequence of amino acids that make proteins (such as Glycine alanine valine tyrosine is a sequence may not be same like phenylalanine serine glutamine aspartate)
What is the difference between synonymous and nonsynonymous substitutions in genetic mutations?
Synonymous substitutions in genetic mutations do not change the amino acid sequence of a protein, while nonsynonymous substitutions do alter the amino acid sequence.
What determines the amino acid sequence in a protein?
The sequence of amino acids in a protein is determined by the sequence of nucleotides in the mRNA, and this is determined by the sequence of nucleotide bases in the DNA.
