What is the most useful fact in determining whether two organisms are related?
DNA sequence similarity is the most useful factor in determining whether two organisms are related. The more similar the DNA sequences of two organisms are, the more closely related they are likely to be evolutionarily.
What does the presence of similar DNA sequences in the genes in very dissimilar organisms imply?
The presence of similar DNA sequences in genes of very dissimilar organisms implies a common ancestry or evolutionary relationship. These similarities suggest that these organisms share a common ancestor and have inherited these sequences through evolution.
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.
How are DNA sequences used for classification?
DNA sequences are used for classification by comparing the genetic information of different organisms. By analyzing the similarities and differences in their DNA, scientists can determine the evolutionary relationships between species and classify them into different groups based on their genetic relatedness. This method, known as molecular phylogenetics, helps to create more accurate and reliable classification systems compared to traditional methods based on morphology or behavior.
What technology allows scientists to compare the DNA of different kinds of organisms to determine classification?

Why are DNA sequences more similar in more closely related organisms?
DNA sequences are more similar in closely related organisms because they share a common ancestor and have undergone fewer genetic changes over time. As organisms diverge and evolve, mutations accumulate in their DNA, leading to differences in their genetic sequences. Therefore, closely related organisms have had less time to accumulate mutations, resulting in more similar DNA sequences.
What is the most useful fact in determining whether two organisms are related?
DNA sequence similarity is the most useful factor in determining whether two organisms are related. The more similar the DNA sequences of two organisms are, the more closely related they are likely to be evolutionarily.
Why is DNA a useful piece of evidence in studying evolution?
DNA is a useful piece of evidence in studying evolution because it carries genetic information that can show how species are related and how they have changed over time. By comparing DNA sequences, scientists can track evolutionary relationships and understand how organisms have evolved and adapted to their environments.

What does the presence of similar DNA sequences in the genes in very dissimilar organisms imply?
The presence of similar DNA sequences in genes of very dissimilar organisms implies a common ancestry or evolutionary relationship. These similarities suggest that these organisms share a common ancestor and have inherited these sequences through evolution.
How does shotgun sequencing work to sequence DNA fragments?
Shotgun sequencing breaks DNA into small fragments, sequences them, and then assembles the fragments to create the full DNA sequence. The process involves randomly breaking the DNA into pieces, sequencing each piece, and then using overlapping sequences to piece together the entire DNA sequence.
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.
The more similar the DNA sequences of two species are the more closely related the species are?
Yes, that's correct. Species with more similar DNA sequences are considered more closely related evolutionarily since they share a more recent common ancestor. This similarity in DNA sequences is used to construct phylogenetic trees and understand the evolutionary relationships between different species.
Which are more conserved DNA or protein sequence?
Protein sequences are generally more conserved than DNA sequences because of the redundancy in the genetic code. Mutations in DNA can sometimes result in the same amino acid being coded for, so changes in DNA sequences do not always lead to changes in protein sequences. Additionally, certain protein sequences are critical for their function, making them more constrained and therefore less likely to change.
All organisms have a genetic code made of?
All organisms have a genetic code made of these three nucleotide sequences called codons.
How can one create a phylogenetic tree from DNA sequences?
To create a phylogenetic tree from DNA sequences, scientists use bioinformatics tools to compare the genetic information of different species. They analyze the similarities and differences in the DNA sequences to determine evolutionary relationships and construct a branching diagram that represents the evolutionary history of the organisms.
