We can look at DNA to see that all organisms are related, just like people can take a DNA test to see whether they are related to a particlar person.

Identify two ways that organisms can be compared to provide evidence of evolution from a common ancestor?
You may use a brace map to determine common ancestors, look at physical structures of the skeletal system, or homologous genes.
Function of sodium acetate in DNA extraction?
Sodium chloride help to separate DNA from other proteins.
What happens when T2 phages are grown in the presence of radioactive phosphorus?
The bacterial proteins will become radioactive
Role of sodium chloride in DNA extraction?
Sodium chloride was needed to ensure the proteins in the cell aren't separated from the rest of the solution with the DNA.
What is the Radioactive molecule used to label proteins?
Proteins are labeled with radioactive amino acids so that they can be identified. Scientists use radioactivity to label proteins in order to track them during their experiments, you can follow protein degradation, label proteins that don't have antibodies, label all proteins produced at a certain time, separate proteins produced by intracellular pathogens from host proteins, among many other uses.
Why is DNA the weakest evidence of evolution?
Actually, it is the strongest evidence for evolution. Without one fossil we would know from the DNA evidence that evolution has occurred and is occurring. It is in the DNA of organisms that we see the strongest evidence for common ancestry. The products of those genes are sometimes highly conserved down the ages. Ribosomes, the workbenches on which proteins are made, differ hardly at at between you and pets.
Why do scientists study proteins to find evidence for evolution?
Proteins reflect DNA sequences, so scientists study proteins to look for genetic similarities and differences in organisms.
How can DNA and proteins provided evidence and evolution?
We can look at DNA to see that all organisms are related, just like people can take a DNA test to see whether they are related to a particlar person.
How do fossils provide evidence that evolution has taken place?
Fossils show evidence of evolution by showing a picture to the past and through some methods how DNA of one animal may be similar to that of a modern animal.
How fossil provide evidence that evolution has taken place?
Fossils show evidence of evolution by showing a picture to the past and through some methods how DNA of one animal may be similar to that of a modern animal.
What is the study that can provide evidence of evolution?
Fossils, patterns of early development, similar body structures, DNA, and protein structures.
What is the biochemical evidence that supports evolution?
DNA
What is the biochemical evidence that supports biological evolution?
DNA
What was the first stage of the process that lead to the a biotic origin of life?
In order to have DNA, you have to have 20 critical protiens for DNA to form. These proteins can only be derived from present DNA. This evidence points towards Creation rather than evolution.
The study of can provide evidence of evolution?
The study of: (i) Cladistics: regional biodiversity, race circles, and geographical isolation; (ii) Genetics: DNA, chromosomes, viral insertions, common mutations; and (iii) Paleontology: fossils. These are some of the types of evidence for evolution.
The parts of DNA that provide the code for proteins are the?
The parts of DNA that provide the code for protein are called genes.
The study of what can provide evidence of evolution?
The study of fossils, comparative anatomy, embryology, genetics, and biogeography can provide evidence of evolution. These fields help researchers understand how species have changed over time and how they are related to one another through common ancestors.
