Can mutations cause changes in DNA sequences?
mutations
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.
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.
How does DNA sequences can provide evidence of evolution?
DNA sequences can provide evidence of evolution by showing similarities and differences in the genetic code of different species. By comparing DNA sequences between species, scientists can identify common ancestors and evolutionary relationships. Changes in DNA over time, such as mutations and genetic variations, can also provide clues about how species have evolved and adapted to their environments.

If the amino acid sequences are similar in gorillas and humans why would you expect their DNA to also be similar?
Amino acid sequences are determined by the underlying DNA sequences that code for them, so similarities in amino acids suggest that the corresponding DNA sequences are also similar. Since both gorillas and humans share a common ancestor, evolutionary processes would have preserved many genetic sequences, leading to comparable DNA. Additionally, the genetic code is highly conserved, meaning that even small changes in DNA can lead to similar amino acid outputs, reinforcing the expectation of DNA similarity between the two species.
Is ammonia a mutagen?
Yes, ammonia is not classified as a mutagen. It does not directly cause changes to the DNA sequences in organisms. Ammonia is typically known for its toxic properties, mostly affecting the respiratory system when inhaled at high concentrations.
What are the changes in DNA sequences that affect genetic information known as?
Mutation
What does not read DNA sequences?
People not versed in DNA sequencing.
What do palindrome have to do with the way restriction enzymes cut DNA?
Palindrome sequences in DNA are important for the way restriction enzymes cut DNA because these enzymes recognize specific palindrome sequences and cut the DNA at specific points within these sequences. Palindrome sequences are symmetrical sequences of nucleotides that read the same forwards and backwards, allowing restriction enzymes to identify and bind to these sequences for cleavage. This specificity is crucial for the precise cutting of DNA at desired locations.
What is one way that changes occur in a DNA Sequence?
Mutations (point mutations, inversions, translocations...) cause changes in DNA Simply stated, a mistake made while DNA copies causes changes in DNA.
What similarities in DNA and protein sequences do humans and chimpanzees share?
Humans and chimpanzees share about 98.7 of their DNA sequences and have similar protein sequences due to their close evolutionary relationship.
What is the name of the substance that is used to cut DNA at particular sequences?
DNA is cut by a special kind of enzymes called restriction enzymes.
