Mutations (point mutations, inversions, translocations...) cause changes in DNA
Simply stated, a mistake made while DNA copies causes changes in DNA.
What else can I help you with?
What is one way that changes can occur in a DNA sequence?
A radioactive carbon isotope can "convert" ... changing the chemistry of a codon.
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 is one way for a mutation to occur to a DNA molecule?
It's when plants see sun light
How do you know if you are looking at a DNA or RNA sequence?
DNA sequences contain the nitrogen bases adenine, thymine, cytosine, and guanine. RNA sequences contain the nitrogen bases adenine, uracil, cytosine, and guanine. If the sequence contains thymine it is a DNA sequence if it contains uracil it is an RNA sequence.
Gene cloning is an efficient way to produce many copies of a specific DNA sequence?
Yes, gene cloning involves inserting a specific DNA sequence into a vector, such as a plasmid, to produce multiple copies of that DNA sequence. This can be useful for producing large amounts of a particular gene for further research or application.
What 2 ways can DNA change?
DNA can change through mutations, which are alterations in the nucleotide sequence, and can occur due to errors during DNA replication or from environmental factors like radiation or chemicals. Another way DNA can change is through recombination, which involves the exchange of genetic material between different DNA molecules, often seen during sexual reproduction. Both processes contribute to genetic diversity and evolution.
Why prokaryote dna circular?
I am really not sure about the causality here - that is whether the following are answers to your question, or are merely results of the circular DNA structure. One possible answer is that this way the DNA has no telomere sequence and therefore the Haylfick limit does not apply - they can keep on dividing indefinitely. Also, the rolling cirlce replication of the DNA (which can only occur in a circular molecule) is a simpler mechanism than in eukaryotes. Sexual processes of bacteria, such as conjugation, also depend on the rolling-cirlce, mentioned above.
What is GAATTC?
It is a sequence of DNA that is also a palindrom. i.e. the complimentary sequence of DNA would read the same way (but in the other direction). g a a t t c c t t a a g Moreover it is the sequence of DNA recognised by the restriction endonuclease EcoR1, the first such enzyme to be discovered. These enzymes have been important tools in science allowing pieces of DNA to be specifically excised and manipulated.
Which best describes how scientists found he human gene that makes insulin?
they worked backwards from mRNA to DNA Ap#x
When does a reading frame shift occur?
A reading frame shift occurs when nucleotides are inserted or deleted from a DNA or mRNA sequence, causing a shift in the way the sequence is interpreted by the ribosome during translation. This can result in a completely different amino acid sequence being produced, leading to a non-functional or altered protein.
What is the name of the circular DNA found in a prokaryote?

During DNA replication which sequence of nucleotides will bond to the sequence ACGTAT?
The RNA base sequence will be CGAUUAGGCThis answer assumes that the DNA sequence in the question is the sequence on the template strand.The way to work it out is to take the complementary base of each base in the DNA:the complement of G is Cthe complement of C is Gthe complement of A is U in RNA (T in DNA)the complement of T is AAnswer is actually (E) ATACA because if you use TATGA and do the complement, which is a=t and c=g
