It doesn't contain an OHO bond so no other nucleotides can attach to it.

How a change in the sequence of nucleotides in a strand of DNA might cause a protein to malfunction?
The sequence of nucleotides is altered and therefore, the amino acid that is to be added to the peptide chain will be altered. hence the protein will be different. This protein can be functionless (will be degraded). If it turns out to be toxic, then there may be symptoms.
2 disorders caused by DNA sequencing?
DNA sequencing is an analytical method used in the laboratory to find out the sequence of nucleotides on a strand (or chain) of DNA. It does not cause any disorders. What causes disorders are mutations, which are unregulated changes in the DNA sequence that happen within the body
The DNA of all living organisms is composed of the same nucleotides It is only the sequence of nucleotides and quantity of DNA an organism possesses that cause the differences between organisms?
True
Why does a Cytosine-Adenine rich strand degrade?
A Cytosine-Adenine rich strand may degrade due to several reasons. One possibility is the hydrolysis of the phosphodiester bonds in the DNA backbone, which can lead to strand breakage. Additionally, certain environmental factors or enzymatic activities may cause the destabilization of the DNA structure, making it more susceptible to degradation. Finally, the presence of specific damaging agents, such as radiation or reactive oxygen species, can also contribute to the degradation of a Cytosine-Adenine rich DNA strand.
How can you find the mRNA strand out of a DNA strand?
First, you must understand that a strand of mRNA, is the complement of one side (the left) of DNA. Basically, you take the one side of the DNA strand and complement it by using these pairs: Adenine:Uracil, Cytosine:Guanine, Thymine:Adenine. They are all usually abbreviated by their first letter. Second, in order to find the mRNA, you must understand the process of protein synthesis. If you know the process, then it should be clear that the mRNA is made from one side of the DNA strand during the transcription. It then moves out of the cell and into the cytoplasm to start translation.
How do nucleotides cause living things to differ from on another?
the reason is that each living thing has a different order of nucleotides in its DNA

Why are there many replication forks?
A replication fork is the mechanism by which a strand of DNA is synthesized. If you can imagine a strand of DNA unwound, then it would resemble a ladder. Unzip the DNA and it now looks like a fork, ie fork in road, not eating fork. There is a Leading strand, which is synthesised easily. USing DNA polymerase which 'reads' along the strand in the 3' to 5' direction on the strand, producing a replication strand in the 5' to 3' direction. The opposite strand is called the lagging strand, and this is slightly more complicated. DNA polymerase cannot read in the 5' to 3' direction on the template strand. Thus DNA primase is used to read the strand and replicate small RNA segments, called Okazaki fragments. The lagging strand has no been copied into many small strands of RNA, or Okazaki fragments. Next DNA polymerase comes along and replaces all the RNA nucleotides with DNA nucleotides. ANd finally DNA ligase 'stitches' all the small fragments into one long strand.
The DNA of all living organisms is composed of the same nucleotides It is only the sequence of nucleotides and quantity of DNA an organism possesses that cause the differences between organisms?
True
What happens when you swallow human hair?
Swallowing the occasional strand won't cause a thing.
How many nucleotides would cause a frame shift mutation?
Adding or subtracting just one nucleotide would cause a frame shift mutation.
How does an insertion sequence cause a mutation?
In the DNA, the sequence of nucleotides determines how proteins are built, with each segment of three nucleotides encoding a single amino acid. When one nucleotide is inserted into the sequence, the whole sequence shifts, and all the triples are changed completely, which can cause detrimental mutations.
What is proto-oncogen?
An oncogene is a modified gene, or a set of nucleotides that codes for a protein and is believed to cause cancer.
What is the smallest number of nucleotides that must be added or subtracted to cause a frame- shift in the triplet grouping of the genetic message?
1
Can hepatitis C cause a cocaine positive hair strand result?
taking Pedigron injects for 6 months weekly for cronic hepatitis C tested positive hair strand result for cocaine
The insertion of how many nucleotides into a genetic sequence does less damage to the code than the insertion of other numbers of nucleotides?
3 cause 3 nts corresponding to an amino acid so it wont effect all the following code after insertion
