Chewing on a pencil may leave saliva containing cells from the mouth, but it is highly unlikely to leave DNA that can be easily extracted and analyzed. Pencils are not designed to retain DNA samples like Chewing Gum or other items might.

Why did you use RNA instead of DNA to make proteins?
RNA is used to make proteins because it serves as the intermediary molecule between DNA and proteins in the process of protein synthesis. DNA holds the genetic information, but it remains in the nucleus, so RNA is needed to carry this genetic information to the ribosomes where proteins are synthesized. RNA is more versatile and mobile than DNA, making it ideal for this role.
What strand of DNA would be prod from the template strand of DNA shown below?
The complementary strand of DNA to the template strand TACGGCTA would be ATGCCGAT.
Why cant DNA leave the nucleus?
DNA is too large to pass through the nuclear membrane pores. Additionally, DNA is complex and needs to be protected from potential damage or interference. By staying in the nucleus, DNA can be safely stored and maintained for proper replication and transcription processes to occur.
What complementary strand of DNA would be produced from the DNA strand cgt ta?
The complementary strand of DNA to cgtta would be gcaat. This is because in DNA, cytosine pairs with guanine and thymine pairs with adenine.
Which organelle or cell structure would you expect to contain the most radioactivity after a DNA Synthesis?
The nucleus would contain the most radioactivity after DNA synthesis, as this is where DNA replication takes place. The newly synthesized DNA would thus be housed in the nucleus, making it the organelle most likely to be radioactively labeled.
Does chewing tobacco give a false DNA test?
Chewing tobacco can potentially affect the result of a DNA test by contaminating the sample with DNA from the tobacco residue. This could lead to inaccurate results or difficulties in interpreting the test. It is recommended to avoid using tobacco products before providing a DNA sample.
Can you get a falls DNA test from chewing tobacco?
It's false and no.
What are the 3 models of DNA replication?
Conservative replication would leave intact the original DNA molecule and generate a completely new molecule.Dispersive replication would produce two DNA molecules with sections of both old and new DNA interspersed along each strand.Semiconservative replication would produce molecules with both old and new DNA, but each molecule would be composed of one old strand and one new one.
Which one can leave the nucleus: DNA or RNA?
RNA can leave the Nucleus.
What evidence might kidnapped children leave behind that would contain their DNA?
Kidnapped children may leave behind items such as clothing, personal belongings, and hair strands that could contain their DNA. Additionally, skin cells, saliva, or blood traces on objects or surfaces at the scene could be sources of their DNA. DNA analysis of these samples can help identify the child and aid in investigations.
Could DNA come off with soap and water?
There is DNA in most cells in your body, so you could leave some DNA behind after washing.
How does mRNA leave the the nucleus after copying DNA?
nucleic acids
How would the DNA of the human compare to the DNA of the duck?
DNA is DNA it can not be changed.
Does rubber gloves leave DNA?
Not likely. If a skin cell from your hand were to fall off and through the glove DNA could be left. Hair is also a source for DNA.
How would prevention of DNA synthesis affect mitosis?
There would not be enough DNA to put in daughter cells, since DNA synthesis is the replication of DNA.
What would happen to an organism that lost or never had the ability to replicate its DNA?
An organism that lost the ability to replicate its DNA would be unable to reproduce and pass on its genetic material to offspring, leading to its eventual extinction. If an organism never had the ability to replicate its DNA, it would not be able to grow, develop, or carry out essential biological functions necessary for survival.
What can leave the nucleus but DNA cannot?
Because mRNA is a single stranded molecule where as DNA forms a double helix. Therefore mRNA is a smaller molecule than DNA so can leave the nucleus ALSO mRNA has been processed post-translation. This means a 5' cap has been added and a 3' poly(A) tail has been added. This 5' cap, which DNA does not have, allows mRNA to leave the nucleus through nuclear pores. All above is good idea all , And me have something that need to include more. First time DNA can't leave from nucleus ,so DNA change to be nucleotide then mRNA go into nucleus and duplication ,A , T, C, G of DNA to be U,A,G,C. During mRNA get out from nucleus , mRNA will go to ribosomes to produce protein to take care cell.
