What else can I help you with?
DNA computers have the potential to take computing to new levels which of the following is not an advantage of using DNA instead of silicon?
Today's computers are many times smaller than DNA computers.
What is the National DNA Index System?
It's a government agency which holds the DNA 'fingerprint' of every arrested person (since the database came 'live') in your country.
Which career combines DNA technology and forensics?
Genetics.
What is the final product of recombinant DNA technology?
Typically a protein.
How can cloning technology be used?
Cloning is done to copy and learn the DNA.
Which of these statements does not describe introns?
Non-expressed
Which of the following statements about okazaki fragment in e coli is true?
They are formed on the lagging strand of DNA.
Which of the following statements regarding cDNA libraries is false?
a. They are usually double stranded DNA. b. They are composed of DNA synthesized with the use of reverse transcriptase. c. They are composed of DNA synthesized from an mRNA template. d. They contain introns and exons. e. They contain DNA that is complementary to the mRNA from which it was synthesized.
Describe how each of the DNA nitrogen bases together in DNA?
Describe how each of the DNA nitrogen bases pair together
Which of the following statements correctly describes the timing of DNA synthesis?
DNA is synthesized in the S phase of interphase.
How would protein synthesis be affected if DNA was not replicate accurately?
d
What term is used to describe the the process of copying DNA?
Replication is the term used to describe the process of copying DNA. Or perhaps transcription.
True or false the term bloodline accurately describes heredity because DNA is carried to offspring through the mothers blood?
False. The term bloodline does not accurately describe heredity because DNA is passed down from both parents to offspring through their genetic material (sperm and egg), not through the mother's blood. Blood does not carry genetic information in the sense of passing on hereditary traits.
What is the change in the sequence of bases in a DNA molecule most accurately referred to as?
The change in the sequence of bases in a DNA molecule is most accurately referred to as a mutation. Mutations can occur due to errors in DNA replication, exposure to certain environmental factors, or as a result of genetic inheritance.
How is the nitrogenous base numbering system used in molecular biology to identify and characterize DNA sequences?
The nitrogenous base numbering system in molecular biology is used to identify and characterize DNA sequences by assigning a specific number to each base in the sequence. This numbering system helps scientists accurately describe the order and composition of the bases in a DNA molecule, which is crucial for understanding genetic information and conducting research on DNA.
How is the DNA able to re associate accurately when it is lowered at room temperature greater than 85 degrees celsius?
DNA re-associates accurately after being denatured at high temperatures because it has complementary base pairing, meaning adenine pairs with thymine and guanine pairs with cytosine. When the DNA is cooled down, the complementary bases rejoin, allowing the DNA strands to reassociate accurately. Additionally, the cooling process allows the hydrogen bonds between the base pairs to reform, stabilizing the double helix structure of DNA.
What factors is most likely caused a mutation in DNA?
There are two main factors that cause a mutation in DNA. These factors include: the DNA fails to accurately copy itself and external influence cause a breakdown in the DNA.
