Why might a laboratory be using dideoxy nucleotides?
A laboratory might be using dideoxy nucleotides in DNA sequencing reactions, specifically in the Sanger method. Dideoxy nucleotides lack a 3’ hydroxyl group needed for DNA chain elongation, resulting in termination of DNA synthesis at specific bases. This allows for the determination of the nucleotide sequence of a DNA fragment.
what is a technique to determine the order of nucleotide bases in a fragment of DNA?
One common technique to determine the order of nucleotide bases in a DNA fragment is Sanger sequencing, also known as chain termination sequencing. This method involves using a DNA polymerase to replicate the DNA while incorporating labeled dideoxynucleotides, which terminate the elongation process. The resulting fragments are then separated by size using capillary electrophoresis, allowing the sequence to be read based on the terminal labeled nucleotides. This technique provides accurate sequence information for relatively short DNA fragments.
How many bases does DNA consist of?
There are four types of bases in DNA: adenine, cytosine, guanine, and thymine. However, a molecule of DNA may be a polymer of millions of these bases in a specific arrangment.
Have many nitrogen bases does the DNA of a bacteria have?
Bacterial DNA has four nitrogen bases; adenine, guanine, cytosine, and thymine.
What are the DNA fragments produced by automated DNA sequencing are identified using what?
DNA fragments produced by automated DNA sequencing are identified using fluorescent dyes or radioisotopes attached to the nucleotides in the DNA sequence. The sequencing machine reads the colors emitted by the dyes or the radioactive signals to determine the order of bases in the DNA fragment.
What are the four ingredients added to a test tube to produce tagged DNA fragment that can be used to read a sequence of DNA?
The four nucleotide bases A, T, G, and C.

How many DNA bases are present in 8 DNA nucleotides?
There are 32 DNA bases in 8 DNA nucleotides.
How many bases are in DNA and what are the names of the bases?
There are 4 bases in DNA: adenine, thymine, cytosine, and guanine.

Which fragment of DNA is the longest or biggest?
The fragment of the DNA that is the longest is the one that is the slowest to get to the bottom of the gel in the body. This is because longer DNA are simply the largest base pairs that are digested in the restriction enzymes which make them slower then the shorter ones.

DNA fragments produced by automated DNA sequencing are identified using fluorescent dyes or radioisotopes attached to the nucleotides in the DNA sequence. The sequencing machine reads the colors emitted by the dyes or the radioactive signals to determine the order of bases in the DNA fragment.
What is maxam Gilbert method of DNA packaging?
Used in DNA sequencing; four samples of end-labeled DNA restriction fragments are chemically cleaved at different specific nucleotides. The resulting subfragments are separated by gel electrophoresis, and the labeled fragments are detected by autoradiography. The sequence of the original end-labeled restriction fragment can be determined directly from parallel electropherograms of the four samples
How many bases are in one cell's DNA?
5.5
An okazaki fragment has which of the following arrangements?
An Okazaki fragment is a short, newly synthesized DNA fragment that is formed on the lagging strand during DNA replication. It is composed of a short RNA primer at the 5' end and DNA nucleotides that extend toward the replication fork.
