What is the purpose of replication?
DNA replication is the means of producing two identical replicas from one original DNA molecule. This is the basis for biological inheritance.
Why transcription is unidirectional?
Transcription is unidirectional because you are copying only ONE side of the DNA. Remember that DNA is a double stranded helical structure. One strand of DNA is complementary to the other strand.
What types of vectors are used to carry DNA from one species into the DNA of another species?
There is a structure called a plasmid which can do this; it is bacterial in origin.
Which organelle or cell structure would you expect to contain the most radioactivity after a DNA Synthesis?
That one The structure that would contain the most radioactivity would be chromosomes, because chromosomes are made up of DNA.
Carbon ring structure of DNA and RNA that contains one or more atoms of nitrogen?
Carbon ring structures found in DNA or RNA that contains one or more atoms of nitrogen are called nitrogenous bases. There are five types of nitrogenous bases: Adenine, Thymine, Cytosine, Guanine and Uracil
What letters A B C G does not represent one of the possable basis in the DNA structure?
The letter B does not represent one of the possible basis in the DNA stucture. The letters A represent Adenine, G represent Guanine , C represent Cytosine and the 4th is T for Thymine.
What describes the structure formed wjen a probe hybridizes to a gene?
A double-stranded DNA structure in which one strand is the probe.
Does cytosine contain a purine?
DNA does in fact contain cytosine. This is one of the 4 nucleic acids that are found inside of DNA.
Do stem cells contain DNA?
DNA is traced to and found in all cells including stem cells.
What was the methods Watson and crick used to determine the structure of DNA?
One of the main things they looked at the the x-ray crystallography photograph completed by Rosalind Franklin. Using this they found DNA to be a double helix.
How does DNA store information in code?
the structure of DNA allows DNA to contain information.The order of the bases on one side of DNA is a code that carries information
Is adeninefound in DNA?
Yes. Adenine (A) is one of the nucleotides found in DNA
What the letters does NOT represent one of the possible bases in the DNA structure?
g
What describes the structure form when a probe hybridizes to a gene?
A double-stranded DNA structure in which one strand is the probe.
What describes the structure formed when a probe hybridizes to a gene?
A double-stranded DNA structure in which one strand is the probe.
What is the purpose of replication?
DNA replication is the means of producing two identical replicas from one original DNA molecule. This is the basis for biological inheritance.
Is DNA found in the nucleus mitochondria and chloroplasts?
in which one of the following DNA is not found? (a)peroxisome (b)nucleus (c)chloroplast
