What else can I help you with?
Does serum contain DNA?
Serum is generally free from blood cellular components but when collecting serum sometimes few cells will be pipetted with the serum & that is the only source of DNA in the serum.
What end of a growing strand are DNA nucleotides added to?
5' end (nucleotides are added from 3' toward 5')
What part of a DNA molecule is responsible for the genetic code?
The genes present in a DNA molecule are responsible for the genetic code. Within the genes, the exons specifically are the coding regions.
The correct order of steps in doing genetic engineering is?
The steps are: 1. Cutting DNA 2. Making recombinant DNA 3.Cloning 4. Screening
What are the steps of using recombinant DNA technology?
1 Isolate DNA 2 Cut DNA with a restriction enzyme 3 Mix the DNA's and join then together by using DNA ligase 4 Insert the recombinant plasmid into a host bacterium 5 Allow the bacterium to reproduce
What are 3 components of the DNA?
A 5-carbon sugar, a phosphate, and a nitrogenous base.
What are the 3 major groups of chemicals in DNA?
What are the 3 major groups of chemicals in DNA? DNA is made up of three basic chemical components: Phosphate. Deoxyribose (a sugar). Two Pyrimidines Cytosine and Thymine. Two Purines Guanine and Adenine.
What enables cellular components to copy themselves independent of DNA?
Replication enables cellular components to copy themselves independent of DNA.
What are the three components of DNA polymer?
The three components of DNA polymerase are a polymerase domain responsible for synthesizing new DNA strands, a proofreading domain for error correction, and a domain that binds to the DNA template strand.
Describe the components of the replication machine.?
The main components of a replication machine include DNA helicase, which unwinds the DNA double helix; DNA polymerase, which adds new nucleotides to the growing DNA strand; primase, which synthesizes RNA primers for DNA replication to start; and DNA ligase, which joins the Okazaki fragments on the lagging strand. These components work together to ensure accurate and efficient replication of DNA.
Which components of DNA make up the outsides of the DNA ladder?
sugar and phosphate.
What are 3 components of the DNA nucleotide?
The three components that create a DNA nucleotide are a phosphate group, a nitrogenous base [this will be either Adenine, Guanine, Cytosine, or Thymine], and a Sugar [deoxyribose, which is how we get the D in DNA].
What components are present in DNA but not RNA?
thymine
What type of DNA are holding the molecule together?
What components make up the backbone of DNA
What is the name of DNA subunit?
deoxyribose, phosphate, guanine, tyrosine, adenine, and cytosine are the components of DNA
Components of DNA and its location in the cell?
Nucleus of the cell
How many components make up one nucleotide of DNA?
A nucleotide of DNA is composed of three main components: a phosphate group, a five-carbon sugar molecule (deoxyribose), and a nitrogenous base (which can be adenine, thymine, cytosine, or guanine). These components work together to form the building blocks of DNA, linking together to create the DNA strand.
