In DNA what does adenine always pair up with?
In DNA replication, adenine binds with thymine. In RNA, adenine binds with uracil.
What are the rules governing DNA bonding?
A binds with T and C binds with G
3 DNA does NOT contain the nitrogen base?
DNA does not contain uracil. RNA does!! DNA contains guanine binds with Thymine in DNA RNA contains guanine that binds with uracil DNA does not contain uracil. RNA does!! DNA contains guanine binds with Thymine in DNA RNA contains guanine that binds with uracil
What attaches free nucleotides to the growing DNA strand?
During DNA replication, DNA polymerase binds free DNA nucleotides to an unzipped DNA strand. During transcription, RNA polymerase binds free RNA nucleotides to the unzipped anti-sense DNA strand.
What group makes up the rungs or steps of DNA?
The "rungs" of DNA are the nitrogenous bases (Adenine, Thymine, Cytosine and Guanine). To make the rungs - A binds to T and C binds to G.
How is complementary base pairing different when pairing DNA to DNA than DNA to mRNA?
When pairing DNA to DNA - A binds to T and C binds to G. However, in RNA, the T is replaced with U. Therefore when DNA pairs with mRNA - A binds to U, C binds to G and T binds to A.
What region of the DNA does the giemsa stain dye?
Giemsa stain binds the regions with high content of adenine-thymine complex.
What is the order of actions by rna polymerase?
Binds to DNA, makes mRNA from DNA, detaches
During protein synthesis in eukaryotic cells does the activator-enhancer complex the molocule of DNA so other transcription factors have better acces tothe bonding sites on the operator?
Yes. If I understand your question correctly (I cleaned up the wording slightly). Activators are proteins that bind to enhancer regions of DNA. This facilitates the binding of transcription factors and the RNA Polymerase to read the DNA of the gene.
Where is dna located in a eukaryote cell?
in the nucleus
In DNA what does adenine always pair up with?
In DNA replication, adenine binds with thymine. In RNA, adenine binds with uracil.
What are the rules governing DNA bonding?
A binds with T and C binds with G
What is the mRNA for DNA molecule t-a-c- c- g -g?
If a DNA strand read CCTAGCT, its mRNA would read GGAUCGA.
What molecules are found in a DNA nucleotide?
Guanine which binds with Cytosine, and Adenine which binds with Thymine.
In a single strand of dna the phosphate group binds to what?
It binds to a Deoxyribose sugar. Thus, the structure of DNA is Phosphate-Deoxyribose-Nitrogenous Base.
What Nucleotides pairs are found in a DNA molecule?
Guanine which binds with Cytosine, and Adenine which binds with Thymine.
In eukaryotes the interaction of enhancer and promoter elements is brought closer by?
DNA looping
