The 4 nitrogenous bases are:
Adenine, Cytosine, Thymine, Guanine
RNA has the base uracil that DNA does not have.
RNA has the base uracil that DNA does not have.
The mRNA sequence generated from the DNA strand tgacgca would be acugcgu. This is because mRNA is complementary to the DNA template strand, so DNA base T pairs with mRNA base A, DNA base G pairs with mRNA base C, DNA base A pairs with mRNA base U, and DNA base C pairs with mRNA base G.
RNA has the base uracil which replaces the thymine base of DNA.
TACA
RNA has the base uracil which replaces the thymine base of DNA.
Thymine
Exocytozine
The nitrogen base thymine in DNA is replaced by the nitrogen base uracil in RNA.
DNA is deoxyribonucleic acid why DNA is called acid but it contains nitrogenous base.
It is not a DNA base pair itself, it is a DNA nucleotide base. It does however, form a base pair when bonded with adenine.
Guanine is a complementary base for cytosine in DNA.
