What is the function of DNA?
is the atom that carries genetic information for the development and functioning of an organism
is the molecule that carries genetic information for the development and functioning of an organism
is the cell that carries genetic information to the brain
is the molecule that carries genetic information to the brain
Each nucleotide contains three/four components:
a phosphate group, which is one phosphorus atom bonded to four oxygen atoms, a sugar molecule, and a nitrogen base.
a phosphate group, which is two phosphorus atoms bonded to four oxygen atoms, a sugar molecule, and a nitrogen base.
2 phosphate group, which is one phosphorus atom bonded to four oxygen atoms, a sugar molecule, and a nitrogen base.
a phosphate group, which is one phosphorus atom bonded to three oxygen atoms, a sugar molecule, and a nitrogen base.
The four types of nitrogen bases are arranged as...
Thimine with Guanine, and Citosine with Adenine
Adenine with Cytosine, and Guanine with Thymine
Adenine with Thymine, and Guanine with Cytosine
