it is called ahomonuclear diatomic molecule, such as oxygen (O2) and nitrogen (N2).Polyatomic moleculeshave more than two atoms, such as water (H2O) and carbon dioxide (CO2
DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and anitrogenbase. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytos...
What is DNA made of? DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (...
What does DNA stand for and what are the four bases of DNA? What base is NOT normally found in a DNA molecule? What are the repeating subunits called that make up DNA? What forms does DNA come in? A) E-DNA and F-DNA B) B-DNA and G-DNA C) P-DNA and O-DNA D) A-DNA and...
Nucleic acids are the molecules that contain and help express a cell's genetic code. There are two major classes of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the molecule that contains all of the information required to build and maintain the cell; RNA ha...
Cells come in many different varieties, with many different functions, but inside, almost every cell is a nucleus, containing 99.9% of your genes, and mitochondria, containing a few more genes. All told, you’ve nearly 20,000 genes, your genes are small parts of a long molecule, called ...
this, a DNA molecule is cut into smaller pieces and then used as a template for a particular strand of RNA that has been copied from the DNA’s matching complementary strand. This RNA is then able to match up with each piece of DNA and can be read off slowly, one letter at a time...
The Double Helix of DNA DNA stands for deoxyribonucleic acid, a molecule that consists of two long, intertwined polymers forming a structure known as a double helix. A polymer is a long molecule made of many identical, or similar, subunits. Deoxyribonucleotide: Subunit of DNA ( Interactive ...
In the glycolytic pathway, one glucose molecule is broken down, and during the reaction, two ATP molecules are generated. The reaction can be represented as:C6H12O6 + 2 NAD+ + 2 ADP + 2 H3PO4 → 2 NADH + 2 C3H4O3 + 2 ATP + 2 H2O + 2 H+ Citric Acid Cycle In mitochondria, ...
