The two polynucleotide chains in DNA molecule are attracted to each other by what?

Between nucleotides, there is a phosphodiester bond between the phosphate group of one nucleotide and the sugar of another nucleotide. Nucleotides (such as Adenine and Thymine) are held together on two strands of DNA through hydrogen bonding. This doesn't keep nucleotides together in a strand, but helps in the structure of two corresponding strands of DNA.

What organic molecule made up of a long chain of repeating units?
Many organic polymers are chains of repeating elements. These include biopolymers such as starches, glycogen, cellulose (polysaccharide chains), DNA, RNA (nucleotide chains with constant backbone but different nitrogenous bases at each position) and protein, (polypeptide chains with constant backbone but different substituent groups at each position), and other technically organic polymers such as PVC, Teflon, and Kevlar.
Are non-polar molecules more attracted to other non-polar molecules or polar molecules?
Non-polar molecules are more attracted to other non-polar molecules.
Why is the structure of a molecule important to it's function?
the structure of a molecule affects how it interacts with other molecules -apex
Where products are formed at the ribosome in a eukaryotic cell?
Polypeptides (chains of amino acids) are formed at ribosomes.These polypeptides subsequently form proteins. Some proteins have a single polypeptide chain; some have more than one. "Protein" is the term for the physiologically active molecule. After leaving the ribosome, each chain must coil and fold into the appropriate shape (and, if necessary, combine with one or more other chains) before the finished protein is formed.
Describe how phospholipid molecules are oriented in the plasma membrane of a cell?
The plasma membrane and other membranes of a cell are composed mostly of proteins and a type of lipid called phospholipids. A phospholipids molecule is structured with two fatty acids. The two fatty acids at one end (the tail) of the phospholipids are hydrophobic (not attracted to water). The other end (the head) of the molecule includes a phosphate group, which is negatively charged and hydrophilic (attracted to water). Thus, the tail end of a phospholipids is pushed away by water, while the head is attracted to water.
What is the result of mixing a water molecule and a oxygen molecule?
They are not attracted to each other because one is polar and one is nonpolar.
What is the result of mixing a water molecule and an oxygen molecule?
They are not attracted to each other because one is polar and one is nonpolar.
What is the result of mixing Water molecule with oxygen molecule?
They are not attracted to each other because one is polar and one is nonpolar.
What is the basis of an organic molecule?
Complex carbon chains and rings, with other elements "decorating" this carbon backbone.
Is the phospholipid molecule has two parts the polar end and the bipolar end?
No, you do not have that quite correct. A Phospholipid molecule has one end that is hydrophilic (is attracted to water) while the other end is hydrophobic (is repelled water but is attracted to fats).
Is a polar molecule is a molecule with the ability to resists changes in temperature?
A polar molecule is a molecule with slight opposite charges. Water is a polar molecule which means that each water molecule is attracted to other water molecules which accounts for waters surface tension or cohesion.
What term describes the attraction of one water molecule toward another?
When water is attracted to other water molecules it is called cohesion. When water is attracted to other substances it is called adhesion.
What are The forces or bonds that enable one molecule to be attracted to another molecule are called?
different bonds and forces enable molecules to be attracted to each other they include ionic bond covalent bond hydrogen bond vander waal's forces non covalent bonds
A starch molecule is like a?
Starch molecules are like chains of sugar (glucose). They can be entirely straight (amylose) or branched (amylopectin).
What is an olestra molecule?
An olestra molecule contains a sucrose molecule with fatty acids esterified onto it. In other words, sucrose (or table sugar) is chemically changed so that 6, 7, or 8 fatty acid chains are linked to it. This gives the molecule fat-like properties, but it is unable to be digested.
What type of bond attracts one water molecule to another?
When water molecules are attracted to other water molecules, this is called COHESION. This is because the oxygen end of water has a negative charge and the hydrogen end has a positive charge. The hydrogens of one water molecule are attracted to the oxygen from the other water molecules. This is what causes Cohesion. :)
Is nitrogen molecule polar or nonpolar?
diatomic nitrogen is nonpolar because neither one is attracted to the other. In other words, they both have the same electronegativity and therefore is no pull towards one in particular.
