Water’s polarity allows it to dissolve ionic and polar compounds. Because water molecules are polar, a hydrogen bond will form between the partially positive hydrogen end of one water molecule and the partially negative oxygen atom of the other water molecule.
Q. What is hydrogen bonding in water quizlet?
What is hydrogen bonding in water ? In water, the weak bond formed by the attraction of opposite charges between hydrogen and oxygen from another molecule. Hydrogen bonding help hold together many large molecules, such as proteins weak bond. You just studied 22 terms!

Q. What role does hydrogen bonding play in water?
The presence of hydrogen bonds also makes water molecules more ‘sticky’ or in scientific terms cohesive and adhesive. The small charges on the water molecules allows them to stick together which is why water has a ‘skin’ that small insects can walk on, and also explains why water can be sucked up a straw so easily.
Q. What affect does hydrogen bonding have on water quizlet?
Hydrogen bonds can form between water and other polar molecules, causing water to stick to them.
Q. Why does hydrogen bonding occur quizlet?
Hydrogen bonding occurs between molecules in which hydrogen atoms are bound to small, highly electronegative atoms.
Q. Where are hydrogen bonds found in water?
A hydrogen bond in water occurs between the hydrogen atom of one water molecule and the lone pair of electrons on an oxygen atom of a neighboring water molecule.
Q. How many hydrogen bonds can a water molecule have?
two hydrogen bonds
Q. What prevents unwound DNA from twisting?
helicase
Q. Why do hydrogen bonds allow DNA to be replicated easily?
The hydrogen bonding between complementary bases holds the two strands of DNA together. This permits the DNA strands to separate for transcription (copying DNA to RNA) and replication (copying DNA to DNA).
Q. Is RNA primer needed for leading strand?
The strand that is continuously synthesized is called the leading strand while the strand that is discontinuously synthesized is called the lagging strand. DNA synthesis requires a primer usually made of RNA. Only one primer is required for the initiation and propagation of leading strand synthesis.
Q. What is the role of RNA Primase?
Primase is an enzyme that synthesizes short RNA sequences called primers. Since primase produces RNA molecules, the enzyme is a type of RNA polymerase. Primase functions by synthesizing short RNA sequences that are complementary to a single-stranded piece of DNA, which serves as its template.
