What happens in the bonding of two nucleotides?
Phophodiester bonds are the one that connect the nucleotides next to each other on the same strand. Weak hydrogen bonds join the two complementary nucleotides and thus the two strands of the DNA together.
What type of of bonds do diatomic molecules such as h2 form?
Molecular hydrogen is bonded covalently (molecularly). Because it is composed of two atoms of just one element, their electronegativities will be the same, meaning they will attract electrons more or less equally. If this occurs, then the bond is called non-polar covalent.
Use the word biological in a sentence?
If the question is to give examples of biological in a sentence. " ...This is Biological evidence." or " Biological studies show that... "
What are some biological alternatives to chemical pesticides?
Some biological alternatives to the use of chemical pesticides is to use biological control agents like fungi, bacteria, or viruses.
What term do scholars use to refer to biological differences between man and woman?
Scholars use the term sex to refer to biological differences between men and women.
What chemicals use hydrogen bonds?
carbon nitrogen and oxygen
How do we turn hydrogen into energy we can use?
Hydrogen can be burnt with oxygen and the formation of the chemical bonds between the atoms releases energy as heat. Free hydrogen is normally manufactured by electrolysis from water, and this requires energy to separate the hydrogen-oxygen bonds, and it is this energy that is released when the chemical bonds are re-formed by combustion.
How can you use helix in a sentence?
My DNA forms a double helix due to the hydrogen bonds present in it.
What biological process does the plant need water for?
Photosynthesis is the biological process plants use to extract hydrogen from water. One hydrogen molecule is consumed to energise the process whilst the other hydrogen molecule is stored in the form of carbohydrate. Oxygen is released as a byproduct.
How the use of bonds holds the double helix together?
Generally hydrogen bonds between the different base pairs holds the double helix together.
What attracts water molecules to one another?
It is called surface tension. Somehow the water molecules are "magnetic" to each other. Hydrogen bonds are the primary intermolecular forces responsible for the unusually high cohesion forces (this is the cause behind surface tension) of water. The H-O bonds in the water molecules are highly polarized because of the large electronegativity differences between oxygen and hydrogen and there is a partial negative charge on the oxygen and a partial positive charge on the hydrogen. These partial charges are still able to attract each other and these electric attractions give rise to the high cohesion of water. Other compounds that exhibit this phenomenon of hydrogen bonding include ethanol and ammonia. Biological macromolecules also use hydrogen bonds to maintain their strucutres. For example, the two strands of DNA are held together by hydrogen bonds.
What sorts of bonds can carbon use?
Carbon atoms form covalent bonds with other carbon atoms, and with other nonmetals, such as carbon and oxygen, or carbon and hydrogen.
What types of bonds and atoms are in the molecule shown below?
Carbon, hydrogen, single bonds, and double bonds This question is easy donkey read the question before mindlessly asking, use yer brain.
How do molecules use hydrogen bonds?
Hydrogen bonds are weak electro-static forces of attraction between a highly electro-negative atom like F, O or N and Hydrogen of the same or different molecules. when a hydrogen bond is formed within a molecule, it is called Intra-molecular Hydrogen bond and when it is formed between two separate molecules, it is called inter-molecular hydrogen bond. hydrogen bond has a major role in determining various properties of a compound like the boiling point. for example, water, which is expected to be a gas at room temperature, is a liquid due to the hydrogen bonds formed between the oxygen of one water molecule and the hydrogens of the other water molecules. a water molecule can form up to 4 hydrogen bonds and so, it requires more energy to change the state of water from liquid to gas, as all the hydrogen bonds are to be broken to change its state. :)
Why humidity makes hair curly?
Hair is made up of hydrogen bonds. These can only be broken or restructured by heat or moisture. If a person with curly hair uses a flat iron they are restructuring the curl pattern (the hydrogen bonds) in effect straightening their hair. Humidity will break down those hydrogen bonds again returning the hair to it's original curl pattern. This is why when a stylist sets a persons hair, they use heat to break down the hydrogen bonds but there is always a bit of cool hair at the end to "set" that new pattern.
What is Biological cultivation?
BIOLOGICAL AGRICULTURE /BA/ is a production system which avoids or excludes the use of synthetic preparations - artificial fertilizers, esticides, growth accelerators and fodder additives.
What happens in the bonding of two nucleotides?
