how many hydrogen bonds form between a and t in a molecule of DNA

how many hydrogen bonds form between c and g in a molecule of DNA

Which sugar and nitrogenous bases do RNA nucleotides contain

what is a single-stranded molecule made up of one polynucleotide strand

What are the similarities between DNA and RNA

what refers to the fact that each of the newly synthesised DNA molecules is made up of one original DNA strand and one new DNA strand

what breaks hydrogen bonds between complementary bases to unwind the double helix and separate the strands

what joins nucleotides together via phosphodiester bonds

What reaction takes place to join nucleotides together during semi-conservative DNA replication

What does ATP stand for

What 3 parts does a molecule of ATP consist of

What are some uses of ATP in the body

How does ATP activate other molecules

What is released during the condensation reaction to reform ATP

What enzyme catalyses the resynthesis of ATP

What enzyme catalyses the hydrolysis of ATP

What are the products of ATP hydrolysis

How is ATP broken down

in a water molecule, the oxygen atom has a slightly negative charge whilst the hydrogen atoms have a slightly positive charge so the water is

what is the attraction between the partially positive hydrogen end of one water molecule and the partially negative oxygen end of another water molecule

What are the roles of water in living organisms

Water is known as the _________ because it dissolves more substances than any other liquid.

Water being a ______ is useful as most biological reactions take place in solution and so dissolved substances can be transported around the body

what is it when a lot of energy is required to raise the temperature of water

what is it when a lot of energy is needed to break the hydrogen bonds to change water from a liquid to a gas

^why is this important for organisms

Why is water a suitable habitat for many organisms

what is the tendency of water molecules to stick together

what is the tendency of water to stick to other materials

what allows water to flow through organisms, carrying substances along with it
