who knows anything about the double helix?

As a matter of fact, I know quite a lot about genetics, what specific info about it are you asking for?
 
haha enigma, I am actually studying for my bio exam right now
4 types of nucleic acids
adensine
cytokine
guanine
thymine

the pairings of these chemicals are
A-T, T-A, C-G, G-C
 
exactly, and DNA determines the sequence and order of amino acids, which make up proteins, which is very essential for growth (building, repairing and maintainence)
 
Which are one of the four basic molecules of biochemistry. The others are carbohydrates, lipids, and amino acids
 
that is correct, and if I may suggest, DNA is one of the four MACROMOLECULES, and the rest are carbohydrates, lipids, and proteins (which are macromolecules made up of amino acids)

carbohydrates are made up of sugar units and they MUST have carbon, hydrogen, and oxygen, their chemical formula is usually C(subscript n)H (subscript 2n)O (subscript n), for instance, glucose is C6H12O6, and there are three kinds of carbohydrates: monosacchrides, disacchrides, and polysacchrides
 
No, DNA is not a macrolecule, but nucleic acids are, and they make up both DNA and RNA. I messed up when I said amino acid.

sugars usually end in "cose"
enzymes end with "ase"
 
sorry that's what I meant, nucleic acids are macromolecules, and others are carbohydrates, protein and lipids

actually no sugars usually end with "-ose"
for instance: glucose, fructose, lactose, maltose, sucrose

and carbohydrates are the most important source of energy for humans
 
Thanks for corecting me with the sugar thing.

Glycogen is how carbs are stored for short term use and is converted into lactic acid in animals, and a form of alcohol is plant. Lipids are used for long- term energy storage.
 
no problem

plants store their glucose in form of starch, and when they need it, they break the starch molecules down with amylase, a digestive enzyme also found in the saliva
 
haha thank you:)

my bio exam is on thursday, so I have been studying for it since last week, wish me luck:D
 
thank you, wow I am in grade 10, but I am taking grade 11 biology, it's actually quite hard, we do cellular functions, genetics, internal systems, plants, and microbes
genetics and internal systems are my favourite
