Protein Basics
• Proteins are made up of carbon, hydrogen, oxygen, and nitrogen
• These elements are joined into strands called Amino acids
• Proteins do many important jobs such as cellular repairs, growth, and helping the human body work
• It is the main structural molecule in the human body

The Building Blocks Of ProteinThe Building Blocks Of Protein
• Proteins are made up of Amino Acids which form long chains called polypeptides
• The arrangement of the Acids affects the chemical composition of the proteins
• There are 20 different amino acids found in nature
• All amino acids are exactly the same where they can be joined in Covalent bonds
• Because of this any amino acid can be joined to another amino acid
• Proteins are made up of Amino Acids which form long chains called polypeptides
• The arrangement of the Acids affects the chemical composition of the proteins
• There are 20 different amino acids found in nature
• All amino acids are exactly the same where they can be joined in Covalent bonds
• Because of this any amino acid can be joined to another amino acid

The Hungry Proteins
• Some proteins are enzymes
• Proteins all have a specific complex shape
• Because of that substrates (the reactants of an enzyme catalyzed reactions) bind into a active site on the enzyme perfectly
• This is referred to as a lock and key
• They remain bound together until the reaction is done

DNA & RNA Basics• DNA is made up of Nucleotides • Nucleotides are made up of three parts: a deoxyribose
molecule, a phosphate group, and a nitrogenous base.• There are 4 different bases in DNA: adenine, guanine,
cytosine, and thymine• RNA is also made up of Nucleotides but there are some
differences • RNA sort of like a disposable copy of DNA • RNA can be used for many different things but they are
mainly used for producing protien• Both carry genetic information, can carry proteins, and
can make copies of themselves
![Page 6: Standard 8 By: Andrew & LaBarron. Protein Basics Proteins are made up of carbon, hydrogen, oxygen, and nitrogen These elements are joined into strands.](https://reader034.fdocuments.in/reader034/viewer/2022042822/56649e585503460f94b522db/html5/thumbnails/6.jpg)
DNA vs RNA• RNA is like DNA except for three things
1.The sugar in RNA is a ribosome is a ribose instead of deoxyribose
2.RNA is generally single-stranded
3.RNA contains uracil in place of thymine
4.It also can transport Amino Acids

Pairing of DNA & RNA• DNA bases Adenine (A), Thymine
(T), Cytosine (C), Guanine (G) • In RNA though they have Uralic
(U) instead of Thymine• In the DNA Double Helix
T and A and G and C connect together and when RNA comes off DNA T gets replace with U
• When DNA replicates then the order of the bases is mirror image
• Instead of AGTC it would be TCAG

DNA and Your Genes and Chromosomes
• Chromosomes are made up of DNA
• The chromosomes are wrapped around proteins called histones that are bundled together
• Things inside chromosomes are called genes
