Enzymes
- Definition
of an Enzyme
- This is just a strict definition of an enzyme and related
terms.
- What
the Heck is an Enzyme?
- Much like the entire "Bugs in the News" series, this site
is written in a conversational, easy to understand manner. It's
main focus is on chemical reactions.
- What are
Enzymes?
- An extensive, easy to understand discussion of the
properties of enzymes.
- Enzymes
- Another easy to understand description which includes a
recap of main points at the end of the essay.
- Introduction
to Enzymes
- Includes many topics such as What are Enzymes, Why Study
Enzymes, Properties of Enzymes, and How Do Enzymes Work.
- Enzymes:
Biological Catalysts
- This is a more advanced outline of the function of enzymes.
It includes some diagrams of chemical structure.
Proteins
Amino Acids
Sickle Cell Anemia
Ribonucleic Acid (RNA)
- RNA
Page
- This site is primarily for researchers, so it is a very
technical site. But it has neat images to peruse.
- The RNA
World
- Here you can find world-wide links to RNA related topics.
But again the page is designed for researchers.
- Properties
of the three major RNA species
- A nice site which gives a brief outline of information on
transfer RNA, ribosomal RNA, messenger RNA, and RNA synthesis.
- Aminoacyl-tRNA
synthetases
- Visit this site for the great images.
Viruses
Francis H. C. Crick
Genetic Code
- The
Genetic Code
- In this module we will examine the origin and implications
of the genetic code. In the first section we will look at
selected experiments that lead to the cracking of the code that
relates the language of nucleic acid with the language of
protein. In the second section we will look at how mutations
affect the final product of translation.
- Table
of Standard Genetic Code
- This is a nicely designed site - it's easy to use the
table.
- PPS
96' - The Genetic Code
- The table is not as easy to use, but it has good
information on wobble bases and reading frames.
- Greg
Stuart's Standard Genetic Code
- This site has a nice table, but even better it has links to
information and diagrams of each amino acid.
Central Dogma
Transcription
- From
DNA to RNA
- This is a fun site. Just to give you a taste: "Imagine you
are a cook... You want to make a nice dish. You take a receipe
book. The receipe in the book is very long, with a lot of
pictures and useless things, and you don't want to damage the
book by using it in the kitchen."
- Elements
of Transcription
- The elements of transcription include: DNA, RNA, rRNA,
tRNA, mRNA, RNA polymerase, gene structure, transcription, and
the regulation of genes.
- Transcription
of DNA to Messenger RNA
- A nice flow chart from Access Excellence.
- Unraveling
the genetic code
- A news story about research on transcription.
Translation
- BioTech:
An Introduction to Translation
- This page is written mainly for people who have little or
no knowledge of translation. (It's a good introduction.)
- Protein
Synthesis - Translation
- More complete than the above site, this page gives an
overview of translation followed by a discussion of amino acid
activation and the mechanism of protein synthesis.
- Slides
- This is an excellent site which steps you through the
entire mechanism using a series of colorful slides.
Recommended!
- Animation
- Here the slides were made into an animation. Excellent if
you can download it!
- Cinemation
- (This file must be converted with BinHex 4.0 if you have
it)
