The stop codons
What are UAA, UAG, UGA?
300
A DNA molecule has the same amount of adenine as thymine and of cytosine as guanine. A=T, C=G
What is Chargaff's rule?
300
The ribosome subunit attaches to the 5' end of the mRNA molecule. The first codon there is always AUG.
What is the first step of translation?
300
Brings the correct DNA nucleotides for replication
What is DNA polymerase?
300
Adenine and Guanine
What are the purine bases?
300
Small pieces of DNA created by backwards movement for short intervals. These are linked together by DNA ligase.

400
Cytosine and thymine
What are the pyridimine bases?

DNA codes for RNA, which guides the synthesis of proteins (Beadle and Tatum)
What is the central dogma of biology?
500
The idea of Matthew Meselson and Franklin Stahl
What is semi-conservative replication?
500
The steps of transcription
1. The DNA molecule is unzipped 2. RNA polymerase attaches to the DNA molecule and bonds the appropriate base to each exposed base on the DNA molecule. 3. Instead of thymine, RNA polymerase bonds uracil to adenine. 4. Transcription ends when the RNA polymerase reaches a sequence of bases called the termination signal.

The decoding of mRNA into a protein
What is translation?
500
The differences between DNA and RNA
What are? 1. The sugar in RNA is ribose instead of deoxyribose. 2. RNA is generally single-stranded. 3. RNA contains uracil in place of thymine.
