Mish Mash
100
This man used peas to describe the basic principles of heredity.
Who is Gregor Medel?
100
Single rings, include C, T and U
What is pyrimidine?
100
Sugar present in RNA
What is ribose?
100
Enzyme use to unzip the DNA double helix
What is helicase?
100
Worked with Rosalind Franklin on determining DNA structure
What is Maurice Wilkins?
200
This is the location of a gene on a chromosome
What is loci?
200
Discovered that the number of purines = number of pyrimidines
Who is Chargraff?
200
This is the central dogma of molecular biology
What is DNA --> RNA --> Protein?
200
Location that new nucleotides are added to a new DNA strand
What is 3' end?
200
This brings the correct amino acid during translation
What is tRNA
300
Variation of a gene that determines the same trait
What is allele?
300
Term given to the opposite orientation of complementary DNA strands
What is antiparallel?
300
Nucleotide sequence where RNA polymerase binds
What is promoter?
300
Adds new nucleotides during DNA replication and proofreads new DNA strand
What is DNA polymerase?
300
Along with RNA polymerase, these must be present for transcription to begin
What are transcription factors?
400
Involves a cross between an individual of unknown genotype and a homozygous recessive individual
What is test cross?
400
Type of bond found between the nitrogenous bases of complementary DNA strands
What is hydrogen?
400
Change in a single base pair that changes an amino acid into a stop codon
What is nonsense?
400
Adds short RNA primer before DNA replication begins
What is primase?
400
This provides the energy necessary to form covalent bonds between amino acids during translation
What is GTP
500
These are 2 genes that lie close together, they do not assort independently
What are linked genes?
500
Method of DNA replication in which each half of a double helix serves as a template for a new DNA strand
What is semiconservative replication?
500
Must be removed from mRNA before it can be translated
What are introns?
500
Small fragments of DNA formed on the lagging strand, sealed with primase
What are Okazaki fragments?
500
this would be the phenotypic ratio of a dihybrid cross between 2 heterozygotes
What is 9:3:3:1
