Mendel and gene idea
What is a gene
A section of DNA that codes for a trait
What are the nitrogenous bases
Adenine, guanine, thymine, cytosine
What is translation and where does it occur
The synthesis from mRNA to proteins and occurs in the ribosomes
What is a proto-oncogenes
The corresponding normal cellular genes that are responsible for normal cell growth and division
Free 100
Yay
What is a punnets square
Used to determine probability of different combinations
What is topoisomerase
Relieves the strain of twisting of the double helix
what is redundant
More than one codon may specify a particular amino acid
What is “junk DNA”?
Genes that do not encode for a protein product or known functional RNA
what does PCR stand for
polymerase chain reaction
What is incomplete dominance
somewhere between the phenotypes of the two parental varieties (blend)
What does DNA ligase do
Joins pieces of DNA (Okazaki fragments)
Triplet code
A series of non overlapping, three-nucleotide words
what are exons/introns?
Exons are expressed and introns are ”in the way”
What is PCR used for?
To diagnose certain infection diseases and genetic changes
Law of segregation
When the two alleles for a heritable character separate during gamete formation and end up in different gametes
If cytosine makes up 42% of the nucleotides in a sample of DNA, what percentage of the nucleotides would be thymine
42%
A particular triplet of bases in the template strand of DNA is 5’-AGT-3’. What would be the corresponding codon for the mRNA that is transcribed
3’-UCA-5’
What is histone acetylation
“Spool” that DNA is wrapped around
How many people are in this class
15
What is polygenic inheritance
A single phenotypic character is affected by two or more genes
Who reported that DNA composition varies from one species to the next
Erin Chargaff
What is central dogma
Cells are governed by a cellular chain of command: DNA to RNA to protein
what are ras and p53?
Ras is proto-oncogene and p53 is a tumor suppressor and both common in human cancers
