Reproductive cells that transmit genes from generation to the next. A 100
What are gametes? A 100
The body cells of an organism. A 200
What are somatic cells? A 200
Chromosomes that carry the genes for the same traits A 300
What are homologues (homologous chromosomes)? A 300
Chromosomes that do not determine gender. A 400
What are autosomes? A 400
In plants and algae, produced by haploid cells dividing mitotically. A 500
What is a gametophyte? A 500
Alternative versions of genes B 100
What are alleles? B 100
An organism ’ s expressed physical trait B 200
What is phenotype? B 200
According to a 19 th Century monk, the two alleles for a trait separate during gamete formation and each allele has an equal chance of going to an offspring B 300
What is Mendel ’ s Law of Segregation? B 300
The crossing of a recessive homozygote with a second organism expressing the dominant phenotype to determine the second organisms genotype. B 400
What is a test cross? B 400
Explains why the alleles for pea color separate completely independently from the alleles for pea plant height during gamete formation. B 500
What is Mendel ’ s “ Law of Independent Assortment ” ? B 500
Two of these form between adenine and thymine and three between cytosine and guanine. C 100
What are hydrogen bonds? C 100
These enzymes catalyze the lengthening of a DNA strand one nucleotide at a time. C 200
What are DNA polymerases? C 200
During transcription, only this DNA strand is transcribed. C 300
What is the template strand? C 300
DAILY DOUBLE C 400 DAILY DOUBLE Place A Wager
These separate pieces are the result of synthesis along the lagging DNA strand and are sealed together by DNA ligase. C 400
What are Okazaki fragments? C 400
The short RNA piece that is used to start DNA replication.. C 500
What is a primer? C 500
The end result of meiosis. D 100
What are four daughter cells? D 100
Homologues pair up during Prophase I, forming this structure. D 200
What is a tetrad? D 200
This exchange of homologous parts of two non-sister chromatids further increases variation in reproduction. D 300
What is “ crossing over ” ? D 300
Chromosomes are moved toward opposite ends of the cell but the chromatids stay connected. D 400
What is Anaphase I? D 400
Results from failure of homologous chromosomes to separate in Meiosis I or sister- chromatids to separate in Meiosis II. D 500
What is nondisjunction? D 500
The “ writing ” of RNA from the DNA in the nucleus E 100
What is transcription? E 100
Large pieces of newly made mRNA are removed. E 200
What is RNA splicing? E 200
The pieces of RNA that are spliced out of a eukaryotes mRNA. E 300
What are introns? E 300
Larger than their counterparts in prokaryotes, their RNA is made in the nucleus. E 400
What are ribosomes? E 400
Along with a poly-A-tail, this is added to the transcribed RNA.. E 500
What is a 5 ’ cap? E 500
Viruses that infect bacteria. F 100
What are phages (bacteriophages)? F 100
In this virus life cycle, the virus DNA is incorporated into the host DNA and does NOT break open the host cell. F 200
What is a lysogenic cycle? F 200
Misfolded infectious proteins that cause normal proteins to misfold. F 300
What are prions? F 300
The alteration of a bacteria ’ s genotype by the uptake of naked, foreign DNA. F 400
What is transformation? F 400
Made of an operator, promoter and the genes they control. F 500
What is an operon? F 500
