AP Biology Unit 8: Gene Expression & Regulation Notes Pt. 1

Activators

________ are used to increase transcription while repressors are used to decrease the transcription.

RNA polymerase

________ starts transcribing a gene at the correct place on the DNA of eukaryotes differently.

GGG

________ translates into glycine.

Conservative

________: Wraps around histone protein and makes exact duplicate.

Mitosis

________ creates two genetically identical daughter cells that are identical to the parent cell and are diploid.

Testcross

________ shows that the recombination frequency between A and B is 28 % and between A and C is 12 %.

Dispersive

________: Cut into 10- 12 nucleotides and each segment is copied.

MiRNA

________ has a hairpin like structure and is able to break down mRNA and prevent translation.

DNA

________ is antiparallel, meaning that there is a strand that runs from the 5 to 3 while the opposite strand runs from 3 to 5.

Bases

________ can only be added to the 3 end, so one strand is a leading strand while the other is a lagging strand.

Meiosis

________ creates four haploid cells that have genetic variation because there are steps like crossing over and the independent assortment that happens in ________ 1.

Amino acid

________: Cys Ala Gly Met.
