Regulation of gene expression
What is the flow of information from DNA to BLANK to BLANK
RNA to protein
What is the difference in DNA between 2 cells in the same organism
What is does PCR stand for
polymerase chain reaction
If the coding strand of DNA is AGACT what Would the mRNA strand be.
AGACU
What are the three components of DNA
A phosphate group, deoxyribose sugar, and a nitrogenous base
What would happen if DNA didn’t have promoter sequences
transcription wouldn’t happen
Do all cells have activator proteins for all function in an organism
no
What cellular object does the splinting of a specific DNA sequence
an enzyme
what Would happen if DNA didn’t have a hydroxyl group
Parts of DNA molecules wouldn’t be able to bind from dehydration synthesise
what is considered to be the “glue“ in DNA replication
Ligase
What is the region of DNA after the regaultorry sequence that is untranslated
exon
What are promoters sequences
DNA regions that signal starting points for transcription
What 2 things allow gel electrophoresis to work (properties of the molecule itself)
how negatively charged the molecule is and the size of the fragments
What molecule transports amino acids to the ribosomes
tRNA
What does SSBs stand for
Single stranded binding protein
The interaction of regulatory proteins with regulatory sequences controls BLANK
transcription
What do negative regulatory molecules do
inhibit gene expression by blocking transcription by blocking RNA polymerase.
What are the steps for PCR to work
DNA is denatured then primers are added then DNA is replicate.
What is the hydydroxly group replaced with when a part of DNA is added to another part of DNA
A phosphate
If a DNA molecule had guanine on the template strand would an mRNA have a purine or pyrimidnes
Pyrimidnes
Epigentic changes involve a reversible change in BLANK and BLANK
Histones and DNA
What 3 things need to interact to active transcription
regulatory genes, regulatory proteins and transcription factors
What is it called when 2 primers are combined
primer dimer
If a Gene on RNA had 30% adenine how much of the other nucleotides would the coding strand have.
30% adenine, 30% thymine, 20% guanine, 20% cytosine.
If a cell had a genetic mutation to where DNA would always super coil. What would the nucleus be missing
Topoisomerase
