Gene Expression

Human Genetics Exam 1

TermDefinition
exocrine cells release digestive enzymes
endocrine cells secrete hormones into the blood
proteomics study of the protein products formed from gene expression in a particular cell, tissue, organ, or body under certain conditions
promoter DNA sequence where transcription by RNA polymerase begins
enhancer DNA sequence that when bound by TF, enhance transcription
activator transcription factor ---> binds enhancer region ---> increases gene expression
repressor TF ---> binds silencer region ---> decrease gene expression
silencer DNA sequence that when bound by TF, shuts off transcription
when chromosomes are condensed: no transcription occurs
acetylation increases transcription, acetylase adds acetyl groups to lysine, gives it a negative charge
methylation decreases transcription, methyl groups bind cytosine, proteins shut off DNA access
phosphorylation increases transcription by promoting acetylation, adds phosphate groups to serine, gives it a negative charge
Alpha Thalassemia undermethylation, can't make the right hemoglobin chain, anemic
ICF Syndrome undermethylation of DNA repeats, unstavle centromeres, immune deficient
Rett Syndrome fail to remove acetyls from histones, neurodegeneration, seizures, motor loss
Rubinstein-Taybi Syndrome inappropriately adds acetyl groups, intellectual disability, broad toes/thumbs
gene expression after you die: increase in inflammation, immune, stress genes, embryonic development genes, cancer causing gene

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
