Bio 1 - Origin of life and epigenetics Flashcards
1
Q
Miller and Urey experiment
A
Were able to produce amino acids as experiments. Oparin and Haidane challenged that results were due to chance?
2
Q
Primordial soup
A
Idea that seas were full of organic molecules
3
Q
Heterotrophs
A
First organisms from primordial soup. Could feed on the complex organic compounds.
4
Q
RNA world hypothesis
A
That RNA molecules were the first organic substances to arise. RNA molecules are easier to form than DNA. They can also act as catalysts (in ribosomes).
5
Q
Epigenetic marks
A
Methyl, acetyl, phosphate, ubiquitination. More often attached to histones. Methyl group is attached to DNA
6
Q
Extra nuclear inheritance
A
Genes not in the nucleus (mitochondria - maternal inheritance pattern)
