Rna world and Luca

Question 1

What is Rna

Answer 1

Phosphate group
basic structure
many roles

Question 2

Making/getting RNA

Answer 2

Do novo
Panspermia

Question 3

Do-novo

Answer 3

Water, methane,ammonia, hydrogen,,carbon monoxide (On Earth already)
specific order and method

Question 4

Panspermia

Answer 4

Life on Earth began from elsewhere
Material based Panspermia seed (M-BPS)

Question 5

Assembly of chains

Answer 5

Montmorillonite clay
Crystal structure (catalyzes polyerization,assembly)
Rna polynucleotides form
start of amino acid chain

Question 6

RNa to protein (main Rna)

Answer 6

Messenger Rna-codes
Ribosmal RNa-transports
Transfer rna-assembles
MRT.

Question 7

order of protein assembly important

Answer 7

Need instructions
“like ikea
Can’t put together wrong way

Question 8

Assembly of proteins

Answer 8

Cyclic process- dumb testosterone said RIP
selection of proteins
Functional variants
Diversification, translation,screening, or selection, Replication
Stress=specific phenotype

Question 9

Timeline of life

Answer 9

Prebiotic chemistry-pre-cellular life-early cellular life-Luca-Evolutionary diversification
RNA world assembly,and replication
generation-RNA ribosome and selection

Question 10

LUCA

Answer 10

Last universal common ancestor
forerunner of all living things
complex
had organelles
Cell?

Question 11

Formation of eukaryotes

Answer 11

prokaryotes lack membrane-bound organelles
where do they come from?
Ways:Autogenic,endosymbiotic

Question 12

autogenic (Autogenous)

Answer 12

ER, Golgi, Lysosomes, nuclear membrane
Eukaryotes arose directly from a single prokaryote ancestor
infoldings of the prokaryote plasma membrane

Question 13

Endosymbiotic

Answer 13

Mitochondria,chloroplasts
some organelles of modern eukaryotic cells invaded from
symbiotic associations with prokaryotic ancestors
2 endosymbiosis events
overtime development and diversification
