Topic 7.7 - Common Ancestry 𖦹⋆｡°✩

Question 1

what is evidence supporting common ancestry for all eukaryotes

Answer 1

༻ membrane-bound organelles
༻ linear chromosomes
༻ genes that contain introns

Question 2

what are the structural similarities between chloroplasts and mitochondria

Answer 2

༻ have double-membrane
༻ contain circular genomes
༻ contain ribosomes
༻ endosymbiotic theory
༻ contain nucleus with linear chromosomes

Question 3

what is the endosymbiotic theory

Answer 3

the theory that describes the process and evidence supporting these similarities

Question 4

what other eukaryotic organelles have similar structure and function

Answer 4

ER, Golgi, lysosomes, vacuoles

Question 5

what are chromosomes made of

Answer 5

tightly coiled DNA with histone proteins

Question 6

eukaryotes are made of multiple linear chromosomes. how are they similar in eukaryotes

Answer 6

༻chromosomes made of tightly coiled DNA with histone proteins
༻ capped with telomeres
༻ found inside the nucleus
༻ genomes are large

Question 7

how do eukaryotic genomes differ from prokaryotic genomes

Answer 7

༻ contain single circular chromosomes
༻ occurs in teh cytoplasm
༻ genomes are small

Question 8

what are introns

Answer 8

༻ do not code for proteins
༻ DNA processing removes introns prior to protein synthesis
