Cell Bio- 10 Genes & genomes

Question 1

True or False: The genomes of eukaryotes are typically smaller and less complex than those of prokaryotes

Answer 1

false

Question 2

True or False: Genome size in eukaryotes is directly proportional to the organism’s complexity.

Answer 2

false/

Question 3

True or False: Salamanders and lilies have genomes that contain more than ten times the amount of DNA than the human genome.

Answer 3

true

Question 4

True or False: The larger genome size in eukaryotes as compared to prokaryotes is mainly due to a greater number of protein-coding genes.

Answer 4

false

Question 5

True or False: Non-coding DNA is responsible for the discrepancies in genome size among different eukaryotic organisms.

Answer 5

true

Question 6

introns

Answer 6

segments of non coding sequence

Question 7

exons

Answer 7

coding segments of the gene

Question 8

how does introns are removed?

Answer 8

splicing

Question 9

T/F: The entire gene is transcribed to yield a long RNA molecule & the introns are then
removed by splicing, such that only exons are included in the mRNA.

Answer 9

true
