DNA Replication

Question 1

what does tRna do

Answer 1

transports amino acids to ribosome during translation

Question 2

what sugar is used in RNA

Answer 2

ribose sugar

Question 3

what sugar is used in DNA

Answer 3

deoxyribose

Question 4

what bases are in DNA

Answer 4

A,G,T,C

Question 5

what bases are used in RNA

Answer 5

A,G,U,C

Question 6

what is the central dogma of biology?

Answer 6

the process of genetic info - DNA -> RNA -> Protein

Question 7

What is rRna

Answer 7

forms peptide bonds between amino acids forming proteins when its being transcribed

Question 8

what is an exon

Answer 8

coding regions of a expressed gene

Question 9

whats an intron

Answer 9

a non-coding region that is spliced out during RNA translation

Question 10

what is splicing

Answer 10

removing the introns from the exons to make mature RNA

Question 11

do prokaryotes undergo splicing

Answer 11

no

Question 12

whats the purpose of the 5’ cap in splicing

Answer 12

to stop mRNA from being degraded

Question 13

where does splicing occur

Answer 13

nucleus of eukaryotes

Question 14

whats a spliceosome

Answer 14

a large complex protein that removes introns and ligates the exons together

Question 15

why doesn’t splicing occur in prokaryotes

Answer 15

they lack introns

Question 16

whats alternative splicing

Answer 16

when a single gene creates multiple proteins by splicing exons together in different combinations

Question 17

what happens if a splicing error occurs

Answer 17

loss of functional proteins such as cancer or genetic disorders

Question 18

why does alternative splicing occur

Answer 18

increases protein diversity as it allows a single gene to produce different proteins
