Nucleic acids

Question 1

Pyrimidines (2x h bonds)

Answer 1

longer name= shorter nuke acid = T,U,C

Question 2

Purines (3x h bonds)

Answer 2

shorter name= longer nuke acid = A,G

Question 3

Ribose

Answer 3

5 membered ring, gives further possible bonding structures

Question 4

Deoxyribose

Answer 4

5 membered ring, deoxygenated at the 2 position

Question 5

Replication

Answer 5

helicase splits in to 2 strands
monomers for DNA added for DNA Polymerase

Question 6

Transcription

Answer 6

Transcription factors signal to RNA polymerase where to be
produces mRNA –> codes specific proteins

Question 7

Translation

Answer 7

in the ribosomes between the subunits
mRNA in, DNA out
tRNA brings codons in to build correct chain of AA

Question 8

Subunit roles

Answer 8

large unit links AA
small unit reads RNA
