Ribonucleotides

This animation displays the four different types of RNA building blocks: GTP, ATP, UTP, and CTP. In addition to one of four possible bases, either guanine, adenine, cytosine, or uracil, each ribonucleotide is characterized by a ribose sugar and 5’ phosphate groups, shown in red and green. When a base is bonded to a ribose sugar and phosphate groups, its name is changed such that, for example, uracil is referred to as uridine triphosphate.

Question 1: When uracil is bonded to a ribose sugar and triphosphate groups, its name is changed and it is referred to as ____________.
  1. GTP
  2. ATP
  3. UTP
  4. CTP


Answer 1

Answer - (c) UTP

Question 2: What are the building blocks of RNA?
  1. ATP, BTP, GTP, and UTP.
  2. ATP, UTP, CTP, and RNA.
  3. UTP, TTP, ATP, and CTP.
  4. ATP, CTP, GTP, and UTP.


Answer 2

Answer - (d) ATP, CTP, GTP, and UTP

Question 3: What are the building blocks of DNA?
