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 ____________.
- GTP
- ATP
- UTP
- CTP
Answer 1
Answer - (c) UTP
Question 2: What are the building blocks of RNA?
- ATP, BTP, GTP, and UTP.
- ATP, UTP, CTP, and RNA.
- UTP, TTP, ATP, and CTP.
- ATP, CTP, GTP, and UTP.
Answer 2
Answer - (d) ATP, CTP, GTP, and UTP
Question 3: What are the building blocks of DNA?
- ATP, BTP, CTP, and DTP.
- ATP, CTP, GTP, and UTP.
- UTP, TTP, ATP, and CTP.
- ATP, CTP, GTP, and TTP.
Answer 3
Answer - (d) ATP, CTP, GTP, and TTP.
