Question

Please label each of the nucleic acid characteristics below as belonging to DNA, RNA or both.

1. Forms a double-helix shaped secondary structure

2. can fold into complex shapes and sometimes have catalytic activity

3. sometimes attaches attaches thymine to its sugar's number 1 carbon atom

4. nucleotide monomers connected via phosphodiester bonds between one nucleotides 5' carbon and the adjacent nucleotides 3' carbon

5. possesses a 2' -OH group

6. stores genetic information

7. candidate as the potential first self-replicating molecule on the early earth

8. forms purine-pyrimidine base pairs

Answer 1

Kindly refer the table given below for the answer

DNA	RNA	Both DNA and RNA
Sometimes attaches attaches thymine to its sugar's number 1 carbon atom	1. Can fold into complex shapes and sometimes have catalytic activity 2. Possesses a 2' -OH group 3. Candidate as the potential first self-replicating molecule on the early earth	1. Forms a double-helix shaped secondary structure Eg. A-DNA, B-DNA and tRNA 2. Nucleotide monomers connected via phosphodiester bonds between one nucleotides 5' carbon and the adjacent nucleotides 3' carbon 3. Stores genetic information 4. Forms purine-pyrimidine base pairs For DNA it is always true. However, we can see purine-pyrimidine base pairing in RNA when RNA form double helical structures. Eg. tRNA
