Nucleic Acids And The Central Dogma Of The Cell

Question 1

Are polymers in which the monomer units are nucleotides.

Answer 1

Nucleic Acids

Question 2

Bases that are Purines (Double-ring)

Answer 2

Adenine and Guanine

Question 3

Bases that are pyrimidines (single-ring)

Answer 3

Cytosine, Uracil, and Thymine

Question 4

Difference of Purines: Adenine and Guanine

Answer 4

Adenine (NH2 is on top of the second ring and without O)

Guanine (contains double bond and O at the top of the second ring)

Question 5

Carries instructions for protein synthesis (genetic information) from DNA

Answer 5

mRNA

Question 6

Facilitates the conversion of hnRNA to mRNA.
– Contains from 100 to 200 nucleotides

Answer 6

Small Nuclear RNA

Question 7

Combines with specific proteins to form ribosomes
- the physical site for protein synthesis
- Ribosomes have molecular masses on the order of 3 million

Answer 7

Ribosomal RNA

Question 8

Delivers amino acids to the sites for protein synthesis and are the smallest (75–90 nucleotide units)

Answer 8

tRNA

Question 9

A process that ultimately leads to the formation of several different protein variants from a single gene

Answer 9

Alternative Splicing
