Nucleic Acids

Question 1

What 3 components make up individual nucleotides?

Answer 1

Pentose sugar
Phosphate group
N containing organic base : Cytosine, Thymine, Uracil, Adenine and Guanine

Question 2

How are the 3 components of nucleotides joined together?

Answer 2

By a condensation reaction, forming a single nucleotide (mono nucleotide)

Question 3

What happens between two mononucleotides?

Answer 3

Joined together by a condensation reaction between deoxyribose sugar of one mononucleotide and the phosphate group of another
A phosphodiester bond is formed and the new structure is called a dinucleotide

Question 4

What does a continued link of mononucleotides form?

Answer 4

Polynucleotide

Question 5

What is RNA?

Answer 5

Ribonucleic acid is a polymer made up of nucleotides. It is a single, relatively short polynucleotide chain which the pentose sugar is always ribose and the organic bases are A, G, C and U

Question 6

What is DNA made up of?

Answer 6

Nucleotides (have three basic components)

Question 7

What are three types of RNA?

Answer 7

One type transfers genetic info from DNA to ribosomes
The ribosomes themselves are made up of proteins and another type of RNA
A third type is involved in protein synthesis
