NUCLEIC ACID

Question 1

The function of the Nucleic Acid

Answer 1

Nucleic acid allows organisms (from viruses to humans) to carry messages regarding the characteristics they should exhibit, from one generation to the next.

Question 2

What are thr two types of Nucleic Acid

Answer 2

• Deoxyribonucleic acid (DNA) and
• Ribonucleic acid (RNA).

Question 3

What are nucleicacids made up of?

Answer 3

Both substances are made up of nucleotides (which consist of a 5-carbon sugar group, a phosphate group, and a nitrogenous base- they differ slightly,

however in various ways)

Question 4

Describe RNA

LOCATION, SUGAR, NITROGENOUS BASE, STRUCTURE AND FUNCTION

Answer 4

Location: In the nucleus and cytoplasm

Sugar : Ribose

Nitrogenous Base Adenine- uracil A-U

Cytosine- guanine C-G

Structure: Single strand

Function: Transfer the genetic code necessary for the creation of proteins from the nucleus to the ribosome (so the DNA never has to leave the nucleus)

Question 5

Describe DNA

LOCATION, SUGAR, NITROGENOUS BASE, STRUCTURE AND FUNCTION

Answer 5

Location: In the nucleus

Sugar: Deoxyribose

Nitrogenous bade: Adenine- thymine A - T

Cytosine- guanine C-G

Structure: Double helix (two conjoined, twisted strands)

Function: Long term storage and transmission of genetic information

Question 6

What are the four different bases

Answer 6

There are four different bases in DNA:

• thymine, T
• adenine, A
• guanine, G
• cytosine, C

Question 7

What are the base pairs?

Answer 7

• thymine pairs with adenine (T-A)
• guanine pairs with cytosine (G-C)
