18
Q

What happens when a proteins shape is altered?

A

It can no longer function

19
Q

What happens to a polypeptide chain during denaturation?

A

20
Q

What is an amino acid sequence of a polypeptide programmed by?

A

the unit of inheritance known as the gene

21
Q

What makes up genes?

A

DNA

22
Q

What is RNA, and what does it do?

A

DNA uses RNAs to transcribe information and the RNA translates it into proteins.

23
Q

What is DNA and RNA composed of?

A

Monomers called Nucleotides

24
Q

What are nucleotides made of?

A

A five carbon sugar called ribose in RNA and deoxyribose in DNA, a phosphate group, and a nitrogenous base.

25
Q

What are the nitrogenous bases of DNA

A

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

26
Q

What nitrogenous bases does RNA have

A

The same as DNA but thymine has been replaced with Uracil (U)

27
