Proteins and Nucleic Acids

Front

What is the primary difference between DNA and RNA?

Back

DNA uses deoxyribose for its sugar, while RNA uses ribose.

Front

What elements are commonly found in proteins?

Back

Proteins are made up of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and sometimes sulfur (S).

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.

Front

What type of bond connects amino acids in a protein?

Back

Amino acids are connected by peptide bonds.

Front

What is the structure of RNA?

Back

RNA is typically single-stranded and can have secondary structures, unlike DNA which is double-stranded.

Front

What are the three components of a nucleotide?

Back

A nucleotide consists of a phosphate group, a sugar (ribose in RNA, deoxyribose in DNA), and a nitrogenous base.

Front

What type of amino acids would you expect to find in the hydrophobic region of a membrane protein?

Back

You would expect to find non-polar amino acids in the hydrophobic region.

Front

What is the role of ribose in RNA?

Back

Ribose is the sugar component of RNA nucleotides.

Front

What is a polymer?

Back

A polymer is a large molecule made up of repeating subunits, such as proteins made from amino acids.

Front

What is the function of proteins in biological systems?

Back

Proteins serve various functions including catalyzing reactions (enzymes), providing structure, and facilitating communication.
