What is a saturated fatty acid?

Back

A saturated fatty acid is a type of fatty acid that has no double bonds between carbon atoms, resulting in a straight chain structure.

Front

What is an unsaturated fatty acid?

Back

An unsaturated fatty acid is a type of fatty acid that contains one or more double bonds between carbon atoms, causing kinks in the chain.

Front

What is the main difference between saturated and unsaturated fatty acids?

Back

The main difference is that saturated fatty acids have no double bonds, while unsaturated fatty acids have one or more double bonds.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of nucleic acids, consisting of a sugar (deoxyribose in DNA), a phosphate group, and a nitrogenous base.

Front

What are the components of a nucleotide?

Back

A nucleotide is made up of three components: a sugar, a phosphate group, and a nitrogenous base.

Front

What role do hydrogen bonds play in DNA structure?

Back

Hydrogen bonds hold the two strands of the DNA double helix together, stabilizing its structure.

Front

What forms the backbone of a DNA strand?

Back

The backbone of a DNA strand is formed by alternating sugar and phosphate groups.

Front

What is the function of the phosphate group in a nucleotide?

Back

The phosphate group links nucleotides together, forming the backbone of the DNA or RNA strand.

Front

What is the significance of the nitrogenous base in a nucleotide?

Back

The nitrogenous base is responsible for encoding genetic information and pairing with complementary bases in the DNA structure.

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).
