Front

What are nucleotides made up of?

Back

Nucleotides are made up of a sugar, a phosphate group, and a nitrogenous base.

Front

What are proteins?

Back

Proteins are organic macromolecules composed of chains of amino acids that form the structural components of organisms.

Front

What can result from a disruption in the cell cycle?

Back

A disruption in the cell cycle can lead to cancer.

Front

What shape did Rosalind Franklin determine the DNA molecule to be?

Back

Rosalind Franklin determined that the shape of the DNA molecule is a twisted ladder.

Front

During which phases of the cell cycle does the cell grow?

Back

The cell grows during the G1 and G2 phases of the cell cycle.

Front

What is the function of nitrogenous bases in nucleotides?

Back

Nitrogenous bases are essential for encoding genetic information in DNA and RNA.

Front

What are the four main types of organic macromolecules?

Back

The four main types of organic macromolecules are carbohydrates, proteins, lipids, and nucleic acids.

Front

What is the role of the cell cycle?

Back

The cell cycle is the process by which a cell grows, duplicates its DNA, and divides to form new cells.

Front

What is x-ray crystallography used for in biology?

Back

X-ray crystallography is used to determine the three-dimensional structure of biological molecules, such as DNA.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, linked together by peptide bonds.
