Front

How many layers of phospholipids make up the cell membrane?

Back

The cell membrane is made up of two layers of phospholipids, known as a phospholipid bilayer.

Front

What is the process of making proteins called?

Back

The process of making proteins is called Translation.

Front

What do codons in mRNA code for?

Back

Codons in mRNA code for specific amino acids. For example, the mRNA strand AUG GCA UCC AGC UUU UAG codes for Methionine, Alanine, Serine, Serine, Phenylalanine, and a Stop signal.

Front

What are the three main steps in the cell cycle?

Back

The three main steps in the cell cycle are Interphase, Mitosis, and Cytokinesis.

Front

What is the cell cycle?

Back

The cell cycle is a series of events that cells go through as they grow and divide.

Front

What is a phospholipid?

Back

A phospholipid is a type of lipid molecule that is a major component of cell membranes, consisting of two fatty acids, a glycerol unit, and a phosphate group.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the cellular structures responsible for synthesizing proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically messenger RNA (mRNA), which carries the genetic information to the ribosome.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is cytokinesis?

Back

Cytokinesis is the final step of cell division, where the cytoplasm of a parental cell is divided into two daughter cells.
