What is DNA and its structure?

Back

Deoxyribonucleic Acid (DNA) is a double helix composed of nucleotides, which include a five-carbon sugar (deoxyribose), a nitrogen base, and a phosphate.

Front

What are the nitrogen bases in DNA?

Back

Cytosine, Guanine, Thymine, and Adenine.

Front

What is Gene Expression?

Back

Gene Expression is the production of RNA/proteins from the DNA information.

Front

What is Transcription?

Back

Transcription is the process by which DNA is 'read' to form mRNA.

Front

What is Translation?

Back

Translation is the process by which mRNA is converted into amino acids (polypeptides) in ribosomes.

Front

What are the stages of Mitosis?

Back

Prophase, Metaphase, Anaphase, Telophase.

Front

What is Apoptosis?

Back

Apoptosis is programmed cell death, a process that adjusts and controls cell numbers within tissues.

Front

What is Histology?

Back

Histology is the study of tissue structure.

Front

What are the four main types of tissue?

Back

Epithelial, Connective, Muscle, and Nervous tissue.

Front

What is the function of Epithelial Tissue?

Back

Epithelial Tissue covers and protects surfaces, both outside and inside the body.
