DNA & Protein Synthesis Short Answer Quiz

Define deoxyribonucleic acid. It is the hereditary material in cells that contains the instructions for a cell to make all the other molecules it needs to function

Describe the location of DNA. DNA makes up chromosomes which are in the nucleus of cells

What type of molecule is DNA?

• Nucleic acid polymer

• Protein

• Carbohydrate

• Lipid

Name and describe the monomers of DNA. Nucleotides are the monomers of DNA. DNA nucleotides have 3 parts: deoxyribose sugar, a phosphate group, and a nitrogenous base

What are the 2 different forms of nitrogen bases?

• 2 rings

• 1 ring

• 3 rings

• 4 rings

List the four nitrogen bases in DNA.

• Thymine, Cytosine, Adenine, Guanine

• Uracil, Cytosine, Adenine, Guanine

• Thymine, Cytosine, Adenine, Thymine

• Thymine, Cytosine, Adenine, Thymine

State the name and describe the shape of a DNA molecule. Double helix; a twisted ladder shape

Define DNA replication and discuss when it occurs and why it is important. The process of copying the DNA molecule. Replication occurs before cell division and it is important because it ensures that each new cell receives the appropriate amount of DNA

List and briefly describe the two stages of protein synthesis. Transcription: RNA 'writes down' the DNA code. Translation: Code is changed from nucleic acid language to amino acid language

What is RNA and how is it different from DNA? RNA stands for ribonucleic acid. RNA is different from DNA because it is single-stranded, the sugar is ribose, and it has the nitrogen base uracil instead of thymine
