DNA and Protein Synthesis

In a eukaryotic cell, DNA is only found in the _____________ .

• cytoplasm

• ribosome

• nucleus

• mitochondria

Protein synthesis occurs in two stages:

• (1) replication (2) mutation

• (1) replication (2) division

• (1) transcription (2) translation

Where does DNA replication occur?

• cytosol

• ribosome

• chloroplast

• nucleus

When a mistake is made during DNA copying in replication or protein synthesis, it is known as:

• part of the cell cycle

• first step of transcription

• first step of translation

• a genetic mutation

Which statement best explains how genes and proteins are related?

• Genes are the building blocks of proteins.

• Proteins are segments of DNA that code for genes.

• Proteins are the building blocks of genes.

• Genes are segments of DNA that code for proteins.

Genetic information generally flows in one direction. Which of the following best represents this flow?

• RNA --> Protein --> DNA

• DNA --> RNA --> Protein

• Protein --> RNA --> DNA

• DNA --> Protein --> RNA

DNA and RNA are both made of:

• nucleotides

• doxyribose

• uracil

• thymine

In RNA, uracil takes the place of the DNA nitrogen base called

• guanine
• cytosine
• thymine
• adenine

In what process is mRNA synthesized?

• Transcription

• Translation

• DNA Replication

• Mitosis

Where does Translation take place?

• chloroplast

• ribosome

• nucleus

• chromosome
