Chapter 17 Review

two steps of gene expression

• replication and recombination
• transcription and translation
• mitosis and meiosis
• mutation and adaptation

what is transcription in gene expression

• Copying DNA to form mRNA

• Synthesizing a protein from mRNA

• copying a gene's DNA sequence to make an RNA molecule

• Breaking down proteins into amino acids

what is translation in gene expression

• Copying DNA to form mRNA
• Synthesizing a protein from mRNA
• Breaking down proteins into amino acids
• Converting RNA into DNA

where does transcription happen in gene expression

• mitochondria
• cytoplasm
• cell membrane
• nucleus

where does translation happen in gene expression

• mitochondria
• cytoplasm
• nucleus
• endoplasmic reticulum

what is DNA

• Genetic material
• A species of bird
• A type of pasta
• A type of computer programming language

what is RNA

• RNA is a nucleic acid that is essential for protein synthesis.
• RNA is a type of carbohydrate found in plants
• RNA is a type of gas used in welding
• RNA is a type of rock formation found in caves

different types of RNA

• DNA, RNA, mRNA
• ATP, ADP, AMP
• Protein, Carbohydrate, Lipid
• mRNA, tRNA, rRNA

what is promoter sequence

• Region of DNA where RNA polymerase binds to initiate transcription
• A type of protein found in the cell membrane
• A segment of RNA that codes for a specific protein
• A region of DNA that prevents transcription from occurring

what is terminator sequence

• A type of mutation in DNA
• A sequence in DNA that signals termination of transcription to RNA Polymerase

• A type of protein in DNA
• A specific type of DNA replication
