Multiple Choice

What are the smaller units that make up DNA?

• Nucleotides
• Amino acids
• Proteins
• Lipids

Multiple Choice

What do we call a segment of DNA that codes for one protein?

• protein strand
• gene
• nucleotide
• chromosome

Multiple Choice

What molecule carries a copy of a gene from the nucleus to the ribosome?

• ribosomal RNA (rRNA)
• transfer RNA (tRNA)
• messenger RNA (mRNA)
• deoxyribonucleic acid (DNA)

Multiple Choice

What structure reads mRNA and builds a protein?

• Nucleus
• Endoplasmic reticulum
• Golgi apparatus
• Ribosome

Multiple Choice

We are made of trillions of cells, including muscle cells, nerve cells, skin cells, and more. How do we have all of these different kinds of cells?

• Different cells in a multicellular organism all have the same DNA, but cells can express different proteins

• Different cells in a multicellular organism all have different DNA

• DNA becomes mutated depending on the cell type that it is found in

• Cells can fuse to become different kinds of cells. Cells that fuse more become more complex

Multiple Choice

What do we call a change in the DNA sequence?

• mutation
• chromosomal rearrangement
• phenotypic variation
• genetic drift

Multiple Choice

Which type of cell division produces gametes (sperm/egg)?

• Meiosis
• Budding
• Binary fission
• Mitosis

Multiple Choice

What occurs during meiosis that leads to diversity of the 4 daughter cells?

• Crossing over and independent assortment lead to genetic diversity in the daughter cells.
• Only random mutations contribute to genetic differences.
• Meiosis produces identical daughter cells without variation.

• Chromosomal duplication occurs without any genetic exchange.

Multiple Choice

What do we call the different versions of a gene that a person can inherit?

• Genotypes
• Alleles
• Genes
• Chromosomes

Multiple Choice

What type of inheritance occurs when neither allele is dominant, resulting in a blended phenotype?

• Polygenic inheritance
• Codominance
• Incomplete dominance
• Epistasis

Multiple Choice

What tool do scientists use to separate pieces of DNA by size?

• PCR amplification
• DNA sequencing
• Chromatography method

• Gel electrophoresis
