DNA, Chromosomes, RNA and Genes

What are chromosomes?

• Double-stranded molecules of DNA, tightly coiled together

• Single-stranded molecules of DNA, tightly coiled together

• Complete set of an organism's DNA

• Segments of DNA that code for proteins

What is the difference between a gene and a genome?

• A gene is found in the nucleus, while a genome is found in the cytoplasm

• A gene codes for proteins, while a genome codes for traits

• A gene is a segment of DNA, while a genome is an organism's complete set of DNA

• A gene is an organism's complete set of DNA, while a genome is a segment of DNA

What does DNA look like?

• Double-stranded molecule

• Circular molecule

• Triple-stranded molecule

• Single-stranded molecule

Where are chromosomes found in a cell?

• Cytoplasm

• Nucleus

• Mitochondria

• Cell Membrane

How are RNA and DNA similar?

• Both are found in the cytoplasm

• Both are single-stranded molecules

• Both are double-stranded molecules

• Both are made up of similar nucleotides

What is the main function of RNA?

• Building proteins using the DNA code

• Determining traits from the DNA code

• Producing DNA

• Building chromosomes from DNA

How are RNA and DNA different?

• RNA is single-stranded, while DNA is double-stranded

• RNA contains Thymine while DNA contains Uracil

• RNA codes for traits, while DNA codes for proteins

• RNA is found in the nucleus, while DNA is found in the cytoplasm

What are the three parts that make up a DNA nucleotide?

• Deoxyribose sugar, amino acid, and phosphate group

• Deoxyribose sugar, nitrogenous base, and phosphate group

• Ribose sugar, amino acid, and phosphate group

• Ribose sugar, nitrogenous base, and phosphate group

What are the base pairing rules in RNA?

• A - C and G - T

• A - U and C - G

• A - T and C - G

• A - G and C - T

What are proteins?

• Building blocks of DNA

• Building blocks of RNA

• Segments of DNA that code for traits

• Chains of amino acids
