Understanding Cell Genomes and Chromosomes

What is the complete set of DNA in a cell called?

• Chromosome

• Genome

• Plasmid

• Nucleoid

In prokaryotes, the genome is typically composed of:

• Multiple linear DNA molecules

• A single, double-stranded DNA molecule in a loop

• RNA molecules

• Protein complexes

What is the region called where the genetic material is located in prokaryotic cells?

• Nucleus

• Nucleoid

• Chromosome

• Plasmid

What are the smaller loops of DNA found in some prokaryotes that are not essential for normal growth?

• Chromosomes

• Nucleoids

• Plasmids

• Ribosomes

In eukaryotes, the genome is organized into structures called:

• Nucleoids

• Plasmids

• Chromosomes

• Ribosomes

How many chromosomes do human somatic cells contain?

• 23

• 46

• 92

• 12

What term describes a cell containing two matched sets of chromosomes?

• Haploid

• Diploid

• Polyploid

• Aneuploid

• A double set of chromosomes

• A single set of chromosomes

• The number of genes

• The number of nucleotides

Which of the following is true about eukaryotic chromosomes?

• They are circular and found in the nucleoid.

• They are linear and bound with proteins.

• They are composed of RNA.

• They are not essential for cell growth.

What is the characteristic number of chromosomes in the nuclei of eukaryotic cells called?
