Gene Chromosome Theory and DNA

Arrange the following structures from smallest to largest: chromosome, nucleus, cell, gene

• chromosome, nucleus, cell, gene

• gene, chromosome, nucleus, cell

• gene, cell, nucleus, chromosome

• chromosome, gene, cell, nucleus

DNA is stored inside the

• ribosomes, which have chromosomes that contain genes

• nucleus, which has chromosomes that contain genes

• ribosomes, which have genes that contain chromosomes

• nucleus, which has genes that contain chromosomes

DNA is made up of

• folded chains of glucose molecules

• four types of bases (A,T, C,G)

• complex energy rich molecules

• 20 different kinds of amino acids

Explain the relationship between chromosomes, genes and nuclei

• Genes are found in nuclei. Nuclei are found in chromosomes

• Chromosomes are found on genes. Genes are found in nuclei.

• Chromosomes are found in nuclei. Nuclei are found in genes.

• Genes are found on chromosomes. Chromosomes are found in nuclei.

Which is true about the number of genes and number of chromosomes in a human body cell?

• There are more genes than chromosomes in body cells.

• There are more chromosomes than genes in body cells.

• There are equal numbers of genes and chromosomes in body cells.

If a set of instructions that determines all of the characteristics of an organism is compared to a book and a chromosome is compared to a chapter in the book, then what would be compared to a paragraph in the book?

• an egg

• an amino acid

• a DNA molecule

• a starch molecule

What determines the kind of genes an organism possesses?

• sequence of the subunits A,T,C and G in the DNA of the organism

• type of amino acids in the cells of the organism

• size of simple sugar molecules in the organs of the organism

• shape of the protein molecules in the organelles of the organism

The genetic code of a DNA molecule is determined by a specific sequence of

• chemical bonds

• sugar molecules

• ATP molecules

• molecular bases

What is true about the sequence of bases found in DNA?

• It changes every time it replicates.

• It determines the characteristics that will be inherited.

• It directly controls the synthesis of starch within a cell.

• It is exactly the same in all organisms.

The instructions for the traits of an organism are coded in the arrangement of

• bases in DNA in the nucleus

• fat molecules in the cell membrane

• glucose units in carbohydrate molecules

• energy-rich bonds in starch molecules
