DNA. CHROMOSOME THEORY OF HEREDITY

According to the chromosome theory of heredity, what determines the continuity of properties in a series of generations?

• Proteins in the cytoplasm

• Mitochondria in the cell

• Chromosomes in the nucleus

• Ribosomes in the endoplasmic reticulum

What is the carrier of hereditary information?

• RNA

• DNA

• Proteins

• Carbohydrates

Where is most of the DNA found in a cell?

• Cytoplasm

• Nucleus

• Mitochondria

• Ribosomes

What is the structure of a DNA molecule?

• A single poly-nucleotide chain

• Two poly-nucleotide chains twisted into a spiral

• A double helix made of amino acids

• A random arrangement of nucleotides

How is the genetic code represented in DNA?

• Through the arrangement of nucleotides

• Through the arrangement of proteins

• Through the arrangement of chromosomes

• Through the arrangement of mitochondria

Autosomal DNA is inherited from both parents and can be used to trace either side of the family.

• True

• False

The mtDNA test is used to trace your father's side of the family.

• True

• False

DNA is accurately reproduced in cell division, which ensures the transfer of hereditary traits and specific forms of metabolism in a series of generations of cells and organisms.

• True

• False

The Y-DNA test can only be taken by males.

• True

• False

Because a father passes mtDNA to both male and female children, both men and women can get value from this test.

• true

• false
