Order of Heredity

A student lists facts about chromosomes and genes.

Bases on the information, which statement is correct?

• DNA is made of chromosomes.

• Chromosomes contain genes.

• Genes are made of chromosomes but not DNA.

• Chromosomes contain genes but not DNA.

The diagram shows two important components of heredity.

Which labels will complete the diagram correctly?

• 1: gene; 2: chromosome

• 1: nucleus; 2: DNA

• 1: gene; 2: nucleus

• 1: DNA; 2: chromosome

How do children inherit traits from their parents?

• Children receive chromosomes that carry genes from certain traits from both parents.

• Children receive chromosomes that carry genes from certain traits from one parent.

• Children receive genes that carry chromosomes for certain traits from both parents.

• 1. Children receive genes that carry chromosomes for certain traits from one parent.

The diagram represents the role of genetic material in an organism, with two structures labeled A and B

Why do structures A and B lead to the expression of different characteristics in an individual?

• because they have different sizes

• because they have different DNA sequences

• because they produce the same type of proteins

• because they are present at different locations on a chromosome

Examine the diagram

What can be concluded from the diagram?

• Each gene codes for the same protein.

• Different genes code for different proteins.

• The bacterium uses proteins to edit DNA

• Proteins are recycled to form DNA

Which of the following best

describes the role chromosomes play in the inheritance of traits?

• Chromosomes produce the proteins that determine traits which are then passed on to offspring.

• Chromosomes act as the building blocks of DNA used to pass on the genes during reproduction.

• Chromosomes prevent the mixing of genetic information to reduce the chances of mutation in offspring.

• Chromosomes package and organize DNA, ensuring that they are correctly passed on duringreproduction.

Which of the following nitrogen base pair codes with adenine?

• nitrosine

• thymine

• cytosine

• guanine

Which of the following statements best describes the chromosome pictured?

• The chromosome is composed of several genes that code for the same protein.

• The chromosome is composed of several genes that code for different proteins.

• The chromosome is composed of the same genes that code for the same protein.

• The chromosome is composed of the same genes that code for different proteins.

Which of the following nitrogen base pair codes with cytosine?

• nitrosine

• adenine

• thymine

• guanine

Which statement best explains how genes and chromosomes function together in an organism’s nucleus to pass traits to offspring?

• Genes are made of chromosomes which hold instructions for building DNA for a unique trait.

• Genes produce chromosomes that hold information to build traits by duplicating the DNA passed to offspring.

• Genes are segments of DNA on a chromosome that hold information to build unique traits passed to offspring.

• Genes enter the nucleus of a cell to activate segments of DNA on a chromosome to produce unique traits.
