Part 1 - Chapter 3 (Inquisitive)

Drag and drop the nitrogen base to its complement in the section of DNA below.

- T - G - C

Match the following bases to their complement base. - thymine (T) - cytosine (C)

- adenine - guanine

In mammals, _________ have two X chromosomes, and ______ have one X and one Y chromosome.

- females - males

Match the term to its definition. - the condition in which two alleles at a single locus on homologous chromosomes are different - the condition in which two alleles at a single locus on homologous chromosomes are the same

- heterozygous - homozygous

Match the process to the cells that are reproduced. - gametes - somatic cells

- meiosis - mitosis

Match the term to the correct definition. - the exchange of genetic material between homologous chromosomes, resulting from a cross-over event - the failure of the chromosomes to properly segregate during meiosis, creating some gametes with abnormal numbers of chromosomes - rearrangement of chromosomes due to the insertion of genetic material from one chromosome to another

- recombination - nondisjunction - translocation

Click on the two alleles in the image that are most likely to be inherited together.

A & B

Which of the following statements are correct about the functions of proteins in the body?

Correct Statement(s) About Protein Functions: - Some proteins are enzymes that unzip DNA during replication. - Some proteins are hormones that regulate metabolic activities throughout the whole body. - Some proteins are responsible for the function, repair, and growth of your hair. - Some proteins are enzymes that break down lactose in milk products so you can digest them. - Some proteins are responsible for how bone is shaped. Incorrect Statement(s) About Protein Functions: - Calcium is a protein used to determine how bone is shaped. - Biotin determines hair growth.

Which of the following examples could potentially lead to epigenetic effects?

Could Lead to Epigenetic Effects: - A mother's physical activity habits early in life can impact the life-long health of her then unborn child. - A mother is exposed to pollution that affects a developing fetus. - A mother living in an extremely cold environment can affect the growth and development patterns of her grandchildren. Could Not Lead to Epigenetic Effects: - A mother passes her genes on to her child.

Arrange the images in their correct order.

Screenshot 5

If the genetic code is transmitted from parents to offspring via two gametes, then which is true?

The offspring's genetic code contains one chromosome from each pair of homologous chromosomes in a parent's genome.

What are these structures called? Drag and drop the appropriate name to the picture.

chromosome

What type of cell is the product of mitosis? Drag and drop your answer to the picture.

diploid

Genes that are close together on a chromosome are much more likely to recombine with one another than genes that are farther away from one another.

false

What is the scientific name for the photograph below, which depicts a person's chromosomes?

karyotype

Aside from the nucleus, where else can a small amount of DNA be found in a eukaryotic cell?

mitochondria

In mammals, the male parent's gamete determines the sex of the offspring.

true
