SC.7.L.16.1

The nucleus contains the cells genetic material in the form of DNA. DNA is organized into our chromosomes, which are made up of thousands of ________ that determine our traits

• RNA

• cells

• gametes

• genes

Our traits are determined by our genes and these traits are inherited. Where do our genes come from?

• our father

• our mother

• from both parents equally

• part from our mother but mostly from our father

This cell is getting ready to divide. The instructions to form another cell are inside the_________, which are found in the nucleus

• chromosomes

• nucleolus

• nucleoplasm

• ribosomes

Information about traits is stored in the cell nucleus in a molecule called ______

• DNA

• ATP

• cytoplasm

• the nucleus

A segment of DNA that codes for the ability to make one type of protein molecule is known as a(n)____________________

• axon

• codon

• gene

• intron

Chromosomes, which contain DNA, have several functions. All BUT ONE of these statements is a function of chromosomes

• Chromosomes determine the traits of an organism

• Chromosomes provide instructions to make proteins

• Chromosomes determine the gender of an individual

• Chromosomes help an organism produce usable energy

This is the karyotype of a child with a genetically inherited condition called Klinefelter's syndrome. Review the chromosomes of the child. Predict how the child may have ended up with Klinefelter's syndrome

• The karyotype shows an extra X chromosome that could have been inherited either parent

• The karyotype shows an extra X chromosome that must have been inherited from the mother

• The karyotype shows an extra chromosome that is the result of a genetic mutation, called substitution

• The condition is caused by mutagens in the child's environment resulting in a change in chromosome number

Things like your eye color and height are not traits you can control. In fact, you inherit traits like these from your parents. These traits are passed on because they are controlled by ____________

• LNA

• genes

• hormones

• tradition

Where are chromosomes found in an animal cell?

• inside a gene

• in the cytoplasm

• in a strand of DNA

• inside of the nucleus

During cell division, or mitosis, an exact duplicate of the original cell is produced. The instructions for cell division are found in the __________ in the __________

• nucleus:RNA

• chromosomes:nucleus

• nucleus:nucleolus

• ribosomes:RNA
