BIOLOGY 101 Cell Division Gizmos Student Exploration: Cell Division Vocabulary: cell division, centriole, centromere, chromatid, chromatin, chromosome, cytokinesis, DNA, interphase, mitosis Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Cells reproduce by splitting in half, a process called cell division. What do cells need to do between divisions to make sure that they don’t just get smaller and smaller? In between cell division the cells go through the interphase stag...

When the organism expresses a set of genes, the result is the characteristics of that organism. These characteristics are called its ____________. Phenotype The term "transcription" means the process of reading a base sequence in ____________ to generate a complementary base sequence in ____________. DNA RNA Information from DNA is transcribed into mRNA, which is then transported to ribosomes. This phrase describes the role of ____________ in ____________ expression. Life Informat...

A computer virus is a program that can copy itself and infect a computer without the permission of the owner. How do you think a computer virus compares to a real virus? A computer Virus and a real virus are very similar bec...

Interspecific competition is defined as The functional role of a species within its habitat is referred to as its Species of warblers (birds) living in the same general region minimize their interspecific competition by A good example of commensalism would be the relationship between In the minds of design theorists, separate clades (large groups) derive from Studying competition between the Peaks of Otter salamander and the Eastern Redback salamander would be an example of studying ecology at t...

Student Exploration: Human Karyotyping Vocabulary: autosome, chromosomal disorder, chromosome, karyotype, sex chromosome Prior Knowledge Question (Do this BEFORE using the Gizmo.) A chromosome is a rod-shaped structure made of coils of DNA. Most human cells have 23 pairs of chromosomes. 1. Why do you think humans have two sets of 23 chromosomes? (Hint: Where did each set come from?) 2. How do you think different people’s chromosomes would compare? Gizmo Warm-up Scientists use to study the chro...
