Question
Chapter 15.4, Problem 3MC
Summary Introduction
To determine:
The four groups of species in the hominin family tree, and also to determine the species that is still alive.
Concept introduction:
Hominins refer to humans and their extinct ancestors. They differed from other primates in walking straight on two legs, a process called bipedalism. They had adaptation such as longer and stronger legs and shorter arms for bipedalism unlike other groups of primates.

8. Transcription and Translation Practice: (Video 10-1 and 10-2)
A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense
DNA strand and label the 5' and 3' ends.
B. Use the antisense strand that you create in part A as a template to create the mRNA
transcript of the gene and label the 5' and 3' ends.
C. Translate the mRNA you produced in part B into the polypeptide sequence making sure
to follow all the rules of translation.

What is the structure and function of Eukaryotic cells, including their organelles? How are Eukaryotic cells different than Prokaryotic cells, in terms of evolution which form of the cell might have came first? How do Eukaryotic cells become malignant (cancerous)?
What are the roles of DNA and proteins inside of the cell? What are the building blocks or molecular components of the DNA and proteins? How are proteins produced within the cell? What connection is there between DNA, proteins, and the cell cycle? What is the relationship between DNA, proteins, and Cancer?
