Shared Functions, Shared Genes

Shared Functions, Shared Genes

By Sara Schechter

Guiding Question: If organisms build proteins the same way, do they build the same proteins?

On the next slide, you will watch a video clip. As you watch, consider the biochemical similarities of all living things.

Provide an example of how diverse life forms are similar at the molecular level.

Multiple Choice

Similarities between organisms are coded for by the same genes.

• True

• False

Multiple Choice

All living things are made of the same molecules.

• True

• False

Multiple Choice

The same molecules (proteins that make ATP, ATP itself, enzymes, etc) carry out the same functions for all living things.

• True

• False

Multiple Choice

All organisms have some genes in common.

• True

• False

Multiple Choice

A core set of about 300 genes underlie the basic biochemical components and functions for all living things. We can reason that these genes were present in an ancestral life form.

• True

• False
