genomes?
LO: SWBAT explain how scientists use biotechnology to manipulate organisms
DN: Using your knowledge of prefixes and suffixes, what do you think biotechnology is?
HW: red review book- photosynthesis (due Monday)
What is biotechnology?
The use of ___________ to perform practical tasks for ________.
Yeast, helps us make bread & wine.
Bacteria, help us make yogurt & cheese.
organismshumans
What is a genome?
Complete set of an organism’s_________ material.
The Chromosomes, DNA, & theGenes which are all found in the
________.
genetic
nucleus
What is a Gene?
A gene is a sequence of ____ on a ___________ that codes for one ________.**Remember, not all of the ____ codes for proteins. The parts that do are called ______, the parts that don’t are called ___________________.
DNAchromosomeprotein
DNA
genesnon-coding regions
What is DNA Technology?The branch of biotechnology where
scientists actually ___________ (alter) the ________ of organisms at the
molecular level.
manipulategenomes
Why would altering DNA affect our characteristics/traits?
DNA codes for the _________ that determine our _______.
proteinstraits
What are some examples of DNA Technology?
CloningDNA Fingerprinting
RecombinantDNA GMO
Scientists often use __________ ________ in DNA Technology
How do bacteria reproduce?
Asexual Reproduction
Does that lead to variation inoffspring?
No, it leads to clones
bacteria &viruses
Human Genome Project
Scientists studied and mapped the human _________ (determined the entire ____________ sequence of DNA). genomenucleotide
Steps of the Human Genome Project:
1)Sequence the DNA (order of the bases).
2)Regions of DNA that code for proteins (genes) must be distinguished from non-coding regions.
3) The functions of the resulting proteins must be determined.
4) Develop a map of the human genome.
Why is this so important?1)Comparing human sequences with
those from other species provide insight into _____________ relationships.
2)Identifying genes will aid in ____________, ___________________ common ailments.
