Biotechnology | Lesson 9

Question 1

Transcription

Answer 1

Creating RNA from DNA

Question 2

Translation

Answer 2

Use RNA from DNA

Question 3

DNA vs. RNA

Answer 3

DNA: A-T, C-G, bonded w/ hydrogen bond
RNA: A-U, T-A, C-G, copy of DNA

Question 4

Protein Creation (promoter sequence, terminator)

Answer 4

Enzyme read DNA. Promoter sequence tell when germ starts.Terminator @ end. Transcribes into RNA match. Move RNA to cytoplasm to make proteins. RNA translated to amino acid sequence = protein

Question 5

Chromosomes

Answer 5

DNA → coils around proteins → coiled into supercoils → coiled into chromosomes

Question 6

Gene gun

Answer 6

Gene placed on gold shard and shot into plant

Question 7

Agrobacterium

Answer 7

Bacteria take part of plant chromosome + insert DNA to make sick. Replace circular plasmid

Question 8

Round up ready plants resistant to

Answer 8

Glyphosate

Question 9

Bt

Answer 9

Genetically make plants larval bug resistant (started with corn)

Question 10

Problems with RR

Answer 10

Can easily spread to other plants which can make weeds resistant

Question 11

Problems with Bt

Answer 11

Can’t rotate pesticide so bugs become resistant

Question 12

Horticulture: “moon” series, blue roses

Answer 12

• Pansy + petunia - lavender

* Hybrid tea rose
