Front

The ____________ of the protein will determine the function that protein will have inside the body.

Back

Shape and size

Which statement best describes the work environment that biotech scientist teams work in? Options: They are out in the field where the disease is most likely to hit the farmer's soybean plants. They work with the plant's DNA in test tubes in a lab. They grow individual soybean cells that have been genetically changed and study each cell under a microscope. All their work is done with computers and robots.

Front

What is the termination sequence?

Back

Signals where the gene finishes copying and prevents the cell from reading the next gene on the chromosome.

Front

The Biotech team has discovered a transgene that is successful in defending against SDS. (Sudden Death Syndrome in Soybeans) If they would like to change the amino acid sequence of the protein, then they should…

Back

use a different coding region

Front

Where did the Biotech team, the transgene designer, find the gene that will defend soybean plants from the SDS pathogen?

Back

A scientist in his group discovered that a model plant called Arabidopsis could resist the SDS pathogen. The gene could be transferred from Arabidopsis to soybean.

Front

How would a geneticist obtain many copies of the promoter and the coding region?

Back

They can use PCR to make copies of the desired gene regions from the original DNA of the organism.

Front

A geneticist designs a transgene with a coding region that fights SDS, but selects a promoter that causes the gene to be expressed ONLY in the seed. What will be the outcome?

Back

This will not be a good result since the soil fungi that causes SDS attacks at the roots, then effects the stems and leaves...but not the seed.

Front

RNA moves through the ribosome where it is

Back

Used as instructions to build a protein.

Front

What transgene modification might help if the plant does not make enough of the protein that fights SDS? Options: use a different promoter, use a completely different coding region, use a bigger gene, use a gene with a slightly different coding region

Back

use a different promoter

Front

Which correctly describes the order presented in the basics of DNA?

Back

Amino acids make up proteins which make up living cells which make up tissue which make up organs
