Question

Genetically engineered pork has a higher flesh-to-bone ratio. Which of the following sentences explains how pork is genetically engineered?
) the desired gene is inserted into the genomes of the pork. B.) all the genes in the genome of the pork are changed. C.) the desired gene is inserted in the plasmids of the pork.

Answer 1

A, the desired gene is inserted into the genomes of the pork. If all the genes in the genome of the pork are changed, the cells will not make the correct proteins and they may die. Plasmids are junk DNA, so it would serve no purpose. Besides, Plasmids are in bacteria, not in the Eukaryotic cells.

Answer 2

I agree with your answer.

I did however find this article:

Answer 3

Fascinating. I have only been taking Microbiology this semester so I am far from an expert on the subject.

Answer 4

plasmids aren't junk DNA lol

Answer 5

Junk DNA in a sense. But yes you're right. Plasmids are non-essential for the survival of the cell, but can provide extra benefits.

Answer 6

lol they're not junk DNA, i don't know where you got this idea.
Plasmids CAN be essential for the survival of a cell, if for instance, the plasmid codes for a gene that results in a protein whose action inactivates a certain antibacterial agent and so it able to survive in a medium containing the antibacterial agent.

Answer 7

Determine the significance of plasmids for bacteria. A.)they help in meiosis and in the manipulation of the plasmids of their host organisms. B.) they help in mitosis and in the manipulation of their genome with the gene of their requirment. C.) they help in reproduction, antibiotic resistance, virulence and competition with other bacteria.

@shaymustache24

If you read aaronq's last comment,
you'll see that your answer's right there.

Answer 9

is it a?

Answer 10

Nope.

When bacteria reproduce, they pass their plasmids onto their offspring.

So, pretend there's a bacterium whose plasmid protects it from antibiotics.
When that bacterium reproduces,
its offspring will ALSO have the plasmid that protects it from antibiotics.

All of the bacteria who DON'T have this special plasmid will die.

But the ones that DO have it will live,
reproduce,
and create other bacteria with special plasmids just like theirs.

Answer 11

so c

Answer 12

Yes. Wonderful.

Answer 13

thanks :)

Answer 14

Thanks for clarifying that. I have heard it compared to 'junk DNA' several times, but you are right in that many actually do need it. A lot of the time it is used for specialized functions (like glowing in the dark for example) that isn't necessary for regular metabolic functions. It IS, like you said, more for survival.

Answer 15

NOT C

Answer 16
