Genes for medically important proteins can be cloned and inserted into bacteria.
Why can bacteria recognize a human gene and then produce a human protein?
DNA replication in bacteria and humans is the same.
Bacterial cells contain the same organelles as human cells.
Bacterial cells and human cells contain the same kind of chromosomes.
The basic components of DNA are the same in humans and bacteria.
How does the process of DNA replication impact mutations in an individual?
Since replication keeps the old strands as templates mutations may be carried into future strands.
Replication only produces new DNA strands so the old stand with the mutation is destroyed.
Mutations are often lost since the cell will die during the replication process if the DNA is mutated.
All DNA replication stops when there is a mutation so the mutation won't hurt the individual.
Which of the following segments would pass on a mutation?
1
2
3
4
