To get around this problem, you decide to use a specialized application of DNA replication, called the polymerase chain reaction (PCR). In PCR, DNA is isolated from skin cells, a blood smear, or even a few hairs and subjected to repeated rounds of replication. Not all the DNA is copied, only those unique target sequences that can be used for identification are replicated. With each round, the number of copies of target DNA doubles. For these questions, assume that there was only 1 copy of target in the initial sample of DNA. How many copies would there be after one round of PCR

Living cells cannot use heat to provide the activation energy for biochemical reactions because which choice(s) complete the sentence correctly? a) answer choice ii. eliminate b) answer choices ii and iv. c) answer choice iii and iv. d) all answers can complete the sentence.

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.

To determine if a particular plant is homozygous or heterozygous, you would have to test cross with a
