 analyzing DNA by gel electrophoresis allows researchers to | identify similarities and differences in the genomes of different kids of organisms |
| PCR : copies of DNA segments :: | DNA plasmid : gel electrophoresis |
| An error in DNA replication can cause | mutation cancer genetic variation |
| one function of gel electrophoresis is to | separate DNA fragments |
| what is not a gene mutations | deletion |
| a genome is | an organisms collection of genes |
| what is never a frameshift mutation | substitution |
| the use of genetic engineering to transfer human genes into bacterial | allows the bacteria to produce human proteins |
| PCR and DNA replication | require the same ingredients to make copies of DNA |
| on an electrophoresis gel, band B is closer to the positive end of the gel that is band A. What is true? | the DNA fragments in band B were smalled than those in band A |
| a mutation that involves one or a few nucleotides is called a | point mutation |
| DNA fingerprinting has been used i ncriminal investigations because | DNA found on murder weapons is easy to identify |
| to make many copies of a fragment of DNA or a genome | cloning |
| a ---------- can be clones so that it can be sequences and analyzed towards the goal of finding a cure | defective gene |
| -----------can also lead to developing an entire organism | cloning |
| useful quantities for valuable proteins can be used genetically engineered into ------------- and ------------- | bacteria and yeast |
| --------------, ---------------, -----------------, and some -------------------- can act as cell factories | bacteria, molds, yeasts, and some animals |
| some ------------ are genetically modified | foods |
| some ------------- is modified with a gene that acts to kill caterpillars | corn |
| some plants have genes that allow them to withstand --------------- | herbicides |
| using ---- scientists can study specific region of chromosomes where individuals DNA sequences differ and amplify or make copies of them | PCR |
| --------------------------------------- can b used to show the differences between individuals and displayed as a banding pattern | gel electrophoresis |
| DNA that is recovered from ------------------ is often in very small amounts | crime scenes |
| PCR | polymerase chain reaction |
