Question

To clone an animal by embryo splitting, _. There must be two host animals and two fertilized eggs A fertilized egg is collected from a donor mother and implanted into a host animal An egg is fertilized by in vivo fertilization and remains in the host animal to mature An embryo must be in a blastocyst stage in the host animals while the splitting takes place An unfertilized egg is collected from a donor mother and then fertilized in a dish by in vitro fertilization A collection of clones containing all the DNA sequences carried by an individual is called a genomic library, True False An advantage of YAC_s over other vectors in cloning human genes is that they _. are taken up more readily by recipient cells have a higher capacity for carrying long DNA fragments are less likely to trigger cell rejection resemble a human chromosome more closely than do other vectors carry long regions of human-like DNA in a typical application, a microarray is used to compare the _. expression of genes in two different tissues alleles of each chromosome length of DNA fragments in yeast vectors changes in gene sequences within an allele through generations of a single-family protein products produced when using different DNA sequencing techniques During the denaturation step of PCR, _ bonds are broken when DNA is heated. hydrogen double-stranded ionic metallic covalent

Explanation / Answer

4. To clone an animal by embryo splitting, an embryo must be in blastmere stage in the host animals while the splitting takes place.

6. An advantage of YACs over other vectors in cloning human gene is that they resemble a human chromosome more closely than do other vectors.

7. In a typical application, a microarray is used to compare the expression of the genes in two different tissues.
