TCA CYCLE QUIZ

cut DNAs producing a blunt end

protect bacteria from viral infection

All of these

cut DNA in a staggered fashion

Random mating

Small population size

Active migration between groups

Selection for homozygotes

Protein-coding genes are always associated with a restriction pattern

Restriction sites allow DNAs to be digested

None of these

Known protein coding sequences are too far apart to allow linkage determination for most new genes

MPO

RP13

GLUT4

DCP1

Down's syndrome

Cystic fibrosis

Muscular dystrophy

Cri du Chat

Mutation is increased

They tend to loose genetic diversity

There is an increased incidence of recessive diseases

Alleles may become fixed

Cystic Fibrosis

Down's syndrome

Sickle cell anemia

All of these

bind oligo-dT, treat with reverse transcriptase, digest with RNase, add G residues to the 3' end, bind oligo-dC, treat with DNA polymerase

digest with RNase, add G residues to the 3' end, treat with reverse transcriptase, add G residues to the 3' end and treat with DNA polymerase

treat with reverse transcriptase, digest with RNase, add G residues to the 3' end, bind oligo-dC, treat with DNA polymerase and bind oligo-dT

bind oligo-dC, treat with reverse transcriptase, digest with RNase, add G residues to the 3' end, bind oligo-dT and treat with DNA polymerase

restriction fragments

sticky ends

single strands

ligases

have identical DNA sequences

originate from the same type of cell

be cut by the same restriction enzyme

be of the same length
