Match the specific cloning vectors with their features in ad
Solution
Answer :
Q56:
Polylinker: Region of DNA with many restriction enzyme sites
Copy number : is how many molecules of DNA found in the cell
Antibiotic resistance gene: Means to select for the cells that received the vector
Alpha complementation: method to determine if foreign DNA has been inserted into the lacZ gene
Q57:
Shuttle vectors: viral genomes with many genes removed so that foreign DNA can be inserted packaged
Bacteriophage vectors: A series of vectors containing large pieces of DNA that can be used to sequence an entire genome
Cosmids: vectors containing only viral cos sites plus foreign DNA
Artificial chromosomes: Contains origin of replication for two organisms and can be transferred back and forth
Q 58:
DNA polymerase: Processively adds a complementary nucleotide to 3’ end of a new strand of DNA
DNA ligase : Links the 3’-Oh to the 5’-Po4 forming the phosphodiester bridge
DNA gyrase : Untwists strands of DNA
Single stranded binding protein: Keeps the two complementary strands of DNA separated
Primase: RNA polymerase used to synthesize short RNA primers
Q59:
Origin of replication: Specific AT rich sequence where replication begins
Okazaki fragments: Small pieces of DNA on the lagging strand of DNA
Semi-conservative: Each new molecule consists of one completely new strand and one completely old strand
Replisome: Overall complex of proteins involved in replication
Telomeres: special structures found at the end of eukaryotic chromosomes
