ANSC446 Test Questions with 100% Correct
Answers
The primary chemical structure of a double-stranded DNA includes:
phosphodiester linkage in deoxyribose backbone
Nucleotides are monomers of DNA. What does each nucleotide consist of?
a purine or pyrimidine base, a phosphate group, and deoxyribose
The most impossible molecule for the long-term storage of genetic information is
DNA
What is not true about DNA replication?
DNA ligase works the same way as DNA polymerase I to add dNTP to the new strand
Which is not a part of post-transitional process in eukaryotes
binding of transcription factors to the promoter sequence
DNA promoter is defined as:
a specific DNA sequence located at 5' flanking region of a gene and interactive with RNA
polymerase or transcription factor
To clone the insulin cDNA sequence into a plasmid at the Hind III restriction enzyme site (
AAGCTT), you will need to cut plasmid with Bam HI and to prepare the insulin cDNA
with the necessary complementary ends to Hind III sequence. Will this approach work in
the lab?
no
