DNA Structure and Replication Which of the following is used to determine the appropriate stringency (Wallace rule)? Tm = 4 x (No.of A:T base pair) + 2 x (No.of G:C base pair) Tm = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) Tm = 69.3° + 0.41 (%)G+C -650/1 Tm = 4 x (No.of G:C base pair) + 2 x (No.of A:T base pair) Tm = 4 x (No.of A:T base pair) + 2 x (No.of G:C base pair) Tm = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) Tm = 69.3° + 0.41 (%)G+C -650/1 Tm = 4 x (No.of G:C base pair) + 2 x (No.of A:T base pair) ANSWER DOWNLOAD EXAMIANS APP
DNA Structure and Replication In a typical electrophoresis experiment, larger fragments of DNA move more quickly, so they appear nearer the top of a gel photograph slowly, so they appear nearer the bottom of a gel photograph quickly, so they appear nearer the bottom of a gel photograph slowly, so they appear nearer the top of a gel photograph quickly, so they appear nearer the top of a gel photograph slowly, so they appear nearer the bottom of a gel photograph quickly, so they appear nearer the bottom of a gel photograph slowly, so they appear nearer the top of a gel photograph ANSWER DOWNLOAD EXAMIANS APP
DNA Structure and Replication Automated DNA sequencing uses the chain termination method with no primer either (b) or (c) but with a polynucleotide primer labeled with a fluorescent dye but with an oligonucleotide primer labeled with a fluorescent dye with no primer either (b) or (c) but with a polynucleotide primer labeled with a fluorescent dye but with an oligonucleotide primer labeled with a fluorescent dye ANSWER DOWNLOAD EXAMIANS APP
DNA Structure and Replication One hypothesis of DNA replication suggested that the parental DNA molecules are broken into fragments. Both strands of DNA in each of the daughter molecules are made up of an assortment of parental and new DNA. This statement refers to which hypothesis?

DNA Structure and Replication In the study of one experiment it was found that the value of Tm for DNA is = 40° C. If the cell has 20% GC at the above Tm, then what will be value of 'Tm' if the GC% increases to 60%? Remains same Increases Can not be compared Decreases Remains same Increases Can not be compared Decreases ANSWER DOWNLOAD EXAMIANS APP
DNA Structure and Replication What does ligase do during replication of DNA? Joins nicks in DNA strands Digests mRNA when it is no longer needed Synthesizes the lagging strand Makes copies of mRNA from DNA Joins nicks in DNA strands Digests mRNA when it is no longer needed Synthesizes the lagging strand Makes copies of mRNA from DNA ANSWER DOWNLOAD EXAMIANS APP
