Question

Which statement is false about the genome of prokaryotes? It may contain other DNA elements besides its chromosome. It contains exons and introns. It is circular. Unlike most eukaryotes it consists almost entirely of coding DNA. Some of the DNA of bacteria replicate separately from the chromosome which enzyme is the primarily responsible for DNA replication? DNA polymerase I DNA polymerase III Okasaki synthetase helicase Which statement below provides an explanation of why a lagging strand (rather than two leading strands exists during DNA replication? New nucleotides can be added only to a 3' (-OH) end. Only one primer can exist at a time. There is only one DNA polymerase per cell There is only one replisome per cell Which enzyme is responsible for unwinding DNA in prokaryotic replication? DNA polymerase III primase helicase gyrase The resistance to antibiotics in bacteria is the result of Mutation of a bacterial gene Change in the manufacture of the antibiotics Special enzymatic capability of genes in the genome called bacteriocidens The presence of non-chromosomal R-plasmids What statement is false about the chromosome of Escherichia coli? 40% of predicted proteins are of unknown function. Map distances of the genes are given in minutes. Operons are equally distributed on both strands. The chromosome has 4.5 Kbytes. Unlike eukaryotes, genes encoding enzymes of a single biochemical pathway are clustere statement is accurate about reproduction in bacteria? Growth is measured by the time it takes one bacterial cell to make two cells. Generation time is defined the time required for a population of microbial cells to Growth in bacteria and archaea involves a modified version of meiosis, "semi-meiosis". During the death phase of bacterial growth curve no growth is occurring.

Explanation / Answer

Answers :

Question number 1: The statement which is wrong among all the statement is B (It contains exons and introns).

Explanation : Prokaryotes contains plasmid DNA other than the chromosomal DNA that replicates independent of chromosomal DNA. Both plasmid and chromosomal are circular in nature. in fact introns which are the non coding sequeences are found only in eukaryotes.

Question number 2 : The correct answer is B ( DNA polymerase III)

Explanation : DNA polymerase III is the prime DNA synthesising enzyme in eukaryotes which is the component of replisome, which is located at the replication fork. It has high processesivity and polymerising rate which made Pol III as primary DNA replication enzyme. DNA polymerase is mainly concerned with DNA repair and helicase enzyme is involved in DNA denaturation during replication.
