[" 158.DNA replication in bacteria occurs: "],[" (1) Within nucleolus "],[" (2) Prior to fission "],[" (3) Just before transcription "],[" (4) During S phase "]

True or False DNA synthesis occurs during S-phase.

The death of donor bacteria occur during Conjugation Transformation Transduction 2 & 3

Match the following {:("List - I","List - II"),("(A) Replication","(1) formation of RNA from DNA"),("(B) Transcription","(2) synthesis of copy of DNA"),("(C ) Translation","(3) single strand of DNA"),("(D) Template","(4) synthesis of proteins by RNA"):} Now, correct match is

Assertion: In plant cells, during S-phase, DNA replication begins in the nucleus, and the centriole duplicates in the cytoplasm. Reason: If the initial amount of DNA is denoted as 2n in G_(1) even after S-phase the amount of DNA remains the same i.e., 2n.

LH surge occurs during phase of menstrual cycle (a) Menstrual phase (b) Beginning of proliferation phase (c) Just before end of proliferation phase (d) At the middle of the cycle

DNA replication occurs during Or The replication of centrioles occurs during Or G_(1),G_(2) and S phaes are seen in which phase of the cell cycle

Which one among the following is correct ? (A) Duration of interphase is short as compared to M- phase (B) DNA content becomes double during M-phase (C) DNA replication occurs in S- phase (D) Mitotic phase occurs in bacteriophage

How many of the following statement are TRUE ? (i) 6 turns of B - DNA has 120 nucleotides. (ii) In prokaryotes , gene regulation generally occurs at transcriptional level. (iii) Operon concept was given by Jacob and Monod while working on yeast. (iv) The enzyme required for peptide chain synthesis is a ribozyme in bacteria and lies in 50S subunit. (v) A small segment of RNA synthesized during replication of DNA is ''Okazaki segment''.
