Which of the following statements regarding DNA are true-DNA replicates itself-Hydrogen bonds hold the two strands of DNA together-DNA replication results in errors only once in every billion bases replicated-DNA is usually single-stranded-DNA has a repeating five-base structure.
Because double stranded structure always belong to DNA -helix structure belongs to the secondary structure of proteins. Excision may be imprecise D. 1Which of the following is not true about DNA.
It contains nucleotides that are composed of three parts namely sugar molecule nitrogenous bases and a phosphate molecule. These viruses are enveloped and have a genetic blueprint in the form of two single stranded Ribonucleic acids. 1 Identify the correct statement regarding the function of ribonucleic acid RNA a messenger RNA serves as a template for synthesis of proteins.
Which of the following statements correctly describes the timing of DNA synthesis. A DNA lacks a free hydroxyl group on the 2-carbon atom of its sugar. DNA wraps around an octamer of histones to form a bead-like structure called a solenoid B.
It must occur before a cell can divide. 12 Which of the following statements regarding DNA is TRUE. E DNA contains thymines which make it more chemically stable.
Two complementary strands are duplicated. The eukaryotic nuclear pore interacts with importins to allow mRNA to reach the cytoplasm. Repressor protein prevents entry to the lytic cycle and confers immunity to superinfection E.
Identify the true statements regarding DNA. DNA is synthesized only during mitosis. Integration within the host chromosome is random not site-specific C.
