A repressor controls the lactose operon.

Answer 1

72. Binary fission is not an example of genetic recombination. It is asexual mode of reproduction in bacteria.

73. DNA replication involves polymerase activity. DNA polymerase is the enzyme needed for DNA replication.

74. Translation involves the transfer of amino acids to an elongating chain.

75. Replication requires DNA ligase. DNA ligase joines the DNA fragments that are synthesized on lagging strand.

76. Transcription needs RNA polymerase which is defined as DNA dependent RNA polymerase.

77. Translation involves chaperones for proper folding of proteins.

78. Translation begins with a start codon.

79. Transcription requires a promoter for binding of RNA polymerase.

80. Replication produces okazaki fragments synthesized on lagging strand.

81. Replication needs DNA polymerase which is known as DNA dependent DNA polymerase.

82. True. Formation of RNA from DNA template is known as transcription.

83. True.

84. True. Repressor in lac operon is lactose. Binding of lactose controls the gene expression.
