starts with promoter region and ends in terminator region

starts with palindrome regions and ends with rho factor

What was the key finding from Griffith's experiments using live and heat-killed pathogenic bacteria?

Genetic material can be transferred from dead to live bacteria

Bacteria with a smooth coat could kill mice

Bacteria with a rough coat are not lethal

Elongation of the RNA polynucleotide chain always takes place:

5 ' - 3 ' direction with new nucleotide always added at the 3 ' site

In any direction along the entire length of single DNA strand

There are two strands which run antiparallel one in 5 ' → 3 ' direction and other in 3 ' → 5 ' direction

The proportion of adenine in relation to thymine varies with the organism

The total amount of purine nucleotides and pyrimidine nucleotides is not always equal

There are two strands which run parallel in the 5 ' → 3 ' direction

Which one of the following is wrongly matched?

Transcription - Writing information from DNA to tRNA

Translation - Using information in mRNA to make protein

Repressor protein - Binds to operator to stop enzyme synthesis

Operon - Structural genes, operator and regulator
