The template strand of DNA is 3’ – TAC – 5’. The anticodon that will pair the corresponding mRNA codon will be:
1. 5’ – AUG – 3’
2. 5’ – UAC – 3’
3. 5’ – CAU – 3’
4. 3’ – TAC – 5’

The RNA polymerase holoenzyme transcribes:

1. the promoter, structural gene and the terminator region

2. the promoter and the terminator region

3. the structural gene and the terminator region

4. the structural gene only.

The number of genes in human genome is found to be much less than what was initially expected as humans are capable of making large number of diverse proteins. This paradox can be best explained by:
1. Gene editing
2. Alternative splicing
3. Intron excision
4. Post transcriptional modification

1. 0
2. 1
3. 2
4. 4

A cis acting factor that place very important role in eukaryotic transcription will be:

2. Transcription factors.
3. Enhancers.
4. Shine Dalgarno sequence

3. Proceeds unidirectionally
4. Moves bidirectionally

A mutation at a gene locus changes a character due to change in
1. DNA replication
2. Protein synthesis pattern
