During transcription, holoenzyme RNA polymerase binds to DNA sequence and DNA assumes a saddle like
structure at that point. The sequence is called
1. AAAT box
2. TATA box
3. GGTT box
4. CAAT box.

Okazaki fragments during DNA replication
1. Polymerise in 3’ → 5’ direction and form replication fork
2. Prove semiconservative DNA replication
3. Polymerise in 5’ → 3’ direction and explain 3’ → 5’ DNA replication
4. Cause transcription

A sequential expression of a set of human genes occurs when a steroid molecule binds to
1. mRNA
2. DNA sequence
3. tRNA
4. Ribosome

What is not for genetic code
1. It is unambiguous
2. A codon in mRNA is read in a non-contiguous fashion
3. It is nearly universal
4. It is degenerate

Removal of RNA polymerase III from nucleoplasm will affect the synthesis of:
1. t-RNA
2. hn-RNA
3. m-RNA
4. r-RNA

Given below is the diagrammatic representation of one of the categories of small molecular weight organic compounds in the living tissues. Identify the category shown and the one blank component "X" in it. 

Category                  Component
1. Cholesterol             Guanin
2. Amino acid               NH₂
3. Nucleotide              Adenine
4. Nucleoside               Uracil

DNA- dependent RNA polymerase catalyzes transcription on the strand of the DNA which is called the     
1. Antistrand
2. Template strand
3. Coding strand
4. Alpha strand

DNA fragments are:
1. Positively charged
2. Negatively charged
3. Neutral
4. Either positively or negatively charged depending on their size

Production of human protein in bacterial genetic engineering is possible because           
1. Human chromosome replicate bacterial cell
2. Mechanism of gene regulation is identical in humans and bacteria
3. Bacterial cell can undertake RNA splicing
4. Genetic code is universal

Which human chromosome has maximum and minimum genes located on it respectively?

1. X and 1
2. X and Y
3. Y and 1
4. 1 and Y
