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

Degeneration of genetic code is due to
1. First member of codons
2. Second member of codons
3. Third member of codons
4. Entire codons.

In gene mutation, adenine is replaced by guanine. It is
1. Frame-shift mutation
2. Transcription
3. Transition
4. Transversion

In bacterial DNA replication, synthesis starting from the site of origin of replication
1. Involves RNA primers
2. Requires telomerase
3. Proceeds unidirectionally
4. Moves bidirectionally

On which organism Beadle and Tatum worked to propose one gene-one enzyme hypothesis
1. Drosophila
2. Escherichia coli
3. Neurospora crassa
4. Nostoc

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
