If a person forgets to take the reading of his cell culture data now he needs to conclude among the two plates A( with 16 cells) and B (with 128 cells).

If these plates A and B happen to be of human cells, then during 135th hr of the culture the cell will be undergoing which number of division?

1. 45th division

2. 31st division

3. 120th division

4. 64th division

The inter phase in human cell cycle lasts for

1.      24 hrs

2.      95% part of cell cycle

3.      More than 95% of the duration of cell cycle.

4.     Around 90% of the duration of cell cycle

During G1 phase

1.      Cell is metabolically active

2.      Replication of DNA

3.      Translation and Transcription occurs

4.     Both 1 and 3

During S phase

1.      The DNA per cell doubles

2.      The protein per cell becomes half

3.      The chromosomes also get double

4.     The content of a diploid cell increases from C to 2C

To make 350 cells, how many times the DNA duplication will occur?

1.      350

2.      349

3.      175

4.     174

During 35th hr of cell division, which number of division must be going on in an yeast culture of 128 cells

1.      Cell culture has not reached to that limit

2.      127th division

3.      34th division

4.     105th division

Number of chromosomes in onion root tip cell at G1 phase will be

1.      16

2.      12

3.      8

4.     6

The number of chromosomes in onion root tip cells at G2 phase will be

1.      16

2.      12

3.      8

4.     6

Number of chromosomes at S phase in onion cell will be

1.      16

2.      12

3.      18

4.     8

What will be the amount of DNA content before the S phase

1.      C

2.      2C

3.      3C

4.     Can be any amount
