Answer:
A) They only replicate the same time as the larger chromosome.
Explanation:
- Plasmids are small, circular, double stranded DNA molecule, which can replicate independently from its chromosomal DNA.
- If plasmids are used for experiments, they are called vectors.
- Scientists use plasmids as tools for cloning, transferring and manipulating genes.
- They are distinct from chromosomes in being non-essential.
- Plasmids are sometimes present in archaea and eukaryotic organisms.
- Plasmids often carry genes that benefit the survival of the organism, such as by providing antibiotic resistance.
- They do not replicate the same time as the larger chromosome.

Answer: the answer is 3red: 1pink flowers .
Explanation: A petal colour R is dominant to pink flower r =Rr .while crossing it with a heterozygous red flowered plant =Rr.
Ie: R r
R RR Rr
r Rr rr
The ratio of the flower colour is 3 red flowers and 1 pink
Answer:
The correct answer will be option-A
Explanation:
Colchicine is the drug that prevents the assembly of the mitotic spindles which halts or stops the cell cycle.
The colchicine acts by inhibiting the microtubule polymerization thus mitotic spindles which takes place after the condensation of the chromosomes during prophase and pre-metaphase.
This acts as checkpoint which can halt the cell cycle at the phase of chromosome condensation.
Thus, option-A is the correct answer.
