Answer:
Two rounds
Explanation:
Meiosis is characterized by one round of DNA replication followed by two rounds of cell division, resulting in haploid germ cells. Crossing-over of DNA results in genetic exchange of genes between maternal and paternal DNA.
Mitosis is the process of cell division, where one parent cell divides to produce two genetically identical daughter cells. This process is vital in growth and tissue repair.
The reason that tissue from the fetal stage is helpful in studying mitosis is because mitosis is continuously and rapidly occurring in this phase of life in humans. The high rate of mitosis is due to the need for the fetus to grow rapidly and develop the necessary parts for it to be born.
Splicing, adding of the cap and tail, and the exit of the mRNA from the nucleus.
<h2>Answer:</h2>
The correct sequence of organelles involved in making and packaging of proteins is option C: ribosomes, endoplasmic reticulum, and Golgi complex.
<h3>Explanation:</h3>
- The protein synthesis which is the translation of mRNA is done on <u>ribosomes.</u>
- As the protein is produced then it goes for modification in the <u>endoplasmic reticulum.</u>
- After some modifications proteins are packed into vesicles for the intercellular and intracellular transport.
- This packing is done in <u>Golgi apparatus.</u>
