Explanation: In eukaryotes, ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs (mRNAs). An mRNA travels to the ribosome, which uses the information it contains to build a protein with a specific amino acid sequence.
Fraternal twins are not genetically identical because one chromosome from each pair randomly passes during meiosis and leads to differences between the siblings. Meiosis involves independent segregation of sex chromosomes.
Meiosis is a type of reductional cell division by which a parent cell produces four daughter (gametes) cells having half the genetic material.
Fraternal twins occur when two egg cells are released by the mother, which are fertilized by a different sperm.
During meiosis, sex chromosomes are separated and segregate in a random manner in daughter (sex) cells.
