Replication

Replication is the process of copying DNA to produce two identical DNA molecules. It occurs before cell division and is essential for passing genetic information to daughter cells.

 P. 243-245

Differences in Cell Division

The main differences between mitosis and meiosis lie in the number of divisions, the number of daughter cells produced, and the genetic content of the daughter cells (haploid or diploid).

Transcription

Translation

name of process:

gene

Transcription

Transcription is the process of synthesizing RNA from a DNA template. It takes place in the nucleus and is a crucial step in gene expression.

 P. 243-245

Translation

Translation is the process of converting the genetic code carried by mRNA into a sequence of amino acids, leading to the synthesis of proteins in the ribosomes.

 P. 243-245
