Key points about codons:

Triplet code: A codon consists of three bases.

Function: Each codon codes for a specific amino acid.

Location: Codons are found on messenger RNA (mRNA).

Explanation

Divergent evolution occurs when two species that share a common ancestor evolve different traits or characteristics over time due to adapting to different environments or ecological niches.

This process leads to increased differences between the species.

Explanation

Capacitation is the physiological process that sperm must undergo to gain the ability to penetrate and fertilize an egg.

This process occurs after the sperm enters the female reproductive tract

They involve a series of biochemical changes that enhance the sperm's motility, and its ability to bind to the egg.

It is distinct from spermiogenesis (the final stage of sperm development), the acrosome reaction (which occurs later during fertilization), and fertilization itself
