Explanation:
The 5' cap is a specially altered nucleotide (7-methylguanosine) attached via a 5'-5' triphosphate linkage to the 5' end of a eukaryotic mRNA molecule shortly after transcription begins. Its primary functions are to protect the nascent mRNA from degradation by 5' exonucleases, to facilitate the export of the mature mRNA from the nucleus to the cytoplasm, and, crucially, to be recognized by the eukaryotic initiation factor 4E (eIF4E), which is essential for recruiting the ribosome to the mRNA to initiate translation.

Explanation:
The Law of Segregation (Mendel's First Law) states that an organism possesses two alleles for each trait, and these alleles separate (segregate) during the formation of gametes (meiosis). Each gamete receives only one allele. This explains why a recessive trait can disappear in the F1 generation but reappear in the F2 generation.
