Photosynthesis occurs in the leaf (source), making sugars: fructose and glucose. These are converted to sucrose and are actively transported into the phloem (sieve tube element) by companion cells. The incre...

Proteins are polymers of Aminoacids. Aminoacids are joined in condensation reactions (water is eliminated) by peptide bonds. The primary structure is the order of aminoacids in the protein, while the seconda...

The DNA replication is a process in which double stranded DNA molecule is divided into two daughter copies during cell division (mitosis). The replication of DNA takes in stages by semi conservative method i...

DNA replication was thought to be either conservative (two old strands of DNA stay together), semi-conservative (one old and one new strand of DNA), or dispersive (bit of old and newly replicated DNA in each...

-A genetic mutation within the lactase gene, for example base substitution, changes a codon -This codon codes for a different amino acid to be transcribed and translated-Therefore the sequence of amino acids...
