Answer:
Helicase
Explanation:
The DNA double helix is unzipped by the enzyme *HELICASE*. The enzyme breaks the hydrogen bond between the bases thereby causing the strands of the double helicase to unzip. The action of the helicase enzyme uses energy from ATP. The unzipping of the double helix does not occur in a swift move. One end of the DNA molecule with 5'-3' is opened up showing the antiparallel single strands. The end that is opened is termed INITIATION SITE of replication. The opening look like someone standing with legs wide open. The wide opening is called REPLICATION FORK. The single strands of the fork are usually unstable but their stability is maintained by the DNA-binding-proteins. Having opened the double helix, the replication would then continue in the 5'-3' direction of one of the two antiparallel single strands.
There could be many answers to this question, but a possible one is embryo!!
Peyer patches are lymphoid nodules located in the walls of the small intestine.
Peyer patches are also known as aggregated lymphoid nodules, they are organized in the form of follicles and are round or oval and their surface is free of the villi and depressions that are present throughout the intestinal wall.
Peyer patches mainly consist of B cells and play an important part in the immune system by monitoring intestinal bacterial populations and controlling the development of pathogenic bacteria in the intestines.
