Which type of membrane-bound organelle would be abundant in a eukaryotic cell that is specialized in the storage of triglycerides? Explain. What is a membrane-enclosed structure that performs a specific function in a cell called? A special organelle in a sperm...
Contains all the 23 chromosomes of the sperm cell, that is, half the genetic information of the future embrion. This is the only part of the sperm cell that enters into the egg cell. As such it is the most important part of the spermatozoon. Its purpose is to fuse with the nucleus of...
Frequently in embryo development cells that are not used to construct the soma—the body of the new individual—are put aside but remain in stock as primordial germ cells. Such cells are known in nematodes, insects, and vertebrates.

EcDNA contain more than one full gene and regulatory regions, lack a centromere and telomere and are visible under light microscope with DAPI staining [51]. EcDNA can be found in 46% of tumor cell lines (17 different tumor types, 2572 dividing cells) [49]. It is present in around half ...
