What role do the following cellular components play in the storage, expression, or transmission of genetic information. Drag the terms on the left to the appropriate blanks on the right to complete the sentences.
a. nucleolus
b. centromere
c. ribosome
d. chromatin
e. centriole
f. mitochondrion
1. contains the genetic material that is responsible for maintaining hereditary information.
2. is the structure for the production of ribosomes.
3. is the site of oxidative phosphorylation and production of relatively large amounts of ATP.
4. is the structure where various RNAs, enzymes, and other molecular species assemble the primary sequence of a protein.
5. is a cytoplasmic structure involved (through the formation of spindle fibers) in the migration of chromosomes during mitosis and meiosis of animal cells.
6. serves as an attachment point for sister chromatids and a region where spindle fibers attach to chromosomes.

a. Nucleolus: The nucleolus refers to a composition, which develops with the assistance of the nucleolar organizer region present in the eukaryotes. It constitutes protein and ribosomal DNA and is a location where the generation of ribosomes takes place.  

b. Centromere: The prime function of the centromere is to function as the point of attachment for sister chromatids and is a place where the attachment of chromosomes and spindle fibers takes place. The differentiation of centromere takes place at the time of mitosis and meiosis II, which helps in the distribution of chromosomal substances to the daughter cells.  

c. Ribosome: The ribosome refers to the composition where different forms of RNAs, enzymes and other components help in the alignment of the primary sequence of a specific protein.  

d. Chromatin: Chromatin constitutes the genetic information, which helps in sustaining hereditary information and generation of a phenotype.  

e. Centriole: The centriole refers to a cytoplasmic composition, which via the help of spindle fibers assists in the migration of chromosomes at the time of meiosis and mitosis, mainly in the animal cells.  

f. Mitochondria: The mitochondrion refers to a membrane-bound composition situated in the eukaryotic cytoplasm. It is the place where the production of huge amounts of ATP takes place via the process of oxidative phosphorylation.  

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects
