Answer:
21 chromosomes
Explanation:
Meiosis is a type of cell division that produces 4 haploid daughter cells (i.e., gametes) from a single diploid cell. This parental cell undergo one (1) cycle of DNA replication and two (2) cell divisions, thereby, in the case of the Norway rats that have 42 chromosomes, the final number will be 21 (21 x 2= 42)
no, it can definitely get in the cloud
PMAT (Prophase,Metaphase,Anaphase, Telophase)
Answer:
A gene mutation refers to a permanent change in the sequence of DNA, which forms a gene, that is, the sequence varies from what is witnessed in the majority of the individuals. The mutations vary in size, they can influence anywhere from a base pair to a huge section of a chromosome, which comprises multiple genes.
The mutations result in extreme modifications in a species if they modify the manner in which a protein functions. However, a mutation, which directs the formation of altered proteins or the unexpected amounts of proteins is the most general way by which a mutation contributes to disease.
