Answer:
Frameshift mutation is caused by the addition or deletion of a base pair in the DNA of a gene.
Explanation:
Frameshift mutation also known as a framing error or a reading frame shift.
Frameshift mutations are due to either insertions or deletions of nucleotides. This causes the entire DNA strand to elongate or to shrink in size.
There are two types of frameshift mutations.They are insertions and deletions. Insertions involve the insertion of one of more extra nucleotides into a DNA chain.
Several diseases have frameshift mutations like HIV, Crohn's disease, cystic fibrosis etc.
Yes that is true. The gray matter of the cerebrum is the area of the brain where nerve cell bodies make connections, called synapses, that control brain activity.
White matter, on the other hand, is mostly the axons of neurons. The pale fatty insulator of axons, myelin, is mainly responsible for their whitish appearance on gross examination.
