Adding an extra nucleotide to a dna sequence produces what type of mutation

Insertion

Explanation:

A mutation is any alteration to the nucleotide sequence of a DNA. It can result during its replication or be induced by mutation-causing components called Mutagens. When mutation involves a single nucleotide, it is referred to as POINT MUTATION.

Point mutation can occur either when a single nucleotide of a DNA molecule is removed/deleted, when it is replaced/substituted by another nucleotide, or when an additional nucleotide is included to the original sequence.

The last scenario of point mutation above is called INSERTION, the addition of a nucleotide disrupts the manner in which the sequence is read and can subsequently lead to the production of another polypeptide.

explanation:

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
