Answer:
The correct answer is - to produce recombinant that leads to genetic variation.
Explanation:
Random shuffling or random alignment of the chromosome during gamete formation allows the formation of new allele combinations. In the crossing over the parts of the homologous chromosomes are switched between homologous and recombinants are formed that shows are genetic variation.
So, now they have different allele combinations and chromosome combinations as well. Random shuffling does not provide genetic variations as crossing over
Dolly was a first mammal cloned from an adult somatic cell, she was a domestic sheep, using the process of nuclear transfer. Dolly showed that genes in the nucleus of such a mature differentiated somatic cell are still capable of reverting to an embryonic totipotent state.
The totipotent cell is a cell that can form all the cell types in the body, it has an ability of a single cell to produce and divide all of the differentiated cells in an organism.
The correct answer is that they produce ATP.
Mitochondria are considered an essential part of the cells as they consume food and produce energy in the process, which is utilized by the rest of the cells.
The prime activity of mitochondria is to generate energy for the cell. The cells utilize a specific molecule for energy known as ATP. The ATP is produced inside the mitochondria, that is, why one can consider mitochondria as the energy house of the cell.
Answer:
no. one or more like atoms in a element
