Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as true-breeding. In this process the parents will pass down specific phenotypic trait of their offspring. True bred organisms will have pure genotype (genetic make up of an organism) and will therefore produce certain phenotype.
Virus infection domain cell
The answer is c!
Explanation:
In conjugation, DNA is transferred from one bacterium to another. After the donor cell pulls itself close to the recipient using a structure called a pilus, DNA is transferred between cells.
The right option is; slab-pull
The main source of downward convection flow in the mantle is called slab pull.
Slab-pull is the force applied by a cold, dense oceanic plate descending into the mantle as a result of its own weight. This process is known as subduction. The oceanic plate has a density higher than that of the hotter mantle below it and the difference in their density causes the plate to submerge into the mantle.
Answer: Junk DNA.
It does not code for protein and for a long time scientists thought it was useless. Hence the Junk DNA name.
