Answer:
Through a circumstance known as "secondary transfer DNA", or "Touch DNA".
Explanation:
Most times when a crime is committed, DNA samples are obtained from surfaces in the scene where the crime was committed. There is a very huge possibility of picking up the DNA of someone who was never at the scene of the crime and this is a result of a condition known as Touch DNA.
Because we touch several objects which can be moved to different locations and touch people who are also always mobile, our DNA cells can find their ways to a crime scene where we had never physically been to. This can lead to false verdicts of guilt.

Answer:
Some proteins on the surface of a mammalian cell contain carbohydrates. These proteins are synthesized by endoplasmic reticulum _______ and the sugars are added in ___ ER/Golgi__ apparatus.
Explanation:
The protein part of all glycoproteins are synthesized from polyribosomes that then bind to the endoplasmic reticulum (ER). Then the processing of the sugar groups occurs co-and post-translational in the light thereof continuing in the Golgi apparatus for the N-linked glycoproteins.
There are some proteins that are glycosylated inside the ER and then pass to the Golgi (N glycosylation) and others in the Golgi directly (in case of O-glycosylation)
Answer:
The correct answer is - sporophyte and gametophyte.
Explanation:
In seed producing plants such as gymnosperm and angiosperms the sporphytic part of life cycle is more dominant than the gametophytic part of life cycle. Sporophyte life cycle arise just after the formation of the zygote formation from fertilization of the gametes. The seeds are sporophytic structure that are dispersed to grow and be a full sporophytic plant with root, stem and leaves.
In mosses and ferns the case is different as there are no seed forming present the spores that are gametophytic as has n number of chromosome disperse to produce gametophytic plants that are comparatively small to sporophytic ones.
Thus, the correct answer is - sporophyte and gametophyte.
