The process of constructing an mRNA molecule from DNA is know a transcription. The bases pairing rules ensure that the DNA code is conserved in the sequence in the mRNA
Answer:
Because offspring with two parents will share half of each parent's DNA.
Explanation:
Sex cells contain half of the genetic information of an organism's regular cells. This is because a sexually-produced organism will be unique; it will share genetic information with both of its parents, rather than be identical to its bearer (like an asexual organism would be). When a sex cell meets another sex cell, their DNA will meet as well and change/adapt to suit the organism. If a sex cell had all the information needed to create an embyro, instead of half, which requires another cell's information to fill the DNA void.... well, it would just do it.
The main portion of the cell is called the soma or cell body. It contains the nucleus, which in turn contains the genetic material in the form of chromosomes. Neurons have a large number of extensions called dendrites.
Well a person with HIV would only have AIDS if he/she has really low number of CD4 cells if this is the case that is when doctors would diagnose that person with AIDS. Hope I helped
