Gene Questions and Answers (Q&A)

Blood typing is a particular way to tell what type you have. Blood typing is done so that you can safely donate blood or receive a blood transfusion. To determine our blood type, a sample is necessary. The test to confirm your blood group is called ABO typing. Your blood sample is mixed with antibodies against type A and B blood.

Then, the sample is checked to see if the blood cells stick together. If blood cells hold together, it means the blood reacted with one of the antibodies. The second step is called back typing. The liquid part of your blood without cells is mixed with blood that is known to be type A and type B. Type O blood contains both antibodies. People with ORh blood are universal donors.

Two sequences of DNA that are found in close proximity to each other within a chromosome. They will most likely remain together. Even though genes change during the meiosis process, in this situation with the genes being linked, it is less likely that it will be divided. These genes will most likely be inherited together during the meiosis phase of sexual reproduction.

This seems to contradict Gregor Mendel’s Law of Independent Assortment which describes that genes and the traits inherited by our parents come individually. They do not come together. However, after stating this, there were several exceptions discovered to this rule. For example, if a gene is in close proportion to another gene, these two genes may be linked.

The correct answer to this question is A, DNA to RNA. In the process of gene expression, transcription is the first step. Transcription is the process of copying a DNA sequence to create an RNA molecule. RNA polymerases are what carry out the act of transcription.

It does so by linking nucleotides together to form an RNA strand. There are three stages of transcription. This includes termination, initiation, and elongation. After transcription, the RNA molecules must be processed. This process consists of the splicing of the RNA molecules and putting a 5 cap and poly-A tail on the ends of them.
