Answer:
A blood test is used to determine whether the A and/or B characteristics are present in a blood sample. It is not possible to determine the exact genotype from a blood test result of either type A or type B. If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies
Explanation:
DNA is found in the nucleus of a cell. Depending on the type of cell, different parts of the DNA are used (example; if it's an eye cell, the DNA will use the segment that is dedicated to the functions of the eye). When a protein is needed, the DNA will split and in a process called transcription, the DNA messages are copied onto mRNA. The mRNA then leaves the nucleus through nuclear pores, and then travels through the cytoplasm to locate ribosomes which will produce the proteins needed to express whatever trait it codes for.
Answer:
Explanation: Without gene duplication, mutation of genes would not exist. This would prevent organisms from adapting to their environment, making survival much more difficult if not impossible.
