Explanation:
leukocyte cells as neutrophils has the property of phagocytosis. and lymphocytes cells such as B & T lymphocytes in which b-lymphocytes produces antibodies against particular antigen and T Lymphocytes destroy infected cells.
Answer:
c. Crossing over
Explanation:
In meiosis, crossing over refers to the process where<u> homologous chromosomes 'combine' with each other in order to exchange genetic material</u>, which results in genetic variation. This process takes place during Prophase I of the <u>first meiotic division</u>.
Crossing over is extremely important for the variation - and survival - of a species, as it results in numerous genetic combinations that are passed from generation to generation.
Answer:
codominance
Explanation: a person must have a mutation in both copies of the CFTR gene to have CF, so I WOULD SAY codominance but double check
Answer:
The consequence of this error will be the waste of material, since several nucleotides were placed in the reaction and will not be used.
Explanation:
There are several DNA sequencing protocols and although we don't know which one the GeneTech, Inc. employee is using, we can say that the fluorescence-labeled di-deoxyribonucleoside triphosphates will be used to make countless copies of the DNA particle that he wants to sequence.
As we know, DNA replication separates the DNA strands and uses each strand to make copies of new DNA molecules. These copies are made with the DNA polymerase enzyme by adding deoxyribonucleosides to the new tapes. As the enzyme is highly regulated and has a DNA strand as a template for the new strands, it will not add nucleotides beyond what is necessary.
Therefore, by placing excess di-deoxyribonucleoside triphosphates in the reaction, the consequence will be just the waste of product.
