Basically it is more complex then just one locus gene interaction, but basically if both parents have brown hair they can have a child with blonde hair because both parents could be heterozygous for brown and pass on the recessive allele for blonde hair. in simple genetic analysis this would happen to 25% of the children.
Some viruses cause infected cells to <u>lyse. </u> Lysis is the dissolving of the cell by factors like viral, enzymic, or osmosis. Lysis in medical term also means a presence of symptoms of complicated or acute diseases. Example of this disease is the tumor lysis syndrome.
Answer:
Chromatin helps regulate DNA replication.
Explanation:
Chromatin helps condense DNA strands to smaller units that can be easily managed during DNA replication and gene expression. This also prevents the breakage of the strands and facilitates equal distribution of chromosomes during cell division (during mitosis and meiosis).
The respiratory system is the set of organs, which allows breathing, that is to say, the gaseous exchanges between the body and the environment.
The respiratory system can be easily assimilated to a bunch of grapesThe main stem of this branch of grapes is the trachea. then divides into smaller ducts called bronchi. Next, it branches into even smaller branches called bronchioles.
The grapes themselves are the alveolar sacs that are branched with the bronchioles. (each grape is an alveolar sac, the functional unit of the respiratory system).
Proteins that are postsynaptic get neurotransmitters given by the presynaptic proteins.
