Explanation:
Los conductos o vasos linfáticos son tubos que transporta tanto al líquido linfático (linfa) como glóbulos blancos que fluyen a través del sistema linfático. Estos conductos se inician en el intersticio y terminan en conductos de mayor tamaño que desembocan en la base del cuello, entre las venas yugular interna y la subclavia. A medida que va entrando en los tejidos, los conductos linfáticos se van haciendo cada vez más angostos y finos, convirtiéndose finalmente en capilares linfáticos, donde las sustancias que no pueden penetrar los vasos sanguíneos son recogidas por estos capilares.
Answer:
B
Explanation:
CRISPR-Cas9 is a gene-editing mechanism that is harnessed from bacteria’s immune system used to cut apart foreign genetic material such as that of bacteriophages. CRISPR-Ca9 has a guide sequence that is used to identify the target sequence. The Cas9 enzyme cuts this target DNA and is replaced with the required piece.
In cancer treatment, the mutated DNA can be replaced, this way, with the wild type.
The mutations may be a
substitution, deletion, inversion, or addition.
The mutations in insulin may alter its active sites responsible
for receptor binding, or the time taken for the insulin
to be degraded (half-life). Mutation on insulin may cause diseases such as hyperproinsulinemia
or hyperinsulinemia.
The nitrogenous bases (guanine,cytosine,thymine,adenine) code for our traits.
