The aswer is b. Vascular Cambium
it is a plant tissue which is located between Xylem and Phloem in the stem and root of a vascular plant and the source that produces Secondary xlem and phloem
Nb : Vascular Cambium does not transport waters , minerals, it only produce Xylem and Phloem which add the tree's girth
The first step in protein synthesis is the transcription of mRNA from a DNA gene in the nucleus. At some other prior time, the various other types of RNA have been synthesized using the appropriate DNA. The RNAs migrate from the nucleus into the cytoplasm.
It gets smaller because that's what Lynx eat. If their food population goes down, they can't eat. So the Lynx might die.
The BRCA 1 and BRCA 2 genes are two genes that are sought in the genetic study of an individual in order to seek a predisposition to breast cancer (in women and also in men).
The genes of Tay-sachs, are researched in order to diagnose or eliminate Tay-sachs disease.
The first difference lies in the goal of the research: for the BRCA (screening) genes, a predisposition is sought and for the Tay-sachs genes, it is sought to confirm the disease.
The second lies in the technique used:
The first step in the study of these genes is to isolate and replicate them. The best technique for this is the PCR (polymerase chain reaction). By using primers we can amplify the gene we want. So the primers used in BRCA and Tay-Sachs research are necessarily different.
