I think the presence of a signal affect the expression of the structural enzymes in that it stops the production of the structural enzymes. Without the signals, the structural enzymes are produced. Genomic DNA contains both the structural genes that encodes products that serve as cellular structures or enzymes, and regulatory genes, which encode products that regulate the expression. In multicellular organisms allows for cellular differentiation while in single celled organisms like prokaryotes , regulation ensures that a cell's resources are not wasted making proteins that the cell does not need at that time.
Answer:Transcription.
Nucleus is the site of these converti
Explanation:
The DNA of a specific gene is the template f or the complementary base-pairing,
RNA polymerase enzyme is the name of the enzyme that catalyzes thr conversion of the pre- mDNA to fully mature mRNA..
This process involves splicing t;hat is the removal of precise introns from the primary RNA transcripts.
It is controlled by complexes of protein and spliceosomes.
Answer:
The stomach of a cattle and other ruminants include a pouch like structure called a recticulum, where bacteria help breakdown the animals food.
Explanation:
Cattle is a ruminants and ruminants animals are animals that can chew the cord and have four chambered stomachs. Their stomachs are rumen, recticulum, abomasum and omasum. The abomasum is considered the true stomach because it has a structure similar to that of non ruminants. Recticulum is the second chambered stomach that is pouch like and it contains bacteria they help breakdown food. It collect the small digests molecule and move them to omasum.
