Answer:
Hepatic portal vein , is responsible for the transport of blood from the intestine to the liver.
Explanation:
The Hepatic portal vein also called the portal vein ,
The blood vessel carries blood from the gastrointestinal tract , pancreas , gallbladder and spleen to the liver .
The blood in the blood vessel contains toxins and nutrients absorbed from the digested contents.
Around one third of the total blood of liver flows via Hepatic Portal Vein.
Hence,
Blood is transported from the intestine to the liver in a large vessel known as the <u> Hepatic Portal Vein.</u>
Answer:
4) The mRNA was shorter because of Intron splicing
Explanation:
In eukaryotic cells, the process of gene transcription uses a fragment of DNA as template in order to synthesize a complementary single-stranded RNA molecule known as primary messenger RNA transcript or 'pre-mRNA', which is then processed to yield a mature messenger RNA (mRNA). This mature mRNA is finally used as template to synthesize a polypeptide chain (i.e., a protein) by the process of translation. RNA splicing refers to the processing mechanism by which a pre-mRNA is transformed into a mature mRNA. During RNA splicing, non-coding regions of the pre-mRNA called 'introns' are removed, whereas the remaining coding regions called 'exons' are joined toghether to form a mature mRNA. In consequence, RNA splicing generates an mRNA that is shorter than the originally transcribed gene sequence.
