13. In a eukaryote, the MRNA that will be translated is much shorter than the primary transcript. What is the best explanation for the difference in length? A. The MRNA to be translated was missing the UTR. B. Exons were not added into the primary transcript. C. Introns have not been spliced from the primary transcript. D. The 5' cap has not been removed from the primary transcript.
Please help me, this is from practice, double check your answers, previous tutors got it wrong
Genetic material is nothing but the sequence of nucleic acids which is called as DNA. It contains all the necessary information required for the proper function and replication of the organism. It is passed from one generation to another generation.
Central dogma of molecular biology:
It states that the DNA which contains the genes are transcribed into messenger RNA and that messenger RNA translates into proteins. It the entire process how proteins are produced from the DNA
DNA coding strand has a coding sequence on which the enzyme RNA polymerase acts and produces m RNA by a process called transcription
the full DNA sequence transcribed into m-RNA the complete sequence is called primary script.
This messenger RNA now moves out of the nucleus by undergoing the post transcriptional modifications
during post translation modifications introns are removed and by splicing mechanisms and final m-RNA is shrinked and then enters ribosomes where it is translated inside with ribsome with the help of t-RNA which contains aminoacids.
