How does the mRNA used in protein synthesis differ from the original RNA transcript?

What is the apparent function of each of the alterations or modifications?How does the mRNA used in protein synthesis differ from the original RNA transcript?
The mRNA that is exported from the nucleus following transcription differs from the original RNA transcript in two ways ...





(1) The original RNA transcript contains both coding (exons) and noncoding (introns) regions. Surprisingly, most of our DNA is composed of noncoding, ';junk'; DNA. The cell does not want to translate this into protein, so spliceosomes cleave the introns out and DNA ligases glue the exons back together.





(2) To protect the mRNA and prevent it from being degraded by proteases in the cytosol, the nucleus attaches two things to the mRNA: a 5'G-cap, which is basically just a series of guanine nucleotides, and a poly-A tail, a series of adenine nucleotides.How does the mRNA used in protein synthesis differ from the original RNA transcript?
In eukaryotes the gene may be comprised of introns and exons. The introns will be removed and the exons joined, via a process called splicing, to form the mature-mRNA from the pre-mRNA.
The mRNA is translated from the RNA transcript--all Cs will turn into Gs and all As will be Us and vice versa. Also keep in mind the 5'-3' polarity.

  • Taking college courses during high school- how to get those credits on your transcript?

    I'm taking college courses and community college in addition to my standard 6 periods at high school. I still have not gotten credit for one of the classes I took in the summer, and I am wondering how to get it on to my transcript. It is very important, because without this credit I cannot graduate, even though I took the course. Thanks in advance!Taking college courses during high school- how to get those credits on your transcript?
    Yea, my school has 6 periods too, so we are limited of taking College courses or APs in my school.. But it will appear on ur trancsript and ur average will be slightly higher if u calculate the numbers on the transcript cause the grades are weightedTaking college courses during high school- how to get those credits on your transcript?
    You need to talk to your guidance right away because this is important. Some high schools do not accept college credits as high school graduation requirements. Since I do not your school, I cannot tell whether your school does accept those credits. However, those credits will still be there when you go to college, where you have to transfer those credits to the college you are attending. So you need to see your guidance counselor.
    You need to ask the college for a transcript to be sent to your high school. I think your prerequisites are ok, since you wouldn't be able to take the class without them.





    Just walk on over to the office and ask them for an offical transcript to be sent to your school!
    were they prerequisite classes to something you need to take. Sometimes the colleges will make you take a course that you need in order to take another course bc you didn't score high enough on the placement test.
    Just go to the front office at your high school and tell them about it. They will work with the academic office of the community college to get things straightened out.

    How can I get into college even if I don't have a transcript of records of my high school grades?

    I want to enter college but my high school transcripts got lost due to some unavoidable circumstances. I tried to get other copies but even my high school lost their records due to a natural calamity. How do I do this? I'm sort of worried that this could be a hindrance in my enrollment. Any tips out there? Are there exams I could take or what? Thanks!How can I get into college even if I don't have a transcript of records of my high school grades?
    Let us know, please, what state you live in. Some states have different procedures, but your transcripts will be on record with some office within your state's government. There might be a state Commission on Education, as in New Jersey, or there might be a State Board of Education, as in many states. You can check your state's Web site for info or even contact your state legislative representative.





    Schools are required by law to keep duplicate records in a safe, off-premise location. The records exist, and finding them should not be too big a challenge. A few letters and/or phone calls or even an in-person visit (if convenient for you) should get the job done. Be aware that there might be a moderate fee.





    Even without the transcripts, most colleges will accept you if you can document your successful attendance in some other way, but the transcripts will be valuable. Sometimes even employers request them.





    You can do it, and if you need additional information, please do let us know what state you live in.

    Can I have old failing grades from a community college expunged from my transcript?

    I failed 5 classes at a community college over 10 years ago because I just stopped going and didn't care about college at the time. I now am back in school at a different community college, getting A's and B's but my old F's are killing my overall GPA. I want to just erase those classes because I don't need them. Is there a way to petition to the old college to have them expunged?Can I have old failing grades from a community college expunged from my transcript?
    You have to know the answer before you asked it. No. l had the same problem, Here l am in school after about six or so years after high school my first year was not that good then l started getting A's. In the end all l needed was any one grade pushed up one half a grade and l would of been on the deans list. In the end l never made the dean's list. Got an idea you can retake those courses then they would have to post you better grades. Good luck.Can I have old failing grades from a community college expunged from my transcript?
    i have the same problem, my old grades pulling my GPA down! i don't think it is possible! but if you find out let me know too!! i need to knoww!!


    wait but i think u can ask ur advisor at school can't you?

    When applying for high profile jobs do they generally ask for your college transcript?

    Or just go by your resume and application. Do they usually ask your GPA? I am an accounting major.When applying for high profile jobs do they generally ask for your college transcript?
    I'd say about 75% of the jobs I applied for asked for an unofficial copy of my transcript. I would assume they are looking for trends in your grades, where your strong points/weaknesses are, something else to judge besides a GPA.





    My early years I kinda slacked off, and improved my gpa over time, which showed in my transcript. I explained that I wasn't focused my freshman year, and was adjusting(which was true). I think it's much better to start off with a low GPA and work your way up then to start with A's and B's and go down to C's.When applying for high profile jobs do they generally ask for your college transcript?
    I've never had an employer ask for transcripts, but it wouldn't be a bad idea to have them handy, just in case. If they're concerned about making sure you haven't lied on your resume or application, odds are they'll do a background check.

    Can I just not send a transcript to a college I transfer to?

    I just transfered to a new college this year ansd ended up missing way to many classes while visiting my mother who is sick with cancer. I do not like the school that much and thought about transferring somewhere else. If I did that, would I be able to send my transcript from my first school and just neglect the transcript from this school? Would a school frown upon that if they found it, or is it ok to do?Can I just not send a transcript to a college I transfer to?
    I did the same thing but where they can find out is through financial aid. If you are not getting federal aid then don't worry about turning in the other transcript. If you are - it may be more difficult but worth a shot.Can I just not send a transcript to a college I transfer to?
    As a general rule you cannot pick and choose which transcripts you want to send and which ones you don't want to send. You might want to find a university that has something called an ';academic fresh start program'; or something similar. I don't really know of anything stopping you from self selecting transcripts but I would think it might be frowned upon by many institutions.
    no you have to send a transcript or they will not know what clases you already passed or how many credits you have....with out them whats to stop a person from saying they need 3 credit to graduate
    ask your guidance counselor
