Are segments of DNA Code for traits Are a sequence of nucleotides Are located on chromosomes

Non Coding Regions

Is converting the gene into a polypeptide Involves: Reading the code (transcription) Making the protein (translation)
Image of page 5
The protein produced gives you a trait or characteristic E.g. green skin, Enzymes

helps converts genes into polypeptides Is a second type of nucleic acid (DNA was the first) It is made of nucleotides (a base, a sugar and phosphate group)
Image of page 8
There are 3 types of RNA : 1. m(RNA)… Messenger RNA 2. t (RNA)….Transfer RNA 3. r(RNA)…..Ribosomal RNA

Is called messenger RNA Acts as a the bridge between DNA & protein synthesis Transfers information from the nucleus
Image of page 13
It takes the DNA “message” to the ribosome….. The message tells the ribosome which polypeptide it will create
Image of page 14
Image of page 15
Is called transfer RNA Transfers (brings) amino acids from the cytoplasm to a ribosome
Image of page 16
It contains an anticodon The anticodon pairs with a codon on mRNA by complementary base pairing
Image of page 17
Image of page 18
Is called ribosomal RNA It is an important structural component of ribosomes They make up part of the subunits along with ribosomal proteins

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
