Something that will hopefully help me..

Transcription

the process that converts DNA into mRNA (single strand) by copying the code and removing the unneeded portions for a specific protein.

Introns and Exons

During transcription, introns are removed while exons are linked to other exons to form mRNA from RNA.

Spliceosome

The molecule that removes the introns and link the exons together to convert RNA into mRNA.

What does mRNA do after it’s been created?

leaves the nucleus and enters the cytoplasm to be translated into a protein. It serves as a template for protein synthesis.

Step 1

find the complements to the DNA sequence and then turn the DNA sequence into the RNA sequence. (ATACGA—>UAUGCU)

Step 2

mRNA has the information written in a language a ribosome can't read.

Translation

Is the process of converting the message into amino acids using CODONS.

3 base code that codes for one AA.

Several codons form a sentence that forms a polypeptide. (protein)

Codons

A three base sequence that codes for one Amino Acid.

How does this occur in a cell?

1. mRNA attaches to a ribosome 2. A tRNA carries complement bases & amino acids to mRNA... linked amino acids form proteins! (RNA reads AA and helps put them in order) - Anti-codon→ complement base "codon" that matches to mRNA strand
