DNA Structure
The organelle where transcription occurs.
What is the nucleus?
Where the mRNA goes after it is processed?
What is ribosome?
If the DNA sequence is GCAATC, this is the mRNA sequence.
What is CGUUAG?
The purpose of replication.
What is to produce 2 identical strands of DNA?
The molecule produced in transcription.
What is mRNA?
The part of pre-mRNA that is spliced out
What are introns?
The type of bond found in the sugar - phosphate backbone of DNA
What is covalent bond?
What is phosphate and sugar (deoxyribose)?
The enzyme that opens the strand of DNA.
What is helicase?
The enzyme involved in transcription
What is RNA Polymerase?
The structure added to the front and of an mRNA molecule before it leaves the nucleus
What is a 5'cap or methyl cap?
The strand of DNA that is produced in the direction of the replication fork and is continuous
What is the leading strand?
This is the name of the building blocks of DNA (it contains three molecules).
What is nucleotide?
the enzyme that adds base pairs to the template strand during repilcation.
DNA Polymerase
The region where the transcription initiation complex is formed>
What is promoter (TATA Box)?
The structure added to the end of the mRNA to prevent breakdown in the cytoplasm
What is poly-A tail?
The type of bond that forms between nitrogenous bases of DNA
What are hydrogen bonds?
The 3 parts of a nucleotide.
What is phosphate, sugar, base.
The enzyme that fills gaps in genetic information formed by Okazaki fragments.
DNA Ligase
The start codon
What is AUG?
The structure through which the mRNA can leave the nucleus
What is a nuclear pore?
The process that allows for one gene to code for more than one protein
What is alternative splicing?
