What is to make store and transmit genetic information?
Long chains that make up DNA (it’s building block)
What is a nucleotide?
The 3 components of DNA
What is deoxyribose sugar, phosphate group and nitrogen base?
NAMES and COMPLEMENTS of the nitrogenous bases of DNA
What Adenine and Thymine; Cytosine and Guanine?
Scientists credited with the structure of DNA
Who are Watson and Crick?
Full name of RNA
What is Ribonucleic Acid?
3 ways RNA is different than DNA
What is Type of sugar, uracil, single stranded, Location, multiple forms?
Functions of 3 types of RNA
What is mRNA: messenger, tRNA, carries amino acids, rRNA, location of protein synthesis?
RNA molecule complementary to adenine
What is uracil?
Name of the components labeled on the RNA molecule #1 #2
What is amino acid for #1 and anticodon for #2?
Location of transcription and translation
What is the nucleus (transcription) and ribosome (translation)?
Identify the mRNA strand transcribed from this DNA AAA-TAC-GCG-TGA
What is UUU-AUG-CGC-ACU?
What enzyme is responsible for catalyzing transcription (adding the bases)
What is RNA polymerase?
What a codon codes for
What is an amino acid or stop signal?
What anticodons do during translation
What is make sure the correct amino acid is delivered to the ribosome?
The reason cells must control gene expression
What is so their genes will only be expressed when needed?
What is a group of genes that code for functionally related proteins?
What inducer molecules do that allows for transcription
What is changes the shape of the repressor molecules?
What causes the lac operon to be shut off
What is lactose being absent?
How the inducer molecule works
What is it removes the repressor molecule from the operator?
Term used to describe the nucleotide triplet that specifies a particular amino acid
What is a codon?
Term used to describe a substance known to cause cancer
What is a carcinogen?
Name of the 2 types of nitrogen bases
What are purines and pyrimidines?
Enzyme responsible for unwinding the DNA strand so it can replicate
What is helicase?
Describe the steps of DNA replication
What is : 1.Helicase breaks H bonds between bases (unwinds) this is called the replication fork 2.DNA polymerase creates the new strand by adding a complementary bases until it reaches a stop signal?
