DNA Structure
The components of a nucleotide
What are a deoxyribose sugar, phosphate group and one of the following nitrogen bases: adenine, cytosine, guanine and thymine?
Pairs with thymine.
What is adenine?
How many strands does RNA have?
one strand
The two phases of protein synthesis (central dogma)
Transcription and Translation
What type of mutation occurred:
ACTCCA --> ACTGGACCA
(original)--> (mutated)
insertion
The type of bond that forms between cytosine and guanine
Hydrogen Bond
Replicate this strand of DNA CTAGGT
GATCCA
What bases are found in both DNA and RNA
guanine, cytosine, adenine
Produced during transcription.
RNA
Adding new bases
insertion
Figured out the the shape of DNA is a double helix.
Watson and Crick
Where does DNA replication take place?
Nucleus
The base is not found in RNA and its replacement.
Thymine, Uracil
The molecule from which information is derived for how to make proteins
DNA
removing bases from DNA sequence
deletion
The rules for base pairing in DNA
Adenine always pairs with Thymine Guanine always pairs with Cytosine
What pairs with Guanine?
Cytosine
What is the sugar in RNA
ribose
What are the building blocks of proteins
amino acids
exchanging one base for another
substitution
What base does DNA not have?
Uracil
Does DNA replication occur before cell division?
YES
The 3 RNA molecules involved in protein synthesis.
mRNA, tRNA, rRNA
The amino acids that are specified by the following codon: AUG
Methionine
What is the danger of a mutation?
coding for a non functional protein
