Proving DNA
Who determined the specific structure of the DNA double helix
Who is Watson and Crick?
What is the percent of Adenines in DNA if 30% of the DNA contains cytosine?
What is 20%?
The process in which DNA codes for RNA which guides the making of proteins.
What is the central dogma of biology (protein synthesis?
The complementary codon bases of tRNA to the codon mRNA.
What is an anticodon?
Type of point mutation when a stop codon replaces an amino acid codon
What is a nonsense mutation?
Who is Meselson and Stahl?
What enzyme helps break hydrogen bonds in DNA replication?
What is helicase?
The process in which Messenger RNA is made from DNA
What is transcription?
The number of the subunits (rRNA) that come together to form the ribosome
What is 2: large subunit & small subunit?
The trp operon is this type of gene regulation
What is repressible?
Insertions and deletions cause mutations resulting in the ribosome misreading the codons
What are frameshift mutations?
Who is Chargaff?
What protein prevents complementary bases from reannealing or reforming?
What is SSBPs (Single Stranded Binding Proteins)
The process of reading codons to make proteins
What is translation?
The location in which tRNA bind to the site of the ribosome to bring the amino acid.
What is A-site (Active site)
This binds to the operator and blocks transcription
What is a repressor protein?
GGU codes for Glycine. The mutation GGG codes for Glycine. What type of point mutation is this?
Who discovered the fragments of DNA or lagging strand in DNA replication?
Who is Okasaki?
The enzyme needed to connect nucleotides in the leading and lagging strands?
What is DNA ligase?
Sequences that are removed from mRNA during splicing.
What are introns?
The original DNA sequence is ATC. What is the codon read by the ribosome?
What is UAG?
The addition of a molecule to a polypeptide chain is an example of regulation at this level?
What is Post transcriptional regulation
What is the outcome of a harmful mutation in the making of helicase?
DNA Replication cannot occur as DNA cannot be unzipped.
Who created the famous X pattern of DNA using X ray crystallography that helped Watson and Crick's discovery of the double helix structure of DNA?
Who is Franklin?
The enzyme that adds complementary bases to the leading and lagging strands?
What is DNA Polymerase III?
The starting amino acid of a polypeptide chain.
What is Met?
The three three main types of this nucleic acid - specifically RNA - involved in protein synthesis
What is mRNA, rRNA and tRNA?
The operon is an example of inducible regulation in prokaryotes?
What is the lac operon?
Mutations that occur in genes affect the functioning of this?
What are proteins in protein synthesis?
