Vocab
Shape of DNA.
Unzips the DNA molecule to start replication.
Helicase
The end product of transcription.
mRNA
DNA stands for Deoxyribonucleic Acid.
True
Proper name for Adenine, Guanine, Cytosine, Thymine. One of the three components of DNA.
Nitrogenous Base
A single strand of genetic information present in all living cells.
RNA
Lays down the RNA primer needed for replication.
RNA Primase
The end product of translation.
Amino acid chains
A codon is a string of eight nucleotides that code for a particular amino acid.
False - three
Must be on a replicated strand of DNA before new bases can be added
RNA Primer
A double ringed structure used to build genetic material, examples are adenine and guanine.
Purine
Connects to the RNA primer and adds DNA bases to create a complementary DNA strand.
DNA Polymerase III
Replicate this DNA strand to create a complementary strand. TAG | ACT | CTA | GCG
ATC | TGA | GAT | CGC
Uracil replaces cytosine in RNA.
False - Thymine
How many amino acids can a single tRNA carry?
One
A single ringed structure used to build genetic material, examples are thymine and cytosine.
Pyrimidine
Bonds together lagging strands into one strand.
Ligase
Transcribe this DNA molecule.
GGT | ACA | CCC | TCT
CCA | UGU | GGG | AGA
DNA replication is considered conservative, which means one DNA has both original strands, and another has both copied strands.
False - semi-conservative
The sugar used in RNA.
Ribose
The idea that DNA becomes RNA which becomes proteins.
Central Dogma
Removes the RNA primer to allow for DNA bases to be added.
DNA Polymerase I
Translate this string of RNA into amino acids.
CCA | UGU | GGG | AGA
Pro | Cys | Gly | Arg
The anticodon is bound to a tRNA which also brings the appropriate amino acid.
True
A start codon codes for which amino acid?
Methionine
