DNA Flashcards
To speed up the process of DNA replication we use what?
several replication forks at once
Each step of replication uses what?
a different enzyme
simple cell - replication happens at what kind of fork?
one replication fork down whole DNA chain
complex cells - replication happens at what kind of fork?
many replication forks sitameously
what is a gene?
sequence of DNA that codes for a protein and determines a trait
why is transcription necessary?
duplicate DNA without removing from nucleus
where does transcription occur
nucleus
how is mRNA similar to the DNA it copies?
complimentary copy
what is a ribosome?
organelle that builds proteins
where does translation occur?
ribosomes
what is the purpose of translation?
to translate DNA into protein language
what is the name for the nucleotides that code for a specific amino acid?
codon
what type of molecule brings the amino acids to the ribosome?
tRNA
protein synthesis is the process of what?
making protein
proteins are long chains made up of what?
amino acids
