transcription
|
the synthesis of RNA on a DNA template
|
|
messenger Rna(mRNA)
|
a type of rna, synthesized from dna, that attaches to ribosomes in the cytoplasm and specifies the primary structure of a protein
|
|
translation
|
synthesis of a polypeptide using the genetic info encodede in a mRNA molecule. there is a change of "language" from the nucleotides to amino acids
|
|
ribosomes
|
organelle-site of protein synthesis
|
|
RNA processing
|
modification of RNA before it leaves the nucleus, a process unique to eukaryotes
|
|
primary transcript
|
initial rna transcript, also called pre-mRNA when transcrribed from a protein-coding gene
|
|
tripled code
|
a set of 3 nucleotide long words the specify the amino acids for polypeptide chains
|
|
template strand
|
DNA strand that provides the template for ordering the sequence of nucleotides in a RNA sequence
|
|
reading frame
|
the way a cell's mrna translating machinery groups the mrna nucleotides into codons
|
|
