Flashcards in From DNA to Proteins Deck (27):
converts information in a gene to RNA; translation converts information in an mRNA to protein
RNA nucleoside differs from DNA
Uracil, not thymine.
Ribosomal RNA (rRNA)
protein synthesis, main component of ribosomes, structures upon which polypeptide chains are built.
Transfer RNA (tRNA)
protein synthesis, delivers amino acids to ribosomes, one by one.
Messenger RNA (mRNA)
protein synthesis, orders the delivery of amino acids to ribosome(tRNA). transcribes the information
from mRNA to protein
A multistep process by which genetic information encoded by a gene is converted into a structural or functional part of a cell or body
links RNA nucleotides into a chain, in the order dictated by the base sequence of a gene, aka adds more nucleotides to the end of a growing transcript
binding site in the DNA, starts the transcription
Nucleotide sequence that are removed from a new RNA
sequence that stay in the RNA
one gene can encode different proteins
a "word", made of four nucleotides, a code for a particular amino acid
The 64 possibilities of codes total.
UAA, UAG, and UGA
a triplet of nucleotides that base pairs with an mRNA codon. part of the tRNA attachment sites
converts information carried by an mRNA into a new polypeptide chain. second part of protein synthesis.
one nucleotide and its partner are replaced by a different base pair
mutation, in which one or more bases is lost, is smaller than a chromosomal deletion.
segments of DNA that can insert themselves anywhere in a chromosome.
Where is RNA made
Same amino acids but no affect of mutation
Base Pair Substitution
One nucleotide and particular replaced by another pair
