protein synetheis Flashcards
(10 cards)
proteins are made of chains of..
amino acids
what is rna base made of
-phosphate, nucleotide, sugar
what bases pair with what in transcription
thymine+ adenine
cytosine+guanine

uracil
where does transcription take place
-nucleus
what is Dna
a double helix that is a chemical of which genes are made
what what can cause genetic mutations
–ciggarette smoke containing carcinogens
-ionising radiation
-mutagen
why will a genetic mutation not affect a mutation (to do with DNA)
A large portion of DNA is non-coding, meaning it doesn’t directly translate into proteins.
why will a genetic mutation not affect a mutation (amino acids)
Multiple codons can code for the same amino acid. If a mutation changes a codon to one that codes for the same amino acid no change will occur
