codons and the genetic code
3
what does AUG code for?
Methionine(start amino acid)
What is translation meant to synthesize?
protein
which is smaller?
RNA
what are the 2 ends of DNA or RNA known as?
5' and 3'
what does UUU code for?
phenylalanine
what attaches to the mRNA once it leaves the nucleus.
Ribosome
which is double stranded?
DNA
what are the 3 stop codons?
UAA,UGA,UAG
what codons can make Tyrine?
UAU,UAC
what 2 types of RNA are involved in this?
tRNA,mRNA
which one is used for storing genetic information.
DNA
What is the start amino known as?
methionine
What codon can form alanine?
GC any letter
where does the polypeptide go after synthesis?
other organelles for further processing
what are the 3 types of RNA
tRNA,mRNA, rRNA
why are codons redundant?
single/double nucleotide wouldn't allow to code for all 20 amino acids. Also its for protection and prevention from mutation
What does ACU code for?
threonine
explain the steps of a polypeptide forming.
mRNA links to a tRNA that has an amino acid on it, the tRNA keep linking to the mRNA chain until a stop codon is reached.
what is the nitrogenous base that is replaced in DNA?
Thymine replaced by uracil
