Biology

RNA, transcription, translation

QuestionAnswer
What are proteins made of? Amino acids
How many different types of amino acids are there? 20
What is protein synthesis? The process in which a cell makes portions based on the message contained within its DNA.
where is DNA located? Nucleus
Where are proteins made? Ribosomes
What does 3 bases of code make? A codon
When the bases of code build up and form a long chain- what is that called? A protein
Where does transcription take place? In the nucleus
What is transcription? The genetic information from a strand of DNA is copied into a strand of mRNA
Why does transcription take place in the nucleus? DNA is located in the nucleus
Why does a cell need to carry out transcription in order to make a protein? SO the exact genetic information is copied into a strand of mRNA, which is the MESSENGER that carries out the information so a protein cane be made.
During transcription- what does RNA polymerase do? Separates into two strands of DNA double helix and uses a gene in one DNA strand as a guide to make mRNA.
What does mRNA do? carries code from the DNA in nucleus to where protein synthesis occurs- the ribosomes.
What does tRNA do? has anticodon for mRNA to bind to to make code.
