Answer 1

• transcription
• translation

Question 2

Answer 2

• sequences of bases in a gene that don’t code for amino acids
• get removed out of mRNA molecules after transcription

Question 3

Answer 3

• sequences of bases in a gene that code for a sequence of amino acids

Question 4

what are stop and start codons?

Answer 4

• start codon at the start of every gene
• enables the ribosome to attach
• stop codon at end of every gene
