Question

PLEASE HELPPP!!!! I DON'T UNDERSTAND ANY OF THIS!!!!
1. The codons that signal the end of a polypeptide chain are called _____. (1 point)
promoters
introns
exons
terminators

2. Which of the following occurs after a codon and anticodon form hydrogen bonds? (1 point)rRNA and protein combine to form a ribosome.
A three-base sequence binds to a peptide.
A dehydration reaction forms a peptide bond.
tRNA carrying an amino acid binds to the ribosome.

3. During translation, the type of amino acid that is added to the growing polypeptide depends on the _____ (1 point)codon on the m

Answer 1

Q1: Another word for the end of a polypeptide is "terminus". I hope this is enough of a clue.The last codon is also known as the stop codon - there are three which code for the stop.
Q2: Ribosomes are formed in the cell prior to translation so it won't be after the codon and anticodon bind. The tRNA is also present at the ribosome when the codon and anticodon bind so it can't be that either. The bonds between amino acids in a polypeptide are known as peptide bonds and this happens after the codon and anticodon bind.

Q3: I can't see the end of the question!

Answer 2

codon on the mRNA and the anticodon on the rRNA.
anticodon on the mRNA and the anticodon on the tRNA.
anticodon on the rRNA and the codon on the mRNA.
codon on the mRNA and the anticodon on the tRNA. end of the last Q

Answer 3

codon on the mRNA and the anticodon on the tRNA
