Homework Answers
Answer:All of the following steps occur in protein synthesis,i.e.,
1.mRNA sequence is same as that of DNA template strand.
3.Protein synthesis process requires expenditure of energy.
4.The gene must unwind before mRNA can be synthesized.
the following step do not occur in protein synthesis
(2).aminoacids joined together by ribosomes.
since they are joined together by peptide bonds(covalent bond) to form polypeptide chain and carried to ribosomes where protein synthesis occur.

What role does mRNA play in the process of protein synthesis? Choose all that apply. Select one or more: Every three nucleotides binds an amino acid It opens up the DNA strand for transcription to occur ] c. It is a template for the arrangement of tRNAS 1 d. It determines the order in which amino acids are added to the growing protein e. It copies DNA to be used in later steps
Arrange the following steps of protein synthesis in the correct order
Q1 Arrange the following steps of protein synthesis in the correct order (Number in the correct order). mRNA is generated. DNA unwinds to become single stranded. mRNA binds to a ribosome. Ribosome links amino acids together. RNA anticodon basepairs with mRNA codon. mRNA is transported out of the nucleus. protein is complete!
