Question

What is the role of DNA molecules in the synthesis of proteins?

1) They catalyze the formation of bonds between amino acids

2) They determine the sequence of amino acids in a proteins

3) They transfer amino acids from the cytoplasm to the nucleus

4) They supply energy for protein synthesis

In all living cells, DNA controls cellular activities by

1) determining the order of amino acids in protein molecules

2) regulating the concentration of molecules on both sides of the cell membrane

3) varying the rates of starch synthesis

4) coordinating active and passive transport

Answer 1

The  answers  are  2 &amp;1

Answer 2

They determine the sequence  of amino acids in proteins.

Answer 3

DNA is like a blueprint so answer number 2 is right for the 1st question.

Number 2 im not sure but its definitely not number 4

Answer 4

Q1) 2

Q2) 1

Answer 5

The answers to your questions are:-

What is the role of DNA molecules in the synthesis of proteins?

A)They determine the sequence of amino acids in a proteins

DNA are actively involved in protein synthesis by trancription of m-RNA

In all living cells, DNA controls cellular activities by

A)Determining the order of amino acids in protein molecules which is done by translation during protein synthesis.
