1 In the diagram below label the DEOXYRIBOSE SUGAR MOLECULE

1. In the diagram below label:

the DEOXYRIBOSE SUGAR MOLECULE WITH A “S”;

the PHOSPHATE GROUP with a “P”;

the NITROGENOUS BASES with appropriate letters of your choosing;

a hydrogen bond and a covalent bond;

the 5’ and 3’ ends.

2. In the diagram above, CIRCLE ONE nucleotide.

3. In DNA, the nitrogenous base C always binds to the nitrogenous base ____, and the A always bonds to ____.

4.In RNA, the nitrogenous base A always binds to the nitrogenous base ____.

5.If the DNA code was ATGCTAGAT, what would the mRNA codons be?

                        ___ ___ ___   ___ ___ ___   ___ ___ ___

6.What do we call this process of making mRNA from the DNA coding strand?

7.What would be the tRNA anticodons for the mRNA in question 5?

                        ___ ___ ___   ___ ___ ___   ___ ___ ___

8.Do we use the mRNA codons or the tRNA anticodons in order to use the coding chart to tell us what amino acids were coded for by the DNA strand?

9.Using a coding chart, what amino acids are coded for by the DNA?

            __________   ___________   __________

10. What type of bond holds the amino acids together as the protein is being synthesized?

11. What do we call the process where mRNA, tRNA and ribosomes work together to put the proper amino acids in order to make a protein?

Solution

For question 1 and 2 I am unable to see any diagram.

Question 3: In DNA, nitrogen base Cytosine (C) always pairs with base Guanine (G) and base Adenine (A) always adds to base Thiamine (T).

Question 4. In RNA, Adeninine pairs with Uracil (U).

5 . mRNA code will be - UACGAUCUA.

6. The process of formation of RNA from the DNA is known as transcription.
