The illustration represents a part of which of the following types of biochemicals?

7 is dna

and i got 10 wrong but big to the guy with all 20 answers.

Ijust took this test homie, even though it might be too late here are the answers
1. aldehyde
2.polystyrene
3.a
4.lipid
5.protiens
6. peptide bond
7. nucliec acids
8. hemoglobin
9. dipetide
10. butyne
11.-ch2-ccl2-
12. they are isomers
13. six sided ring
14. monosaccaride
15. ch3-ch2-ch2-ch = ch2
16. polyatic acid
17. ch3-co-o-ch3
18. ch3-ch=ch -ch3
19.copolymer
20. 4

so, the answer to your question is number 7 (nucliec acids) btw if you are in k12 post your tests so we all dont have to search like madmen for the answers like i just did.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic 

No is the answer to the question
