Which of the following monomers would be used to make the double helix of a DNA molecule?

Question

anonymous · Answer

attachment

australopithecus · Answer

Which one do you think is a monomer of DNA

australopithecus · Answer

Hint: one of them is an amino acid

australopithecus · Answer

The other is a nucleotide base

anonymous · Answer

the second one

australopithecus · Answer

Why the second one?

anonymous · Answer

idk i suck at bio

australopithecus · Answer

Bio is just memorization, you just need to study more

australopithecus · Answer

Do you know what a monomer is?

australopithecus · Answer

and a polymer?

anonymous · Answer

Polymer means many monomers. right?

australopithecus · Answer

yes, a polymer is a thing that is made up of many monomers which are similar units

anonymous · Answer

polymers are macromolecules or large molecules

australopithecus · Answer

yes they can be small too

australopithecus · Answer

But generally speaking they can be very large, DNA is a polymer, now both of these chemicals are monomers, and you are aware that DNA is made up of 4 bases right?

anonymous · Answer

yes

Adenine 
Thymine
Guanine 
Cytosine

australopithecus · Answer

well nitrogenous bases, basically what I'm getting at is DNA has 4 different monomers thus logically you should have picked the more complicated looking one, the second one is an amino acid, which is very non descriptive on its side chain (R just means various carbon chain)

australopithecus · Answer

DNA has A sugar monophosphate backbone

australopithecus · Answer

with a nitrogenous base attached to it

australopithecus · Answer

which can be one of those 4

australopithecus · Answer

best to just say sugar phosphate backbone though

anonymous · Answer

ok

australopithecus · Answer

Proteins are made up of amnio acids which generally look like what the second chemical is

anonymous · Answer

so the answer is the first picture

australopithecus · Answer

the only thing that differs on them is the side chain (denoted by R) and there are about 20 amino acids naturally occurring

australopithecus · Answer

yes

anonymous · Answer

ok

australopithecus · Answer

would you like me to provide you with a video resource that goes over this stuff?

anonymous · Answer

sure

anonymous · Answer

ok i have one more question for you

australopithecus · Answer

here is a good text book, for cellular biology but you should find everything you ever wanted to know here https://www.ncbi.nlm.nih.gov/books/NBK9839/

australopithecus · Answer

give me a second

australopithecus · Answer

I have videos as well I just need to find them Im combing through my old bio course

anonymous · Answer

What biological macromolecule is made up of monomers is the first picture shown at the top made of is it a  Nucleic acid a protein a fat or a carbohydrate monomer

australopithecus · Answer

fats aren't polymers

australopithecus · Answer

firstly although they have a distinct structure

anonymous · Answer

i think it is a nucleic acid

australopithecus · Answer

yes that is correct the first picture is nucleic acid

anonymous · Answer

ok thank you

australopithecus · Answer

here these are videos and they are fairly informative

anonymous · Answer

ok thanks and i got a 83 :)

australopithecus · Answer

I would recommend watching the videos on lipids, nucleic acids and all that stuff it will help you a lot in the future and even if it doesnt it is good to know this stuff

australopithecus · Answer

It will give you a greater appreciation for life

anonymous · Answer

ok i will after i do my history hw

anonymous · Answer

pp1 is the first video?

anonymous · Answer

10 videos
