Answer:
last answer
Explanation:
dna doesn't make carbohydrate. it has no connection with carbohydrates
environment and parasites don't make our genes it's dna. environment can affect it or make some changes like tanning of skin ....
lipids also doesn't have any connection with dna or rna. fatty acids and glycerol make lipids
dna provide genetic code to m-rna which assemble in r-rna with amino acids carried by t-rna and form proteins.
dna involve in protein synthesis by providing genetic code for rna
what exactly affects our look is the genes that we call phenotypes.
This is called the nacreous layer, the pearly layer.
The DNA is packaged... it starts by being wrapped around special protein molecules (histones). This forms a nucleosome.
There are three domains:
the ARCHAEA, BACTERIA, and EUCARYA
oragnisms from ARCHAEA and BACTERIA have a prokaryotic cell structure, whereas organisms from the domain EUCARYA encompass cells wirh a nucleus confining the genetic material from the CYTOPLASM.
and all of this is the answer..good luck
Answer:
A
Explanation:
Because there are two DNA strands in the DNA molecule and they both rotate around each other in a helix formation. So two helixes = double helix.
