Compare and contrast dna and rna. what is similar and different between them?

questions listed below.
what is the function of dna and rna?

what is the structure of dna and rna?

both dna and rna are made up of sugars, but what is difference?

what base pairs do dna and rna share, and what is different?

for number 4 the answer The sugar in DNA is deoxyribose and The sugar in RNA is ribose

Explanation:

1.DNA provides the code for the cells activities, while RNA converts that code into proteins to carry out cellular functions. The sequence of nitrogen bases (A, T, C, G) in DNA is what forms an organism's traits

2.DNA nucleotides are made up of a sugar (deoxyribose), base (adenine, guanine, cytosine, thiamine) and phosphate. RNA nucleotides are made up of a sugar (ribose), base (adenine, guanine, cytosine, uracil) and phosphate.

3.Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose.

Explanation:

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.

explanation:

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
