Dna and rna differ in all but the following ways. a) dna is double-stranded, while rna is single stranded b) rna uses the sugar ribose in its backbone, while dna uses deoxyribose c) dna contains the base uracil, while rna can move around the cell d) dna is found in choromosomes in the nucleus, while rna can move around the cell

DNA and RNA are almost identical.

There are three fundamental differences between DNA and RNA:

* RNA is a single-stranded nucleic acid, while DNA is double-stranded.

* RNA has ribose sugar, while DNA has a deoxyribose sugar instead.

* RNA has a uracil base, while DNA has a thymine base.

Moreover, DNA is present in the nucleus of each cell, while RNA is capable of moving around from the nucleus to ribosomes (thus RNA can move around the cell).

We then note that option C has interchanged the two bases, while the other three options are all correct differences.

CONCLUSION: C, because DNA contains the base thymine, while RNA contains the base uracil.

the answers are a and c

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
