Which components bond with the nitrogenous base, guanine, in a section of double-stranded DNA? Options:

Ribose sugar and uracil

Deoxyribose sugar, phosphate, and Thymine

Guanine, cytosine, and phosphate

Cytosine and deoxyribose sugar

 Cytosine and deoxyribose sugar

Explanation: : Remember the base pairing rules: cytosine with guanine and adenine with thymine, in equal amounts. To compliment the given base,, you'd have to choose the nucleotide that would pair with it, attached to a phosphate-sugar backbone. I'm not quite sure why they didn't include phosphate in that option, but it's the only possible one. Guanine couldn't pair with any of the other listed options.

Hope this helps,

Cytosine and deoxyribose sugar

Explanation:

this answer is right i got a 100% on my 7.01-7.03 quiz

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
