If the base sequence of one strand in a DNA molecule is GACACATAGCAC, then the base sequence of the other strand must be: Please choose the correct answer from the following choices, and then select the submit answer button. CTATGAATAGTA TCACACGCTACA. CTGTGTATCGTG. AAATTTCCCGGG GACACATAGCAC.

CTGTGTATCGTG

Explanation:

According to the rule of complementary base pairing proposed by Erwin Chargaff, the Adenine binds the Thymine and the Cytosine binds the Guanine.

In the given question,

if the base sequence of one strand will be- GACACATAGCAC

            The complementary strand will be-  CTGTGTATCGTG.

This option is chosen as this option fits the complementary base pairing rule and the is the most appropriate option.

Thus, CTGTGTATCGTG is correct.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

i tried the eyeshadow trick you told me about and it worked so good i i did a yellow going into orange colors and it was bright and you could see it on my eyes
