For a species with a haploid number of 15 chromosomes, how many different combinations of maternal and paternal chromosomes are
babymother [125]
The answer is:  " 32,768 " .
___________________________________________
Explanation:
__________________________________________________________
 →  2ⁿ  = ? ;  {that is: "2" , raised to the "n th" power, equals {<u>what value</u>} ?
___________________________________________
 → Note that "n" is the haploid number, which is: 
                           "15" (value given within this very question).
__________________________________________________
→ So we plug in "15" for "n" ; to obtain the "final value" —
                                                          which is the answer.
__________________________________________________
           →  As such:  " 2¹⁵ = 32,768 " .  (using scientific calculator online).
___________________________________________________
           →  The answer is:  " 32,768 " .

A is a DNA sequence where RNA polymerase binds and begins the process of transcription. A is a DNA sequence that binds regulator
WARRIOR [948]

<u>Answer:</u>

A is a DNA sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.

<u>Explanation:</u>

Background Knowledge:

DNA contains genes which is a particular segment of DNA. A gene usually has regulatory regions and a structural region.

Promoter: The regulatory region located to the 5 prime end of coding strand of the gene which is called as promoter that controls the binding RNA Polymerase during transcription.

The Terminator is the other regulatory region, located to the 3 prime end of coding strand of the gene. The terminator region causes RNA polymerase to stop transcription.

Structural region is the region present between the promoter and terminator.

Answer of the question is:

A is a DNA sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.

I need help please thank you.
Fantom [35]
Hey!
8= B : adenine with thymine , guanine with cytosine.

9= False : its not single , *dual* helical structure.

10= Every humans' DNA is different but its as similar as our relatives' DNAs as far as i know so its False.

11 = The two backbones of the DNA molecule consists a deoxyribose sugar ^with 5 carbone^ and a phosphate so the correct answer is B

12= Procaryotes' Genomes are simpler- structured than eukaryotes' so procayotes DNA is 1/1000 of eukaryotes.I couldnt translate the options correctly (im not native sorry) but i think its B according to my knowledge of that XD

13= the amount of adenine, guanine, thymime and cytosine must be same so the correct option is %40as well.

Hope it helps!!!
