What is the sequence of bases on DNA strand b from left to right<br> (See picture)
VLD [36.1K]

Answer:

DNA sequence from left to right

T G A G G A C T T

Explanation:

There are four DNA nitogenous base they include thymine, guanine, cytosine and Adenine. The Nitrogenous bases are complementary that is Adenine is complementary to thymine and cytosine is completely to quanine and they both can replace each other in this manner A-T,C-G and it means that Adenine can pair with thymine and cytosine can only pair with guanine. DNA is known as Deoxyribonucleic acid. DNA sequencing are shown usually from the 5' end to the 3' end . The sense strand in DNA is used in DNA sequences and also it has the antisense strand and also called the coding strand and the non-coding strand are information are contained in the sequence

The distance between two charges and is r, and the force between them is F. What is the force between them if the distance betwe
dimulka [17.4K]

The force between them if the distance between them is doubled is a. F/4

Explanation:

  • To find the answer, we can use Coulomb's law where it is defined as the force between two point charges is directly proportional to the magnitude of the point charges and proportional inversely to the distance between them.
  • The equation can be written as, F= K \frac{ q_{1} q_{2} }{r^{2} } where k is the Coulomb constant, q_{1}  q_{2} are the point charges, and r is the distance between these two point charges.
  • To find the answer to this question, just substitute 2r in the place of r hence, you will get \frac{F}{4} as the new force when the distance is doubled.
