The information carried by a dna molecule is in __________.
Papessa [141]

Answer:

Sequence of nucleotides in the DNA strand

Explanation:

Deoxyribonuceic acid or DNA is a biological material that stores the genetic information of an organism.

DNA encodes the information through the order or sequence of the nuceotides along each strand. Organisms differ from one another because their respective DNA molecule have different nucleotide sequences and consequently, carry different biological instructions.

A DNA strand consists of two polynucleotide chains, composed of four nucleotide subunits. Each of these chains is known as DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together. DNA nucleotides are composed of a 5-carbon sugar (Deoxyribose) to which are attached one phosphate group and a nitrogenous base (Adenine, Guanine, Cytosine and Thymine). The nucleotides are covalently linked together.

An inhibitory stimulus has occurred. B. Chemically gated potassium channels have opened. C. Excessive potassium has diffused out
andrezito [222]

Given question is incomplete. Complete question has been attached.

Answer:

C. Excessive potassium has diffused out causing hyperpolarization.

Explanation:

The nerve action potential can be divided into following stages:

  • Stimulus is detected by the cell in resting stage.
  • Sodium channels in the membrane open from where influx of sodium ions occur which is called depolarization
  • After a while, sodium channels close and potassium channels open from where efflux of potassium ions occur which is called repolarization.
  • The membrane potential further lowers due to continous efflux of potassium ions which is called hyperpolarization.
  • After a while potassium channels close and membrane returns to its resting stage.

In the given figure, stage 4 depicts hyperpolarization because the membrane potential has dropped to the lowest point below -70mV. Hence, option C is correct.
