The answer is the base sequence of gene's promoter.
DNA is a two-stranded helix. One strand is called a template strand, the other one is called a coding strand. The template strand is copied into mRNA, and the coding strand is complementary to the template strand. RNA polymerase, an enzyme responsible for transcription, has to recognize the right strand before transcription begins. So, it recognizes one or more short sequences on the coding strand. This is the base sequence of gene's promoter. Thus, the complementary strand is the template strand.
Mercury is a barren planet with little atmosphere. In many regards it is similar to our own moon. However, it is also very close to the Sun, so humans will have to set up bases in craters or near the Poles to avoid being blinded.
Answer:
A female Drosophila of unknown genotype was crossed with a white-eyed male fly, of genotype (w = white eye allele is recessive, w+= red-eye allele is dominant.) Half of the male and half of the female offspring were red-eyed, and half of the male and half of the female offspring were white-eyed.If the trait is dominant, one of the parents must have the trait. Dominant traits will not skip a generation. If the trait is recessive, neither parent is required to have the trait since they can be heterozygous.The female fly had to be heterozygous, Xw+ Xw.
Explanation:
Answer:
Option (C).
Explanation:
Membrane potential may be defined as the difference in the electric potential of the inside and outside of the cell. The resting membrane potential of neuronal cell is -70mV.
Pufferfish contains tetrodotoxin that blocks the voltage gated sodium channels. The movement of sodium ions inside the cell causes the depolarization of cell and makes the cell membrane potential towards more positive. This tetrodotoxin causes the normal resting potential but the cell are not able to depolarize if the stimulus is given to the cell.
Thus, the correct answer is option (c).
Answer:
Phospholipid bilayer
Explanation:
Liposomes are vesicles are spherical in shape. They consist of at least one phospholipd bilayer most especially phosphatidycholine. Liposomes are artficial vesicles similar to a membrane, because it has an hydrophilic core surrounded by a hydrophobic lipid bilayer.
Liposomes are artificial prepared and are used for the transportation of substances like drugs and nutrients between cell parts, outside of the cell and into the cell.
In liposomal drug delivery, the liposome fuses with other internal cell membranes at the site of action and releases its liposomal content.
