Yeah yeah so :D,
Large polar molecules can only cross the membrane with the help of protein named channel protein and carrier protein.
So, this both proteins act like a gate, the large molecules enter the protein and the protein let the large molecules in to the membrane. (see the picture so that you can understand more, its carrier protein)
the only difference between channel protein and carrier protein is, channel proteins has fixed shape while carrier protein can flip.

Sam, Tim, Bella and Joshua on the grounds that the red in Lisa is the partial blindness and they're the main individuals with the full shading red shaded.

Explanation:</u></h3>
Red green visual impairment is a x connected characteristic, which implies that it is found on the X chromosome. X connected attributes are frequently latent, and this is the reason they for the most part appear in guys, for example, the instance of red green colorblindness.
A male has just a single duplicate of the X chromosome, so if a passive x connected characteristic is available, he doesn't have the alternative of the prevailing rendition of the quality to appear.
A latent X connected attribute can introduce itself in a female, yet since she has two X chromosomes, she would need two duplicates of the passive quality for it to introduce itself.
This is the reason visual impairment is less normal, yet at the same time conceivable in females. I trust this encourages you with your family.

Explanation:
Answer:
A DNA fragment with sticky end sequence TGGCA will bind with another DNA fragment with sticky end sequence ACCGT.
Explanation:
When a DNA strand is separated by the restriction endonuclease, it forms two separate single strands. These strands or cuts are known as sticky ends as they are detached from the complementary pairs.
These cuts of DNA are without complementary pairs and when they find suitable base pair, they get attached to it. These sticky ends are allowed to fix with the complementary base pairs during PCR/ polymerase chain reaction.
They are called sticky ends as they are ready to stick with the complementary base pairs of nucleotides.
