Embedded in the cell membrane and helps substances move across the membrane

1 answer:

6 0

Cell membranes contain membrane proteins that allows all the interaction that occurs within the cell. It makes the cell membrane selectively permeable because of its characteristics as being fluid or its fluidity which means to say that they can move freely within the lipid bilayer. The membrane proteins can also be stored in the lipid bilayer together with the enzymes. It cannot be denied that membrane proteins have a lot of functions based on its type. They can be integral proteins, peripheral proteins and lipid bound proteins.

What is the difference between diffusion and active transport?

zysi [14]

Answer:

The difference between diffusion and active transport are as follows:-

If the frequency of one allele in a population is 0.7 in a population with two alleles at a particular locus, what is the freque

Effectus [21]

If the frequency of one allele in a population is 0.7, then the frequency of the alternate allele is 0.3.

Allele frequency is determined by dividing the number of times the allele of concern is seen in a population by the total number of copies of all the alleles at that specific genetic locus in the population.

In case all the allele occurs at the same frequencies in sperm cell and eggs cell, and gametes bond together accidentally to produce zygotes, then the Possibility that any two alleles will combine to form a particular genotype equals the product of the allele frequencies.

How is an RNA molecule different from a DNA molecule?

andreev551 [17]

Answer:

RNA is single-stranded and composed of nitrogenous bases, a phosphate group, and pentose sugar.

Explanation:

RNA is different from DNA because instead of having two matching bases; it is only made of one strand of nitrogenous bases. These bases are attached to the phosphate, which holds the whole strand of RNA together. The sugar acts as a carrier for the bases. The sugar in RNA is known as ribose and contains 5 carbon molecules. This is why it is called pentose sugar.
