Why do ribosomes attach to the endoplasmic reticulum?

Biology
1 answer:
Gre4nikov [31]3 years ago
8 0

<span>Ribosomes are known to be the protein synthesizer of the cell and the attachment of the ribosomes to the membrane of the endoplasmic reticulum is to make it rough endoplasmic reticulum. However, the process of protein synthesis usually starts when mRNA moves from the nucleus to ribosomes on the surface of the rough endoplasmic reticulum.</span>

Imagine a protein that has been engineered to contain a nuclear localization signal, a nuclear export signal, a C-terminal perox
Masja [62]

Answer:

This sequence would target the peroxisome

Explanation:

  • When the protein  is made it will be able to target several organelles in the cell
  • However, the C-terminal sequence is the last sequence transcribed and when the protein is complete this sequence will be the sequence used for targeting the specific organelle
  • in this case, the C-terminal sequence targets the peroxisome

Suppose that in unicorns, two autosomal loci interact to determine the type of tail. One locus controls whether a tail is presen
Nina [5.8K]

Explanation:

As you can see in the picture below, this is a dihybrid cross with a twist.

We can accomplish that mutually parentages are heterozygotes for both characters because the genotypes are  

9 unicorns with curly tails (shown in green)

3 with straight tails (shown in red)

3  curly tales trait carriers with no tail (shown in dark blue)

1  straight tail trait carriers with no tail ( shown in light blue)

If this was an ordinary case of the dihybrid cross, we would get a 9:3:3:1 phenotype ratio.

However, since the first trait, the presence of the tail, is affecting the other trait, the trait texture, the ratio is altered.

\frac{1}{4} of the offspring (genotypes tt C_   and tt SS) has no tail, therefore we cannot observe the texture of the tail (some of the tailless individuals have Curly alleles -blue squares marked with green, some of them have Straight alleles -blue square marked with red ).

Therefore, the altered ratio is  \frac{1}{2} curly tails,\frac{1}{4} straight tales, \frac{1}{4} tailless

If your body is capable of making only certain amino acids, how do we get the essential amino acids we need?
Gelneren [198K]
Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

The table below shows the dimensions of two colored cubes.
Lelechka [254]

Answer: The correct answer is black because the product of its side and mass is lower.

Explanation: Density of a substance is defined as the mount of matter that can be stored in a given volume.

Mathematically,

Density=\frac{Mass}{volume}

As, density is inversely proportional to the volume of the substance.

The substance will be more denser if it has less volume and it will be less denser if the volume is more.

We are given two cubes having different sides.

Volume of the cube is calculated by using the formula:

V=a^3

where, a = side of the cube.

Black: The side of this cube is 2 and volume will be = 2^3=8cm^3

Yellow: The side of this cube is 3 and volume will be = 3^3=27cm^3&#10;

As, the volume of black cube is less. So, this cube will be more denser.

Density of black cube: \frac{48}{8}=6g/cm^3

Density of Yellow Cube: \frac{135}{27}=5g/cm^3

Hence, black cube will be more denser  because the product of its side and mass is lower.
