Answer:

All the options are correct.

Explanation:

In the given question, the model of the DNA is not given but assuming that the DNA of Eukaryotes would have been provided therefore based on the previous knowledge this can be answered.

The DNA molecule is made up of two strands of nucleotide monomers which are composed of four types of nitrogenous bases (A, G, T, C), a 5 carbon sugar and a phosphate group.

The sugar and phosphate group forms the backbone of the DNA molecule and the nitrogenous bases are present inside of the backbone which is joined to the Complementary base pair via hydrogen bonds. 2 hydrogen bonds are formed between A and T and 3 hydrogen bonds are formed between G and C.

Thus, all the options are correct.

Based on the information above, which of the following is true about the process in which the genetic code stored in DNA is used
DanielleElmas [232]

Answer:

D.This process requires the interaction of several different cellular structures,

Explanation:

We don't have the information above. However, this process occurs in all cells, and it requires energy. Semi-conservative refers to the fact that, during DNA replication, each new molecule of DNA is made up of one strand of the original DNA molecule and one strand of a new molecule.

The synthesis of proteins from the information in an mRNA molecule does require several structures in the cell, including the nucleus, ribosomes, endoplasmic reticulum and Golgi apparatus.

LekaFEV [45]

Answer:

Muscular Dystrophy : 50%

Breast cancer: 50%

Explanation:

Muscular Dystrophy (linked to X):

1/2 (mother) x 2/2 (father) = 2/4 (50%) chance of having an affected child with MD

Breast cancer (autosomal dominant disorder):

1/2 (mother) + 0 (father) = 1/2 = 50% chance of having an affected child with breast cancer

What causes rough endoplasmic reticulum to look "rough" under a microscope?
jolli1 [7]

Answer:

Rough endoplasmic reticulum looks "rough" under a microscope because it has ribosomes attached to its surface.

Explanation:

Rough endoplasmic reticulum (RER) is a membrane organelle found in the cytoplasm of eukaryotic cells, which has ribosomes attached to its outer surface. Hence the name, rough endoplasmic reticulum. It has an important role in the synthesis of proteins. In ribosomes, the proteins are synthesized. The smooth endoplasmic reticulum (SER) does not contain ribosomes. It has an impotant role in the synthesis and storage of lipids. The proteins that are synthesized in the ribosomes are packaged into vesicles and transported to the Golgi apparatus by the rough endoplasmic reticulum. The Golgi apparatus which is located near the RER, modifies, transports and packages proteins for delivery to targeted destinations.
