Answer:

These are just the answer key. You will have to fill in the lower half of the questions yourself. I did not consider 32% and 1.6% approximately the same but the answer key did.

Hope this helps:)

Explanation:

The box’s measurements are: length = 50 cm, width = 25 cm, and height = 25 cm. The measurements of the block are: length = 10 cm, width = 10 cm, and height is 5 cm.

Out of 100 marble drops or shots, the marble hit the block 32 times.

volume of the box = 50 × 25 × 25 = 31250 cm 3

volume of the block = 10 × 10 × 5 = 500 cm 3

Ratio = 500/31250 = 0.016 × 100 = 1.6%

The volume of the block is 1.6% of the volume of the box

Ratio = 32 hits/100 shots = 0.32 × 100 = 32%

The block was hit 32% of the time.

Percentages will be similar and both be small percentages

Answers

Answer:

The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.

Explanation:

A in Biology class last year.

DNA is the genetic material of many organisms. The primary function of DNA is to store the genetic information that results in protein synthesis.

What is DNA?

DNA or deoxyribonucleic acid is the nucleic acid that includes the instruction and the information that codes for protein synthesis. It is a crucial part of hereditary that passes the genetic traits from one generation to another.

The major role that it plays in an organism is to store the genetic code and information so that it can be used to synthesize proteins through the process of transcription and translation.

Therefore, DNA stores genetic information.

PLEASE HELP -- Imagine protein X, destined to span the plasma membrane. Assume that the mRNA carrying the genetic message for protein X has already been translated by ribosomes in a cell culture. If you fractionate the cells, in which fraction would you find protein X? Explain by describing its transit through the cell.

Answers

Answer:

Protein X would be ultimately present in the subcellular fraction containing membrane fragments

Explanation:

It is possible to trace the synthesis and transport of a membrane protein by the following steps:

1- The amino acids of the membrane protein are joined together in the ribosome to form a polypeptide chain (in this case, the protein X).

2- A signal sequence of the growing polypeptide produces the binding of the ribosome to the membrane of the endoplasmic reticulum (ER) and the insertion of this polypeptide chain into the ER.

3-The protein is released into a vesicle from the ER to be exported to the Golgi complex.

4- The membrane protein is transported by the Golgi complex to the cell membrane by the formation of a secretory vesicle that fuses with the plasma membrane, thus being finally embedded in the lipid bilayer.

Protein X should be present in the subcellular fraction that comprise of membrane fragments

The fraction that should be measured the protein X:

Here the synthesis should be traced and the membrane protein transport should be applied by using the following steps:

Here the amino acids of the membrane protein should be connected together so that the polypeptide chain should be created. A signal sequence with respect to the polypeptide should be grown that generated the ribosome binding. Now the protein should be relased into the vesicle. At last, the protein of the membrane should be transported to the cell membrane.
