Answer:

Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth. Cellulose fibers are long, linear polymers of hundreds of glucose molecules. These fibers aggregate into bundles of about 40, which are called microfibrils.

Kipish [7]

Out of the following given choices;

a.            Valine instead of glutamic acid in the sixth position

b.            Glutamic acid replacing valine in the first position

c.             Extensive amino acid substitutions

d.            Trinucleotide repeats

e.            Frameshift substitutions

The answer is A. this is caused by a mutation in the beta thalassemia genes on one of the 46 human chromosomes (chromosome #11) of the individual. The alpha subunit is normal in people with sickle cell disease. When sickle hemoglobin releases oxygen in the peripheral tissues, the molecules tend to stick together and form long chains or polymers. These rigid polymers distort the cell and cause it to bend out of shape from the normative disc shape.

Determine the dna sequence by analyzing the location of each nucleotide across the four lanes of the electrophoresis instrument.
kaheart [24]

The specific electrophoretic diagram required to determine the DNA sequence is not found here but this technique refers to Sanger sequencing.

<h3>What is Sanger sequencing?</h3>

Sanger sequencing is a technique used in molecular biology and genetics to determine the linear order of nucleotide bases in a given genomic sequence, which is fundamental to identifying alleles in a genome.

This technique (Sanger sequencing) is based on the use of certain analogous nucleotides that stop the process of amplification, which can be subsequently evidenced in an electrophoresis gel.

In conclusion, the specific electrophoretic diagram required to determine the DNA sequence is not found here but this technique refers to Sanger sequencing.

mezya [45]

Answer:

Option (A).

Explanation:

Cell membrane or plasma membrane is made up of lipids and proteins with the small amount of carbohydrates are attached to it. This membrane maintains fluidity and separate cell's environment.

Small non polar and uncharged molecules can easily pass through the cell membrane by the process of diffusion. Carbon dioxide and water are small molecules that can easily pass through the membrane.

Thus, the correct answer is option (A).
