Outside the plasma membrane there is presence of glycoprotein which is a series of polysaccharides to form the cell coat and is used for ID or cell recognition. Each individual has a unique special code for the glycoprotein.
Assuming this is an EMT Question
Never disclose any information over the radio that can be used to identify the patient including his name. Use general terminology.
Answer:
The nucleic acid DNA is an organic compound. DNA is made up of repeating subunits called nucleotides . Each DNA molecule consists of 2 long chains of nucleotides. A DNA nucleotide has three parts: a sugar molecule called deoxyribose ; a phosphate group, and a molecule that is referred to as a nitrogenous base because it contains nitrogen atoms. The deoxyribose sugar and the phosphate group are identical in all DNA nucleotides. However, the nitrogenous base may be any one of 4 different kinds. The four nitrogenous bases found in DNA nucleotides are adenine, thymine, cytosine, and guanine. The two strands of a DNA molecule are held together by hydrogen bonds.

These are biology facts.
Answer:
If the disorder has an autosomal recessive inheritance pattern, according to the family tree both parents do not have the disorder, but are carriers.
Explanation:
When a disorder or disease is recessive it requires<u> two alleles with the disorder to manifest</u>. In this case, according to the pedigree, both parents must be heterozygous carriers and not present the disorder.
<u>Parents
</u>
♂ Dd
♀ Dd
Both without disorder but presenting the altered gene, which makes them carriers.
<em>Alleles D d
</em>
<em>D DD Dd
</em>
<em>d Dd dd</em>
The offspring of these parents have a 50% chance of being carriers without the disorder, 25% non-carriers, and 25% with the disorder.
In the event that either parent was DD, there would be a 50% chance of carriers without the disorder and no chance of offspring with the disorder, which has a recessive inheritance pattern.
