3 Shows high degree of polymorphism in population and also the same degree of polymorphism in an individual, which is heritable from parents to children
4 Does not code for proteins and is same in all members of the population
Explanation:
Satellite DNA is important because it shows high degree of polymorphism in population and also the same degree of polymorphism in an individual, which is heritable from parents to children. The name satellite DNA refers to the phenomenon that repetitions of a short DNA sequence tend to produce a different frequency of the bases adenine, cytosine guanine and thymine.

In a DNA segment having six coils, there are 22 nitrogen base pairs linked by two hydrogen bonds. How many cytosine bases are found in that segment
1 22
2 38
3 44
4 76
Explanation:
DNA has 4 bases, 2 purines and 2 pyrimidines. Purines are namely \(A\) and \(G\) and the pyrimidines are \(\mathrm{C}\) and \(\mathrm{T}\). One complete turn of the double helix has 10 base pairs. Therefore, 6 coils of DNA will have \(10 \times 6=60 \mathrm{bp}\). A and T bases form 2 hydrogen bonds. Thus, the total number of \(\mathrm{C}\) and \(\mathrm{G}\) base pairs is \(60-22=38\). As the number of \(\mathrm{C}\) bases is equal to the number of \(\mathrm{G}\) bases, both equal to 38 bases.

X-rays are used in
1 ECG
2 EEG
3 CT-scan
4 Endoscopy
Explanation:
X-rays are used in CT-scan (computed tomographic scanning). X-ray use invisible electromagnetic energy beams to produce image of internal tissues, bones and organs on film or digital media. Standard X-ray performed for many reasons, including diagnosing tumors or bone injuries. X-ray used in CT-scan and fluoroscopy.

Explanation:
In cells, DNA (Deoxyribonucleic acid) is the nucleic acid that functions as the original blueprint for the synthesis of proteins. DNA is a double-stranded molecule that has a long chain of nucleotides. DNA replicates on its own. It is self-replicating. RNA (Ribonucleic acid) is a single stranded molecule which has a shorter chain of nucleotides. RNA does not replicate on its own. It is synthesized from DNA when required. - DNA and RNA both can function as genetic material. - DNA is storage of genetic material and RNA transfers genetic information.
