Ans.
Albinism shows a genetic disorder, which is characterized by absence of coloration or pigmentation in individuals. It is an autosomal recessive disorder that transmits from parents to their offspring, when offspring receives both the mutated copies of gene responsible for albinism.
For a genetic disorder, dominant or wild type allele is represented by capital letter, such as 'A', while recessive or mutated allele is represented by small letter, 'a'. As 4th picture is representing male and female gametes with recessive alleles (a) , the resulting zygote will have both recessive alleles for albinism (aa), '4th zygote will develop into an albino child.'
Answer:
If the sequence of one strand on DNA is CTA GCT CCA, the
complementary strand is GAT CGA GGT.
Explanation:
The DNA molecule has four nitrogenous bases in its structure, two purines —adenine and guanine— and two pyrimidines, cytosine and thymine.
The two DNA strands are linked by hydrogen bonds established between their complementary nitrogenous bases, where a purine is complemented by a pyrimidine.
In the case of DNA, adenine is complemented by thymine and cytosine is complemented by guanine:
<em>A=T</em>
<em>C≡G</em>
In the sequence belonging to a DNA strand CTA GCT CCA, the strand that is complementary would be GAT CGA GGT.
