1. An individual with classic symptoms of Down syndrome is found to have 46 chromosomes. How can this be?

		This is possible if the individual has an extra chromosome 21 but has only one copy of chromosome 1.
		This is not possible.
		It is possible if she or he carries a chromosome translocation, such as 14/21.
		It is possible if she or he carries a chromosome inversion.

The area on a tRNA molecule which connects to a specific mRNA molecule is called

		an anticodon.
		a start codon.
		a peptide.
		complement.
		DNA.

1. Answer 2. This is not possible. Explanation: Down Syndrome is the Congenital disease in which there is trisomy of 21st Chromosome. Therefore, There is total 47 choromosome. Weorg option : 1. Extra 21 chromosome but there is no copy of 1 chromosome. 2. There is no chromosome translocation. 4. There is no chromosome inversion. Q2. Answer 31. Anticodon - Explanation Anticodon is triplet of bases present on t RNA that is complemetary to the codes bases present on mRNA which MERRNA connected by Hydrogen bondo E-RIJA O Antiesdon Wrong option 2. start codon : It is present on mRNA, 3. Peptide : It is long chain amino acid. GOD 4. complement DNA = DNA has no role in this process.
