Which of the following are the salient features of Human Genome project?
(A) The average gene consists of 3000 bases, but sizes vary greatly.
(B) Chromosome 1 has most genes (2968), and the Y has the fewest (231).
(C) The total number of genes is estimated at 30,000- much lower than previous estimates of 80,000 to 1,40,000 genes.
(D) Repetitive sequences are stretches of DNA sequences that are repeated many times, sometimes hundred to thousand times.

A company purchased a machine for ₹ 15,00,000 and its effective life is estimated to be 10 years. A sinking fund is created for replacing the machine at the end of its effective life when its scrap value is ₹ \(2,42,000\). What amount company should provide at the end of every year out of profits for the sinking fund if it accumulates an interest of \(5 \%\) per annum? [Given: \((1.05)^{10}=1.629\)]

If \(\left|\begin{array}{ccc}1 & \cos \theta & 0 \\ \sin \theta & 1 & \cos \theta \\ \cos \theta & 1 & -\sin \theta\end{array}\right|=A \sin \theta+B \cos \theta+C \sin \theta \cos \theta\) then :

Which one of the following statement is incorrect about sinking fund?

Read the passage carefully and answer the given questions. DNA Fingerprinting
Polymorphism in DNA sequence is the basis of genetic mapping of the human genome as well as of DNA fingerprinting. DNA fingerprinting involves identification of differences in some specific regions in the DNA sequence called repetitive DNA. It works on the principle of polymorphisms in DNA sequences. The repetitive DNA are separated from bulk genomic DNA. The bulk DNA forms a major peak and the other small peaks are referred to as satellite DNA. These repetitive/satellite DNA sequences show a high degree of polymorphisms and form the basis of DNA fingerprinting.
