Practice MHT-CET Molecular Basis of Inheritance in the app →DNA was first isolated and named **nuclein** by:Griffith's 1928 transformation experiments used the bacterium:The **Hershey-Chase** experiment (1952) used:DNA replication is best described as:The semiconservative nature of DNA replication was experimentally proved by:A **nucleosome** consists of:**Central dogma** of molecular biology (Crick, 1958) states the flow of information as:The genetic code is a:The **initiation codon** for translation is:Which of the following is **not** a stop codon?In Griffith's transformation experiment, the 'transforming principle' was later identified by Avery, MacLeod aThe **histones** that wrap DNA into nucleosomes are positively charged because they are rich in which amino acDuring DNA replication, the **lagging strand** is synthesised:**Okazaki fragments** on the lagging strand are joined together by the enzyme:**Reverse transcription** (RNA → DNA) is a hallmark of:During **transcription** in eukaryotes, m-RNA is transcribed by:In the structural gene of a transcription unit, the **template strand** has polarity:How many codons in the standard genetic code (a) total exist, (b) are stop codons, (c) code for amino acids?Wobble hypothesis explains:Translation occurs at the **ribosome**. The codon currently being read sits at the:**Introns** in eukaryotic primary transcripts are:In the Meselson-Stahl experiment, *E. coli* grown on ¹⁵N then switched to ¹⁴N gives, after **two** generationsDNA polymerase synthesises new DNA strand in the:Key features of the **genetic code** include all of the following EXCEPT:Cloverleaf t-RNA structure has, at the 3'-acceptor end, the universal sequence:If the anticodon of a tRNA is **3'-UAC-5'**, the corresponding mRNA codon is (read 5'→3'):An insertion or deletion of **one or two** bases in a coding sequence (not a multiple of three) causes:The **30-nm chromatin fibre** in eukaryotic chromosomes arises by:
