Question

Molecular basic of inheritance
1 point DNA:- ​

Answer 1

Answer:

I think it's your answer

Step-by-step explanation:

DNA is the genetic material in most of the organisms except some viruses, which have an RNA genome, e.g. TMV (Tobacco mosaic virus)

RNA mostly acts as a messenger, an adapter and has a catalytic function

Number of base pairs (bp) or nucleotides determines the length of the DNA

Human DNA (haploid) – 3.3 x 109 bp

Bacteriophage x 174 – 5386 nucleotides

Bacteriophage – 48502 bp

E. coli – 4.6 x 106 bp

Friedrich Meischer in 1869 identified DNA present in the nucleus as an acidic substance and named it as ‘Nuclein’

Frederick Griffith in 1928 demonstrated in the infected mice that some “transforming principle” gets transferred from heat-killed S-strain of Streptococcus pneumoniae to R-strain, enabling it to make the smooth polysaccharide coat, hence it becomes virulent

Oswald Avery, Colin MacLeod and Maclyn McCarty determined the biochemical nature of “transforming principle” and discovered that only DNA is responsible for the transformation

Hershey and Chase in 1952 proved that DNA is the genetic material. They infected the bacteria E. coli with bacteriophages grown in radioactive phosphorus (32P) which labels DNA of the bacteriophage, which gets transferred to the bacteria cells and radioactive sulfur (35S), which labels the protein coat of the bacteriophage, hence radioactivity is not detected in the bacterial cell

Answer 2

Answer:

RNA

Ribonucleic acid or RNA is a vital molecule with a long chain of nucleotides. It is the first genetic material. A nucleotide chain comprises a phosphate, a ribose sugar, and nitrogenous base. RNA acts as a catalyst and as genetic material. There are two types of RNA, that is genetic and non-genetic.

Genetic Code

The genetic code can be defined as a set of rules wherein the information encoded in genetic materials are translated into proteins by living cells. The code defines how codons specify which amino acids will be added next during protein synthesis.

The frequency of codon is termed as codon usage bias. It varies from species to species in terms of functional implications for the control of translation.

The genetic code can also be defined as a relationship between the sequence of amino acids in a nucleotide chain of mRNA or DNA and amino acid in a polypeptide chain.

Nearly twenty types of amino acids participate in protein synthesis. Sixty-one codons out of sixty-four codons code only for amino acids. The characteristics of the genetic code are stated below:

Degeneracy of genetic code.

Non-overlapping.

Universality.

Triplet in nature.

Comma-less.

Non-ambiguous.
