If double stranded DNA has 14% C (cytosine) what percent A (adenine), T(thymine) and G(gaunine) would you expect?

If a double stranded DNA has 20 per cent of cytosine, calculate the percent of adenine in the DNA.

Complete the paragraph Fill in the blanks by selecting the correct word from the bracket and complete the given paragraph. (adenine, phosphoric acid, centromeres, cytosine, nucleotides, ribonucleic acid, guanine, thymine) In 1953, Watson and Crick produced a model of the DNA molecule. As per this model, each strand in the molecule of DNA is made up of many small molecules known as _________. There are four types of nitrogenous bases adenine, guanine, cytosine and thymine_________and __________are called as ‘purines’ while _________and_________ are called ‘pyrimidines’. In the structure of the nucleotide, a molecule of a nitrogenous base and _________are each joined to a molecule of sugar.

Information about protein synthesis is stored in the DNA. Proteins are synthesized by DNA through RNA. This is also known as the central dogma of life. The nucleotide sequences of the mRNA produced are complementary to the DNA strand that is uded as the template for synthesis. This process of synthesis of RNA from DNA is known as transcription. The code for each amino acid consists of three nucleotides (triplet codon) that are present on the mRNA. The tRNA has an anticodon sequence complementary to the cofon on the mRNA. During translation, the code on mRNA is read nad respective amino acids brought by tRNA are joined together by peptide bonds. Based on the given paragraph, answer the followig question: i. If 3'-AACGT-5' is a sequence of the template DNA strand, what would be the nucleotide sequence of the corresponding mRNA synthesized from it? ii. What is the difference in nitrogeneous bases of DNA and RNA? iii. Which enzyme woud be required for the synthesis of RNA from DNA during transcription? iv. How many amino acids can the following mRNA sequence code for ? 5'-UUCAGCCGUGUCAUU-3' v. What is the function of mRNA in translation?

While analysing the DNA of an organism a total number of 5386 nucleotides were found out of which the proportion of different bases were: Adenine = 29%, Guanine = 17%, Cytosine = 32%, Thymine=17%.Considering theChargaff's.rule it can be concluded that:
