Below is the 5'-3' strand of a double-stranded DNA molecule with the following nucleotide sequences: 5' CCTATGCAGTGGCCATATTCCAAAGCATAGC 3' 1. If the above DNA strand is the coding (sense) strand and the DNA molecule is transcribed, what is the correct nucleotide sequence and direction of the RNA formed after transcription? 2. If the RNA synthesized above (item #1) is a functional mRNA and all the nucleotides belong to an exon, a. how many codons are present in this mRNA? b. how many codons actually code for proteins in this mRNA? c. what stop codon is present in this mRNA? 3. If the above DNA strand is the template (antisense) strand and the DNA molecule is transcribed, what is the correct nucleotide sequence and direction of the RNA formed after transcription? 4. If the RNA synthesized above (item #3) is a functional mRNA and all the nucleotides belong to an exon, a. how many codons are present in this mRNA? b. how many codons actually code for a protein in this mRNA? c. what stop codon is present in this mRNA?
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
