The DNA STRAND IS 3’ TAC-AGC-ACT-CAG-TCA 5’ and Non-template strand = 5' - ATG-TCG-TGA-GTC-AGT - 3' . If on the non-coding strand of DNA there is suddenly one T base that sneaks into the 4th sequence (from the left), or causes a mutation, then how will the RNA be formed and the chain arrangement of the amino acids produced by this mutation? 4th sequence (from the left) should be = TCG right?
Which of the following is true regarding the 5’ vs. the 3’ end of a strand of DNA? a) only double-stranded DNA can have a 5' and a 3' end b) 5' and 3' are designations of the carbon in the deoxyribose of a nucleotide that is not bound to another deoxyribose or phosphate group c) 5' and 3' are designations of the DNA base that is unbound to another base d) The 5' end of DNA is always considered the start of the gene and the 3' end is considered the end

DNA is made of two strands that are antiparallel. If one strand runs from 3’ to 5’ direction the other one will go from 5’ to 3’ direction. During replication or transcription, whatever the process is, it will always follow the 5’ to 3’ direction using the 3’ to 5’ directed strand as the template strand. Therefore, if following is the DNA sequence5’-CCG ATC GCA CAA-3’a) Using this sequence as template after transcription no protein can be translated. Why? I. Presence of start codonII. Absence of start codonIII. Due to mutationb) If you want to start the translation, what change you need in the second codon (from 5’ to 3’ direction)?I. Substitution of C with GII. No changeIII. Deletion of CIV. Both I & III
