Genetics

AnsB. accumulates new mutations at higher rate. The function of deoxyribonucleic acid polymerases is puzzle out in new fundaments in the 3’ supplant sothat the synthesis of desoxyribonucleic acid chain grows in 5’ to 3’ direction. and desoxyribonucleic acid polymerases can also degrade nucleic acids and are called nucleases. Those that stick by from the end are called exonucleases. During replication those nucleotides that are in malign positions should be removed from the exonuclease activity before the next nucleotide is added. This is called proofreading and protects the DNA from mismatches and if it does not function properly more errors or mutations occur. indeed the gene makes due to the failure of the in a higher place activity. 7.Ans. C. the answer is 1/9. There are 1/9 remainders of aminoacids is synthesized from this copolymer is Phenyl alanine. Phenylalanine is re surrendered as UUC or UUU. For the UUU at that place is 1/31/31/3= 1/ 27. Fro the UUC codon of this very(prenominal) aminoacid (Phe) there is a ratio of 1/31/32/3=2/27. So for the devil proportions (the sum of the two proportions ) is the phenylalanine ratio from the copolymer. Therefore. 1/27+2/27=3/27=1/9 and this 1/9 is the proportion of Phenylalanine. 9.Ans.D. There are 72 distinguishable seasons ofDNA are present for the protein sequence of Met-Arg-Trp-Phe-Ser.

According to the genetic work out virtually amino acid has more than one musical musical mode of sequences derived from the different sequences of template RNA and thus different sequences of DNA. Accordingly almost aminoacids exhaust 2 ship canal of m! RNA codons representation. Phnylalaline has 2 ways of codons which are UUC and UUU. And other aminoacids from the genetic table grow 6ways which we go the reading of mRNA from the table. Therefore for the above sequence we have 16126=72 ways of writing the protein. The sequence was Met-Arg-Trp-Phe-Ser and worry the above calculation for each one way of mRNA codon is multiplied to each other and we express 72 ways. 15kb _ 14kb _ 9kb _ 4kb 5kb+2kb +6kb +2kb= 15kb. This is how we get the sum of kbs for the...If you inadequacy to get a full essay, orderliness it on our website: BestEssayCheap.com
