in DNA, the Us in RNA are originally As
the answer is ttg atg acg
The correct answer is-
The original DNA base sequence is- TGG ATG ACG.
Transcription is a process of formation of mRNA ( messenger RNA) from DNA ( deoxyribonucleic acid) that is transfer of genetic information from DNA to mRNA.
During this process, one strand of DNA acts as template, using which enzyme RNA polymerase synthesizes mRNA, which is complementary to the template DNA. The bases in the mRNA are added in the following manner-
For Adenine, Thymine, Cytosine, and Guanine in the template DNA, bases Uracil, Adenine, Guanine, and Cytosine respectively are added in the mRNA transcript by the enzyme RNA polymerase.
Therefore, for the given mRNA sequence ACC UAC UGC, we can deduce the original DNA base sequence, that is TGG ATG ACG.
Codon may defined as a sequence or code made up of three nucleotide bases. There are total 64 codons, made up from different combinations of nucleic acid bases (A, G, C, T). Each codon codes for a specific amino acid. The amino acid coded by GUU codon is valine and amino acid coded by AAA codon is lysine.
Thus, the correct answer is option 'A). valine-lysine.'
the right answer is c. ttg atg acg
The genes carried by the DNA will be encoded in another form: messenger RNA, during a process called "transcription".
The information contained in the genes will be used to make thousands of proteins involved in the functioning of the cell. The first step in the expression of a gene is to copy its information in the form of a molecule very close to DNA, ribonucleic acid or RNA.
The main difference between DNA and RNA is the presence of an extra oxygen atom on each of the nucleotides of the RNA. This addition provides greater flexibility to the RNA, allowing it to fold on itself to form propellers. Due to its structural properties, RNA takes a wide variety of forms and ensures a variety of roles in the cell. DNA, on the other hand, is more static and stable, and its essential function is the storage of information in the form of a double-stranded helix. Another change: in RNA, thymine (T) is replaced by uracil (U).
In the transcrption of DNA, the strand of the RNA formed is complementary to that of the DNA:
* A is matched to the U
* T is matched to A
* C is paired with the G
* G is paired with C
TTG ATG ACG
The A codon (adenine) would translate back to T if you are going back to the original sequence. The U would translate back to A.
