Question 3 (1 point) Review the animation of the process of transcription. For the following strand of DNA, indicate the sequence of bases on the RNA transcript made from the strand. TTGCATTGAT ab Save Question 4 (1 point) Which of the following occurs in transcription but NOT replication? covalent bonds form between nucleotides to create a long strand of nucleic acid. unwinding the double helix. complementary copies created of both strands of the DNA double helix. production of a single strand of nucleic acid as a product. H-bonds forming between nitrogen-containing basesExplanation / Answer
Answer 3) DNA strand sequence is TTGCATTGAT
In RNA, thymine is replaced by uracil. So, the RNA transcript made from this sequence of DNA strand is AACGUAACUT.
As, thymine (T) base pairs with adenine (A), adenine (A) base pairs with uracil (U). Cytosine base pairs with guanine (G) or vice-versa.
Answer 4) Production of single strand of nucleic acid as a product
In transcription, only one strand of DNA acts as a template for the production of single-stranded primary transcript mRNA.
In replication, each single strand of DNA act as a template to produce a double-stranded DNA.
Answer 5) RNA molecules, newly synthesized proteins
Rifampicin an antibiotic that inhibits the transcription process by binding to the catalytic site of beta-subunit on RNA polymerase. This prevents the elongation of the 5' end of the RNA transcript which is a necessary component for the translation to synthesize new proteins.
Answer 6) a polypeptide strand is made according to directions from an mRNA sequence.
Translation is defined as the conversion of the information contained in mRNA sequence (in the form of codons) into the amino acid sequence. A protein is made up of several polypeptide strands formed by a chain of amino acids.
Replication: a DNA copy is made of the DNA sequence.
Transcription: an RNA copy is made up of a DNA sequence.
