Answer #1

The DNA sequences which are not transcribed but are essential are called Non-coding DNA. It varies in amount in different organisms (about 99% of total DNA in many organisms). They do not provide instructions for making proteins, but they are involved in many functions of cells like controlling genes' activities, transcribing non-coding RNAs like transfer RNA (tRNA), ribosomal RNA (rRNA), etc. They provide sites for transcription factors (specialized proteins) which activate or repress genes' activities. They contain many regulatory elements like promoters, enhancers, silencers and insulators. These DNA sequences are not junk but very essential for cell functioning.

    Below are several DNA sequences that are mutated compared with the wild-type sequence: 3-TAC TGACTGACGAT C-5. Envision that each is a section of a DNA molecule that has separated in preparation for transcription, so you are only seeing the template strand. Construct the complementary DNA sequences (indicating 5' and 3' ends) for each mutated DNA sequence, then transcribe (indicating 5' and 3' ends) the template strands, and translate the mRNA molecules using the genetic code, recording the resulting amino acid...

  • The transcribed portion of a DNA sequence for a gene is shown below

    The transcribed portion of a DNA sequence for a gene is shown below. Identify the mRNA sequence and the polypeptide sequence that would be produced from this gene. Also, identify the specific type of DNA mutation and protein mutation that would result if the underlined A/T basepair was mutated to a C/G basepair. NOTE: Assume RNA polymerase is moving left to right across the page. 3' - TATACGCGATATGGATTC - 5 5'- ATATGCGCTATACCTAAG - 3

    Sequence motifs are the sequences of nucleotides that indicate what types of function or absence of function may be encoded in a particular region of the genome. Which statement is true regarding sequence motifs? Sequence motifs are found in DNA and in corresponding RNA produced by transcription. Sequence motifs are telltale sequences of nucleotides that indicate possible function. An open reading frame (ORF) is a type of sequence motif. Sequence motifs help identify sequences that encode protein-coding genes. All of...
