Question 2: Transcription, RNA Processing and Translation A particular gene codes for a mature mRNA transcript containing 1200 bases, which is translated into a protein containing 300 amino acids. A. How long is the coding sequence in this mRNA and how many nucleotides are in the UTRs? For the purposes of this question we are ignoring the G’ cap and the polyA tail. B. A mutant form of the gene created by one nucleotide being changed to another nucleotide also...

would the first one be D and the second one C?
"The processing of some tRNA molecules, like that of most mRNA molecules, involves the addition of a poly-A tail at their 3' end the addition of a poly-A tail at their 5' end the addition of a CCA sequence at their 5' end the addition of a CCA sequence at their 3'end the alternative deletion of random segments splicing "In general, are the longest RNAs produced in eukaryotic cells"...

a piece of eukaryotic DNA is shown below: 5’- CACTCACCCGATTTTTGAATGCCGCTGATGAATCTCTGGTAA -3’ A) WHAT IS THE mRNA PRODCUED, IF THIS IS THE CODING STRAND? b)Assuming that after processing, a cap is added to the mRNA at the 5’ end, predict the amino-acid sequence of the protein produced from this piece of mRNA using SINGLE LETTER codes. In your answer denote both the amino and carboxy ends of the protein? THANKS FOR THE HELP.

Question 8 (1 point) The primary RNA transcript of the chicken ovalbumin gene is 7700 nucleotides long, but the mature mRNA that is translated on the ribosome is 1872 nucleotides long. This size difference occurs primarily as a result of: O addition of the poly A tail O removal of exons O splicing O addition of the 5' cap Question 7 (1 point) Which of the following recognizes the promoter region of a gene in E. coli allowing RNA polymerase...
