- Eukaryotic mRNA: usessnRNPs to cut out introns and seal together translatableexons. uses a spliceosome mechanism made of DNA to recognizeconsensus sequences to cut and splice. has a guanine cap on its 39 end and a poly(A) tail on its 59 end. is composed of adenine, thymine, guanine, and cytosine. codes the guanine cap and poly(A) tail from the DNAtemplate.When the human genome sequence was finally completed, scientists were surprised to discover that the genome contains far fewer genes than expected. How many genes are present in the human genome? Scientists have also found that there are many more different kinds of proteins in human cells than there are different genes in the genome. How can this be explained?8) Which of the following best describes why it is possible for the bacteria to read the instructions in a human gene and produce a human protein as a result? Bacterial cells and human cells are identical and contain the same organelles Bacterial cells and human cells both use DNA to store their genetic information The genetic code is universal - the same codon codes for the same amino acid in all species The bacterial cell already contains a gene that is very similar to the human growth hormone gene
- Milk is secreted by the cells of the mammary glands. Casein is the main protein found in milk. It is coded by a gene ofa known sequence of nucleotide. In some human females, their mammary glands secrete non functional casein. The following document presents a part of the transcribed gene that codes for functional and nonfunctional casein. Codon number Nucleotide Sequence 1 TAC ТАС 3 4 CTT CTT TTG TTG СТС AAT Functional casein Nonfunctional casein TTC AAT TTC CTC AAT АTT Document 2 4- Write using the genetic code table, the amino acids sequence of the two types of casein proteins coded by the above nucleotide sequence. 5-1-Compare the nucleotide sequence coding for the 2 types of casein protein and the amino acids sequence coded by these nucleotide sequences. 5-2-Draw out the origin of producing non-functional protein.Protein synthesis is a complicated process involving DNA being transcribed to RNA, which is then translated into amino acids. Complete the DNA-to-amino acid table for three consecutive codons with the appropriate nucleotides and amino acids using a codon table. Nucleotide and amino acid options can be used multiple times or not at all. 5' to 3' DNA strand 3' to 5' DNA strand transcribed mRNA tRNA anticodon amino acid arginine cysteine leucine T A U A T G A U arginine leucine A proline T A U Answer Bank A G G с с T T A A U glutamic acid U G C G с с glutamic acid G G G с с G C arginine C G с GA Section of a GeneAAG ATA CAG GCT CGG TAA For the DNA sequence shown above, identify the following: mRNA codons tRNA anticodons amino acids The section of a gene shown above (AAG ATA CAG GCT CGG TAA) is called the Answer (template or non-template) strand.
