The Human Genome Project showed that human DNA is not considerably bigger than much simpler organisms, with about 30,000 total genes. However, humans make over 100, 000 different proteins. How is this possible? (Hint: think about splicing.)

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?
Once translated into proteins: (a) How many nucleotides are there? (b) How many codons are there? (c) How many amino acids?
Geneticists have found that when they cut out a eukaryotic gene from genomic DNA that they can hybridize one of the strands of that gene to the mRNA for that gene by allowing the strands to hydrogen bond. Why is it sometimes claimed that alternative splicing of exons from a single gene results in a set of proteins of related function?
a molecular geneticist hopes to find a gene in human liver cells that codes for an important blood-clotting protein. he knows that the nucleotide sequence of a small part of the gene is gtggactgaca. briefly explain how to obtain the desired gene answer
What is the genetic code? Explain!
If the coding region of a gene (the exons) contains 2,100 base pairs of DNA, would a missense mutation causes a protein to be shorter, longer, or the same length as the normal 700 amino acid proteins? What would be the effect of a nonsense mutation? A sense mutation?
The human genome has 3.3 billion bases, of which 3% codes for protein. If a codon were four letters instead of three, what percentage of the genome would have to code to generate the amount of protein?
Suppose you are provided with a sequence of nucleotides. How would you determine if the sequence is of mRNA, tRNA, or DNA molecules?
Consider a portion of a gene in a cell with the sequence TTTTT. Which of the following bases would you find in the complementary RNA strand, and where in the (eukaryotic) cell would this RNA be synthesized? A) A-A-A-A-A; ribosome B) U-U-U-U-U; ribosome C) A-A-A-A-A; nucleus D) U-U-U-U-U; nucleus
How many nucleotides would be carried on a strip of mRNA with 10 codons?
What might be the result of a mutation of DNA in which a triplet code such as UAC now says UAA in the middle of a protein? Could this cause problems? Might we see these problems in nature? Speculate as to an
Which of the following describe how the order of nucleotide bases along a gene in the DNA ultimately determines the primary structure of a protein and how the primary structure ultimately determines the three-dimensional shape and function of the protein coded for by that gene. A Certain amino acids in a protein interact with other amino acids in that same protein and so the order of amino acids ultimately determines the 3-dimensional tertiary structure of that protein. B The order of nucleotide bases along the DNA is transcribed into complementary tRNA which is translated into the correct amino acid sequence for the protein by mRNA. C The order of nucleotide bases along a gene determines the order of amino acids in the resulting protein. The order of amino acids in the protein is called its secondary structure.
