The human genome contains about 20,000 genes, but the human body can generate over 100,000 different proteins. How is it possible that humans have so few genes but can generate so many proteins?
A. Humans likely have over 100,000 genes, but many have yet to be identified
B. mRNAs of different genes can recombine to generate many different proteins
C. the majority of proteins found within a cell are acquired from the environment
D. mutations in DNA generate many versions of each protein
E. alternative splicing of mRNAs produced from one gene generates different proteins
Homework Answers
The correct answer according to me is:
Option E) alternative splicing of mRNAs produced from one gene generates different proteins

In humans, there are about 200 different types of cells. Why are your liver cells different from skin cells, or neurons, or muscle cells?

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.

The human immune system can generate approximately 105 different heavy chains and approximately 103 light chains. Any light chain can pair with any heavy chain, so there are 108 different antibodies that are possible. Camels lack light chains but have approximately the same level of diversity, about 107 different antibodies. How do you think their heavy chain gene differs from humans?

three part question!!!!
Lab Activity for RNA Processing: p53 Isoforms Isoforms, simply defined, are different proteins created from the same genomic sequence. These differences can be created by a variety of mechanisms, including alternative splicing, the usage of different promoters, and the usage of different start codons. The p53 gene (usually called Tp53) is located on the short arm of chromosome 17 in the human genome. It has some unique gene topography, including one non-coding exon and very long intron...
