1. Which of the below explain how the human genome can be composed of less than 30000 genes and yet we can synthesize over 60000 unique proteins? Explain
a. mutations
b. allosteric regulation of proteins
c. alternative splicing of mRNA
d. Addition of poly-A tails of different lengths
Homework Answers
The answer is coming which is alternative splicing of mRNA. It means that one gene can make different types of mRNA so can makes different types of proteins. It states the one gene many protein theory. But there are several genes which don't code for protein.

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...

In humans, there are about 200 different types of cells. Why are your liver cells different from skin cells, or neurons, or muscle cells? During development, each cell accumulates different mutations changing their DNA They produce the same proteins but some of those proteins are denatured in each cell They have different DNA and thus, each cell produces different proteins They produce the same kind of proteins but not all proteins are active in each cell They have the same...

Genetics Worksheet Week 3: Gene Regulation and Epigenetics 1. Duchenne muscular dystrophy is caused by a mutation in a gene that is 2.5 million nucleotides in length and encodes a protein called dystrophin. The dystrophin protein itself is 3684 amino acids in length. Calculate below the approximate size of the mRNA that encodes dystrophin. Approximately what percentage of the gene that encodes dystrophin is intron sequence? The human genome encodes a much greater variety and number of proteins than the...
