Question

True or False:

1. In an individual human, the pattern of gene expression is identical across all different types of somatic cells

2. The stem cell potential of a fertilized human egg is pluripotent

3. In an individual human, different types of somatic cells have the same genome.

Answer 1

1) n an individual human, the pattern of gene expression is identical across all different types of somatic cells -FALSE

In an human individual the somatic cell contain the same set of genome (diploid) .But the expression of the genes in the somatic cell will be different.Somatic cells are specialized to do various type of functions in our body

a cell defferienciated to do a particular function is with the help of proteins molecules in the cell. This protein molecules are prooduced by the translation of the expressing gene in the somatic cell.

2) The stem cell potential of a fertilized human egg is pluripotent -TRUE

Fertilized human egg are pluripotent cell because it can generate any type of cell in th body.The fertlized egg will eventually attach to the endometrium of the uterus with the help of trophoblast. inner cell mass of the embryo will develop in to 3 germ layer. they are ectoderm,mesoderm and endoderm.

These germ layer give rise all the type of cell in the body.

3) In an individual human, different types of somatic cells have the same genome -TRUE

Genome are the set of chromosomes in the cell

all the somatic cell in our body contain same genome

somatic cell is diploid cell with 2 set of haploid number of chromosome.

A single human genome (haploid) contain 3 billion basepairs.
