How are the base-pairing rules different for RNA than DNA?
In RNA, Guanine is replaced with Uracil
In RNA, Cytosine is replaced with Uracil.
In RNA, Adenine is replaced with Uracil.
In RNA, Thymine is replaced with Uracil.
How can embryonic stem cells differentiate into many different cell types?
The regulation of gene expression is within each cell type.
The regulation of the cell type is controlled by the nervous system of the organism.
The regulation of the gene expression is set at the birth of the cell.
The cell type and gene expression is predetermined.
What is the role of tRNA in protein synthesis?
tRNA carries the amino acids to the ribosome for protein synthesis.
