Within a strand of RNA, nucleotides can contain one of four different nitrogenous bases. What is the impact of this variation in nitrogenous bases? a
The bases arrange themselves into codons consisting of three bases, with each codon producing a unique amino acid.

b
The different bases code for different amino acids, which build proteins with a wide variety of functions.

c
The nitrogenous bases all form the same types of bonds and, therefore, differ in structure but not chemical properties.

d
The variations in base sequence require a greater number of proteins to carry out RNA translation.

explanation:

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
