Explanation / Answer

The diploid number of chromosomes in humans is 46. The haploid number is _________.
The answer is 23. As haploid contians half of the diploid chromosomes, the haplid number is 23.

The bases of RNA are the same as those of DNA with the exception that RNA contains:
The answer is uracil instead of thymine.

Uracil is present in RNA where as Thymine is present in DNA.

DNA nucleotides are read in clusters of:
The answer is 2.

Because Adeine pairs with thymine with two hydrogen bonds and Guanine pairs with Cytosine with three hydrogen bonds.

Messenger RNA (mRNA) has a three-nucleotide sequence called a(n) __________________, while the molecule transporting the amino acid (tRNA) has a complementary sequence called a(n)

The answer is codon; anticodon
