The normal human karyotypes contain 22 pairs of autosomal chromosomes and one pair of sex chromosomes.
Therefore the best answer choice is:
<span>B. 1 pair of sex chromosomes and 22 pairs of autosomal chromosomes are pictured.
</span>A karyotype is an organized profile of a person's chromosomes. Two chromosomes specify sex, XX for female and XY for male. The rest are arranged in<span> pairs, numbered 1 through 22, from largest to smallest.</span>
Answer:
A., Vision. Eyes contain two types of photoreceptors called rods and cones.
Answer:
Option (1).
Explanation:
The RNA is produced from the DNA by the process known as translation. The proteins products are produced from the RNA by the process known as translation. Proteins are the polymers of the amino acids.
The situation 1, radioactive amino acids has been used. In this case, the mRNA is used in this process to make the radioactive proteins by the process of translation. The radioactive amino acids are used for the formation of radioactive protein. The situation 2, the RNAase has used with radioactive amino acids. In this case, the RNAse enzyme breaks the mRNA molecule and the proteins are not translated that contains the radioactive amino acids. No proteins formation occurs in this case.
Thus, the correct answer is option (1).
