The answer is C. 360.

3 nucleotides correspond to 1 amino acid (this is an important fact to remember). Therefore, to create a polypeptide 120 amino acids long, the mRNA "message" would need to be 3 times that length, or 360 nucleotides.

What are the types of gametes​
Vika [28.1K]

In certain organisms, like humans, there are two morphologically distinct types of gametes: (1) the male gamete (i.e. sperm cell) and (2) the female gamete (i.e. ovum). The male gamete is smaller in size and motile whereas the female gamete is several times bigger and non-motile. The haploid condition of the two gametes is essential so that at fertilization during sexual reproduction the integrity of the chromosomal number is maintained throughout generations.

Hope this helps.

Which structure, if transected, will prevent the cerebral hemispheres from communicating with each other?
otez555 [7]
<span>The corpus callosum is what connects the left and right cerebral hemispheres of the brain. If it is severed, it would no longer be able to allow the two sides to communicate. In some cases, it is partially transected (severed) in patients that have severe epilepsy. The procedure is called a corpus callosotomy and is only done as a last resort.</span>
