Answer:

C. a stop codon is reached.

Explanation:

Translation is the process by which proteins are synthesised from mRNA. It ends in the termination stage when a stop codon is encountered. Normally during translation the A-site of ribosome is responsible for binding the complementary codon on the mRNA with the incoming tRNA. The tRNA with the polypeptide chain is hold by the P-site.

During termination, a stop codon ( UAA, UGA or UAG) is encountered by the A site in ribosome and is then recognised by release factors. Release factors enter the P site and fit there leading to disassembly of entire ribosome/mRNA complex. A water molecule is added to the last amino acid of the chain which separates it from the tRNA molecule and leads to its release.

Alleles are alternative form of gene and are present at same place on chromosome
suppose the two alleles S and T are controlling leaf colour so the genotype that will b possible is SS.ST.TT and for species B the 6 phenotypes will occur so i conclude that

What are the helpful measures to conserve human energy??​
GarryVolchara [31]

Answer:

Adjust your day-to-day behaviors

Energy conservation can be as simple as turning off lights or appliances when you do not need them. You can also use energy-intensive appliances less by performing household tasks manually, such as hang-drying your clothes instead of putting them in the dryer, or washing dishes by hand.

DNA is replicated in the nucleus of eukaryotes, but in the cytoplasm of prokaryotes. Why is this?
umka2103 [35]

Answer:

In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All three processes can occur simultaneously.

   In eukaryotes (organisms with a nuclear membrane), DNA undergoes replication and transcription in the nucleus, and proteins are made in the cytoplasm. RNA must therefore travel across the nuclear membrane before it undergoes translation. This means that  transcription and translation are physically separated. The primary transcript, heterogeneous nuclear RNA (hnRNA), undergoes extensive post-transcriptional processing to make a messenger RNA (mRNA)molecule that can pass through the nuclear membrane.
