tRNA itself is an RNA molecule with a conserved inverted L structure. One end of the tRNA contains an anticodon loop which pairs with a mRNA specifying a certain amino acid. There is a specific tRNA for each amino acid, 20 in all.
an anticodon loop
Amino acids in the protein
tRNA is attached with amino acid which is called charged. Amino acid attached to the enzyme that is called 3'OH aminoacyl tRNA synthesis. There are different type of tRNA that is specific tRNA around 20.
There is only a 2 tRNA anticodon loop. These loops are very important for the decoding of the mRNA. There are many nucleotides in the anticodon but the third anticodon is very less stringent.
amino acids is the answer in apex
One end of the tRNA matches the genetic code in a three-nucleotide sequence called the anticodon. The anticodon forms three complementary base pairs with a codon in mRNA during protein biosynthesis.
B. Amino Acid
I believe it's C.
cell division is not regulated in tumor cells.
answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.
explanation:carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
