During elongation of proteins during protein synthesis tRNA with the amino acid that matches its anticodon binds to the codon on the mRNA. each new amino acid is first transferred to the anticodon of the tRNA. anticodons on the ribosomes recognize the codons on the mRNA and attach the correct amino acids. ribosomes move along the DNA. RNA polymerase II uses the codons on the mRNA to polymerize the protein.

Complete a concept map of translation, indicate where it takes place, and describe what will happen if the anticodon is not attached to transfer RNA. A)DNA unzips ?transcription of mRNA ? mRNA leaves nucleus ? mRNA binds to ?ribosome ? tRNA brings in amino acid? tRNA anticodon binds to codon on mRNA ? peptide bond binds amino acids to form protein ? transport of the amino acids to the mRNA by tRNA continues until the mRNA translation is completed. This...

The three letter "code words of DNA and RNA that specify amino acids are called: A. codons B. promoters C. Introns D. anticodons 20. Proteins are composed of building blocks called: A. fatty...
There are 20 different tRNA molecules, one for each of the 20 amino acids found in protein. During protein synthesis, the job of a tRNA molecule is to carry its particular amino acid to the growing protein chain and find the correct amino acid position there. It does this by matching a 3- letter anticodon on the tRNA to a complementary 3-letter codon on mRNA. Below, in a diagram of a ERNA molecule, nucleotides are represented by small circles, some...
Q1 Arrange the following steps of protein synthesis in the correct order (Number in the correct order). mRNA is generated. DNA unwinds to become single stranded. mRNA binds to a ribosome. Ribosome links amino acids together. RNA anticodon basepairs with mRNA codon. mRNA is transported out of the nucleus. protein is complete! Q2 (a)_______ is the process in which DNA is used as a template to create RNA. (b)Where in the cell does this process occur? Q3_______ is the process in which mRNA is used as a template to create a protein. (b)Where...

RNA differs from DNA in that it uses: Group of answer choices uracil instead of thymine. uracil instead of guanine. guanine instead of uracil. uracil instead of adenine.
In protein biosynthesis Question options: A. each amino acid recognizes its codon on the mRNA template because of structural specificity. B. exactness of read-out is assured by the presence of traces of DNA on the ribosome. C. each amino acid is first attached to tRNA that has an anticodon specific for the amino acid. D. a given codon-anticodon pair must have identical base sequences to avoid the formation of degenerate proteins. E. each amino acid recognizes its codon through recognition...
Question 9:
The genetic code is read in groups of three nucleotides, called
codons, in mRNA that specifies for a particular amino acid.
tRNA molecules act as the amino acid carriers that by correctly
pairing with the codon on mRNA can deliver the correct amino acid
to the ribosome during translation. At the tip of each tRNA
molecule is a group of three nucleotides called an anticodon and at
the other end is where the corresponding amino acid is attached...
QUESTION 7 If the MC1R protein is 317 amino acids long why are there 954 base pairs in the coding region of the gene? Each amino acid has a mRNA codon and DNA triplet consisting of a three-base sequence. (317 x 3951 plus a stop codon (951-3-954) to signal the end of translation) Because there are 317 proteins in the MC1R code. mutant proteins always have 954 base pairs. Each amino acid has a mRNA codon and DNA triplet consisting...
