Question 4 Two ends of a tRNA molecule are important. Why? one end attaches to the ribosome and the other end attaches to the DNA, or one end is the anti-codon and the other end attaches to the introns, or one end is the codon and the other end is the anti-codon, or one end attaches to an amino acid and the other end is the anti-codon
Homework Answers
Answer
Two ends of the tRNA molecule are important because
One end is the anti-codon which base pair with the codon on the mRNA. While the other end carries covalently attached amino acid corresponding to the anti-codon.
I hope this will help you if you like it then give me a thumbs up, thank you!

Please explain
Why is a cap added to MRNA, but not to 1RNA or RRNA? Each of the three types of RNA are transcribed by different RNA polymerases. Only RNA polymerase II, involved in mRNA synthesis, contains a domain capable of interacting with enzymes that form the cap. Transcription and processing of MRNA occur in the nucleus, where cap binding proteins are found. These proteins, which add and modify the cap, are not found in the cytoplasm, where tRNA and...

Which is the most inappropriate description of matured tRNA? Select one: a. 3’-end always has the CCA sequence. b. tRNA has many covalent modifications. c. Cells must carry all ~61 different tRNA to decode all possible codons in mRNA. d. Amino acid is loaded to 3’-end of tRNA. e. Amino acyl tRNA synthase for tRNATrp is specific for both Trp and the Trp anti-codon in tRNA.

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...

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...
