What are the differences between miRNA and siRNA? (Select all that apply.) OmiRNAs carry the genetic information from the DNA in the nucleus directly to the cytoplasm, and siRNAs are involved in the degradation of specific mRNA molecules. miRNAs are from 22 to 30 bases long, and siRNAs are 22 bases long. O miRNAs carry the genetic information from the DNA in the nucleus directly to the cytoplasm, and siRNAs help with the processing of the initial mRNA transcribed from DNA into a mature form. miRNAs prevent translation of certain mRNAs, and siRNAs are involved in the degradation of specific mRNA molecules. miRNAs are 20 to 22 bases long, and siRNAs are from 20 to 30 bases long.
A. The diagram below shows a tRNA molecule. (i) Which part of a cell is the tRNA produced? (ii) Which part of this tRNA molecule (X, Y, Z) is amino acid attached to? Is ATP or GTP required in the formation of this attachment? (iii) Which part of this tRNA molecule (X, Y, Z) binds to mRNA? Name the bond formed at this part of tRNA with mRNA. (iv) Write the sequence of consecutive Z and amino acid sequence corresponding to the following mRNA sequence. 3' AUGCCGUACUAG 5' In your answer, copy the mRNA sequence. Below the mRNA sequence, write the TRNA sequence with 5' & 3' labels (from left to right), AND the amino acid sequence.

A scientist mutates elF-2 to eliminate its GTP hydrolysis capability. How would this mutated form of elF-2 alter translation? Initiation factors would not be able to bind to mRNA The large ribosomal subunit would not be able to interact with itiRNA transcripts tRNAi-Met would not scan mRNA transcripts for the start codon elF-2 would not be able to interact with the small ribosomal subunit.
Can you explain it?
2a) In prokaryotes, a small ribosomal subunit can potentially get on an mRNA anywhere it can find enough space to do so. Once a small ribosomal subunit has bound to an mRNA, it will scan along that mRNA in the 5' to 3' direction looking for a start codon at which to initiate translation. How does the small ribosomal subunit distinguish a start codon from any other AUG codon that simply codes for methionine in the middle of a coding sequence?
Can you help me with this question?
