Question

(b)Where in the cell does this process occur? Q3 to create a protein. is the process in which mRNA is used as a template (b)Where in the cell does this process occur? Q4 carries amino acids to the ribosome for protein synthesis. Q5 Give the complementary DNA sequence to AGGCTATTCATT. Q6 Give the complementary RNA sequence to AGGCTATTCATT. Q7 Use Table 9.4 to give the amino acid sequence that results from the above RNA. Q8 What are two differences betweeen the structure of RNA and DNA nucleotides? Q9 Describe the overall structure of DNA. D. Focus

Answer 1

3) TRANSLATION

Translation is a process in molecular biology where genetic code contained within an mRNA molecule is decoded to produce the specific sequence of protein in the ribosomes present in cytoplasm or ER.

This process occur in the ribosomes of the cell, which is either free in cytoplasm or attached to the Rough endoplasmic reticulum.

4) tRNA/ Transfer RNA

tRNA is a single stranded RNA that transfers the required amino acids to the ribosome during the process of translation. This RNA has a clover leaf shape, or L-form in 3D orientation. It has an anticodon group which binds to the corresponding codon on the mRNA and helps in transfering the corresponding amino acid during protein synthesis.

5) The complementary sequence for a DNA strand can be obtained by replacing:

1. A $\rightleftharpoons$ T
2. C $\rightleftharpoons$ G

So the sequence will be:

5' TCC GAT AAG TAA 3'

6) The only difference between complementary ​​​​DNA and RNA is that we replace A $\rightleftharpoons$ U

So the sequence for RNA would be:

5' UCC GAU AAG UAA 3'

It was a pleasure answering your questions. Hope this helps...

Good luck!!
