Question
1. Using lecture notes, a textbook, or an online resource, review the structure of a nucleotide, including the two sugars, the 5 bases, the 4 specific DNA nucleotides, the 4 specific RNA nucleotides, the double helix of DNA, complementary base pairing and DNA replication.
2. Define transcription. When does it occur?
3. Define translation, codon, and anti-codon.
4. Describe the 4 levels of protein structure. How does each level depend on the previous level?
5. What cell components required for translation? What is the function of each component?
6. Briefly describe the process of translation from when the mRNA leaves the nucleus.
Explanation / Answer
as per chegg guidelines if you post more than 1 ques , i have to answer oly one ques.
ques 2-- TRANSCRIPTION-- Is the process of conversion of dna into rna (mRNA) by the enzyme RNA polymerase.
it starts when the enzyme RNA polymerase is binded to the promoter site at the beginning of a gene. one of the DNA strands ie the template strand is used by RNA polymerase to make a new,and complementary RNA . the end of transcription is called termination.
it occurs during the INTERPHASE stage of cell cycle.
ques3-- TRANSLATION -- Is a process in which mRNA is converted into proteins in eukaryotes.
CODON -- is a sequence of three nucleotides forming a unit or sequence of genetic code in a DNA or RNA molecule.
ANTICODON -- The anticodon is a region or area of a tRNA which is a sequence of three bases that are complementary to a codon in the mRNA.
