Question

If one strand of the DNA has the sequence of AGCTTC what will be the other strand be ?

A DNA nucleotide consists of

Small extrachromosoal pieces of DNA found in prokaryotes which replicate independently of the of the chromosome and provide the cell with different traits are

Codons are recognized during

The role of translation is to

Answer 1

Question 1:

Sequence of DNA : AGCTTC

Sequence of other DNA will be: TCGAAG

Adenine always binds with Thymine while Guanine always binds with Cytosine.

Question 2:

A DNA nucleotide is consist of:

1: Nitrogenous base ( Purine or Pyrimidine)

Purine: Adenine and Guanine are purine nitrogenous base

Pyrimidine: Guanine and Cytosine are pyrimidine nitrogenous base.

In RNA, the bases are adenine, thymine, uracil, and cytosine,

2: Pentose sugar:

In DNA the sugar is 2'-deoxyribose.

In RNA, the sugar is ribose

3: Phosphate group: Presence of one or more phosphate group.

Question 3:

Plasmids are small extrachromosoal pieces of DNA, which replicate independently from the host cell chromosome.

Although they are not essential for bacterial growth, they have genes for toxicity and carry genes for drug resistance.

Plasmids may be transferred between cells during recombination processes are are known to multiply independently during cell reproduction.

Question 4:

Codons are recognized during translation.

In eukaryotes AUG closest to the 5' end of an mRNA molecule is usually the start signal for protein synthesis.

Question 5:

Role of translation is to synthesize protein.

Synthesis of protein from an RNA template is termed as translation.

After the recognition of start codon ( AUG), a reading frame is established, groups of three non overlapping nucleotides are defined, beginning with the initiator AUG codon.

UAA, UAG, UGA designate chain termination. These codons are not read by tRNA molecules but rather by a specific proteins called release factors. Binding of the release factors to the ribosomes releases the newly synthesized protein.
