Question

QUESTION 5 Which of the following is false? Select all the false choices. Types of horizontal gene transfer in bacteria include; conjugation, transformation, and transduction Translation takes place on ribosomes in the nucleus. Exposing bacteria to UV radiation can lead to induced mutations. Categories of mutation include point mutation, missense mutation and nonsense mutation. Three nucleotides code for three amino acids which is referred to as a codon.

Answer 1

Q5) The false choices are:

Choices	Explanation
Translation takes place on ribosome in nucleus	No, translation does not occur on the nucleus instead it occurs on the cytoplasm
Three nucleotides codes for 3 amino acids which is reffered to as codon	Three nucleotides codes for one amino acid which is reffered to as codon

Q6) The correct option are:

• Copied discontinously
• New nucleotides are added from 5'-3' direction
• Will have several Okazaki fragments

The statement that : has only one primer is wrong as the lagging strand is discontinuos multiple primer are added.

Q7) The correct option is : B

Explanation: In B we can see that the bacteria is present on the top as well as bottom which implies that they can survive with and without oxygen as oxygen is more in the air above culture medium.

If we observe further we can notice most of the bacteria are concentrated in the top of the tube and few in the bottom. Which means that it can survive better with oxygen as the concentration at top is more

Q8) Low temperature is not a denaturing agent upto a certain extent. As most of the samples are not denatured at low temperatures we are able to preserve these in the freezers/deep freezers.
