Answer:
He is either not carrying the gene for RP or the RP gene has mutated.
Explanation:
RP or Retina Pigmentosa is an eye defect inherited by a person from a parent. The disease is degenerative as the individual gradually loses his sight. It normally starts off as night-blindness and could go as bad as a total loss of sight.
The mutation of both the RPGR and RP2 genes which are responsible for the function and structure of light-reception in the eye accounts for most cases of Retina Pigmentosa disease.
Answer:
<u>a) strong joints with restricted movement.</u>
Explanation:
Joints which are closely fitted cannot allow free movement because movement requires space in the joint so the bones can move in this space. So a closely fitted joint allow restricted or no movement at all. Weak joints with restricted movements are called weak because they are not well fitted closely. Strong joints with restricted movement is closely fitted, one of the example is joints of skull.
Answer:
C. DNA ligase adds nucleotides to the lagging strand
Explanation:
DNA replication is the process during cell division in which DNA copies itself. DNA strands unwind with the help of helicase to initiate the process. DNA Polymerase III is responsible for prokaryotic replication and adds nucleotides in 5' to 3' direction. Since both the strands of DNA run in opposite direction their replication is slightly different. The lagging strand is also formed by DNA Polymerase III in discontinuous manner leading to formation of Okazaki fragments. DNA ligase joins these fragments once the replication process is completed.
The best suited group for the mentioned plant is Angiosperms and monocot.
Answer: Option C
<u>Explanation:</u>
As mentioned the seed of the plant has one cotyledon and the specific name for these type of plants whose seeds has one cotyledon is called Monocot, Suppose if the seed of the plant has two seeds, It is called dicot.
Hence we can conclude that the mentioned plant comes under monocot and not dicot. On the other hand, Angiosperms refers to the plants that has flowers with it and gymnosperms usually includes plants without flowers and hence we can classify the plant as Angiosperm and monocot.
