The question is incomplete as it does not have the options which are:
(a)DNA (b)tRNA (c)rRNA (d)mRNA
Answer:
Option-mRNA
Explanation:
The mRNA is synthesized from the DNA and which is also a type of nucleic acid. When the nucleic acid is extracted from the yeasts and then mixed with the resin beads to which the polynucleotide with thymine base oar is attached.
The mRNA will bind to the resin bead as the mRNA after synthesis undergoes modification and attaches poly A tail to the end of the mRNA at 3' end.
This poly-A tail has adenine which easily binds to the thymine and thus mRNA easily attaches to the resin bead.
Thus, mRNA is correct.
Answer:
Through a circumstance known as "secondary transfer DNA", or "Touch DNA".
Explanation:
Most times when a crime is committed, DNA samples are obtained from surfaces in the scene where the crime was committed. There is a very huge possibility of picking up the DNA of someone who was never at the scene of the crime and this is a result of a condition known as Touch DNA.
Because we touch several objects which can be moved to different locations and touch people who are also always mobile, our DNA cells can find their ways to a crime scene where we had never physically been to. This can lead to false verdicts of guilt.
The term for the type of key that biologists used in separating<span> groups of organisms that are based on couplets is called taxonomic key. This key is very useful in the identification and classification of a </span>specific organism and it usually has an analytical characteristic.<span> </span>
THE TWO MOST COMMON REASON FOR MODIFYING THE LAND IN SOUTH AND SOUTH ASIA IS
(i) first is significantly, the area of lands categorized as under forest/woodland and wetlands declined .At the same time, cultivated area increased .
(ii) another is requirement of additional land due to increase in population.
Explanation:
Between 1880 and 1980, the South and Southeast Asian landscape underwent dramatic modification.The 81% of the lost forest and wetland vegetation appears to have been converted into expanded agricultural land.
Human population in this region more than tripled between 1880 and 1980, producing an enormous demand for additional land for cultivation.
