Answer:
D) splicing together of introns through rna processing
Explanation:
Transcription is the process by which an mRNA molecule is synthesized using a DNA template. However, the initial mRNA transcript is considered pre-mRNA until it undergoes post-transcriptional processing to become matured. The mRNA processing involves three steps viz: capping of 5', polyadenylation and splicing.
The 5' end of the mRNA molecule is capped with a 5' cap in the first mRNA processing stage. This is followed by the addition of a poly(A) tail to the 3' end of the mRNA strand. The last step called Splicing involves removal of introns (non-coding regions of sequence) from the mRNA sequence while the remaining protein-coding regions called EXONS are joined or spliced together.
Hence, option D which says: splicing together of introns through rna processing is not correct because exons are spliced together during splicing step of mRNA processing.
If the width is increased it would be harder to stretch more force will be needed to stretch it
Answer:
The given statement is false.
Explanation:
In ecology, one of the means of measuring diversity is Simpson's Diversity Index. This index is generally used to count the biodiversity of a habitat. The index considers the number of the present species, and at the same time each species' abundance.
Simpson's index denoted by D determines the possibility that two characters selected abruptly from a sample will fit to a similar species or some classification other than species. When the value of D is 0, it signifies infinite diversity, while when the value is 1 it denotes no diversity. Thus, the bigger the value the lower will be the diversity.
