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.

Svetllana [295]

Answer:

66.6% of the living progeny would be creepers

Explanation:

The creeper allele is Cr for both parents this means that there is a 50% chance that they will pass the C or r trait to their progeny. In this scenario the deleterious inheritance of rr will be 25% so this will not be factored in this answer. The other progeny is CC 25% and Cr 50% for genotype only

The new calculation for living progeny is this: Of the chances of three living progeny there could be one normal CC and two creepers Cr. This means that 33.3% of the living progeny is normal CC and 66.6% of the living progeny are creepers Cr.

Dolphin fins and shark fins: _________
blsea [12.9K]

Answer:

a. are probably built by different genes.

Explanation:

Although sharks and dolphins are aquatic animals belonging to the vertebrate group, sharks are fish while dolphins are mammals. Sharks belong to the class Chondrichthyes which are fish that have a cartilaginous skeleton. On the other hand, dolphins are mammals (class Mammalia) which are animals mainly characterized by the presence of mammary glands. In consequence, both species are not closely phylogenetically linked, thereby those genes involved in the development of the integumentary system (skin) in both species are expected to be different.
