The correct answer is: b. the removal of introns and alternative splicing of exons
Post-transcriptional regulation includes processes of regulation between transcription and translation such as RNA splicing, capping, addition of poly-A tail, RNA editing.
RNA splicing represents the process of RNA processing in which newly synthesized pre-mRNA transcript is converted into a mature mRNA. This process occurs only in eukaryotic organism and includes the removal of introns and joining together the exons. RNA splicing might occur during or immediately after transcription and it is performed by spliceosome (complex of small nuclear ribonucleo proteins).
Alternative splicing is a regulated process in which a single gene can code for multiple proteins because particular exons of a gene may be included within or excluded from the final mRNA.
Answer:2 creeper, I normal
Explanation: According to mendelian law when 2 creeper are crossed we should have 3 creeper and 1 normal but because homozgous allele is lethal(lethal means allele that are deleterious and it causes the death of the individual carrying it) it leads it death and we have 2 creeper and 2 normal. The creeper are heterozyous having two different allele.
For everywhere that homozygous individual that are dominant for creeper occur it will always leads to there death because the allele are lethal
One is the diversification
of food sources. Second is increasing agricultural
production by implementing good agricultural practices and adopting
contemporary technologies such as Genetically Modified Foods. The third is increased exports to these counties
with undefined populations. Fourth is embracing good agricultural land management practices such as reducing land
fragmentation/subdivision so as to promote large-scale
production.
Answer:
Climate changes, A loss of habitat
Explanation:
Carbon Dioxide warms the Earth, making more climate change
If the temperatures drop, creatures in cold regions will die <3

After the macrophage fails the Helper T Cell stimulates the B cells if pathogen is extracellular and Cytotoxic T Cells if the pathogen is intracellular. Once the pathogen is killed the B Cells create Memory B Cells and the Killer T Cells create memory T Cells.
