Answer:
a. Bacteria cannot carry out splicing.
Explanation:
Human genes contain non-coding sequences called introns. Transcription of genes produces primary transcripts that undergo post-transcriptional modifications to produce mature mRNA. These modifications include removal of introns, the addition of 3' poly-A tail and 5' cap. The splicing of introns from primary transcripts is followed by ligation of protein-coding sequences exons to produce mature mRNA. The mRNA leaves the nucleus and serves as a template for protein synthesis.
Splicing of introns requires specific machinery such as several small nuclear ribonucleoprotein complexes, etc. which are not present in a prokaryotic cell. Therefore, a eukaryotic gene like the gene for human growth hormone is not expressed in a bacteria cell as these prokaryotic cells cannot carry out the splicing of introns from pre-mRNA.
Answer:
people have unique, genetically influenced reactions to particular experiences
Explanation:
According to the gene-environment interaction, genetic makeup of an individual determines its potential response to particular sets of conditions. Interaction of environment with genes conditions required to bring about those potential responses.
For example, genes of an individual predispose the ability to withstand stressful conditions and the presence of motivating surroundings enables the individuals to achieve their maximum potential.
If the same individuals were brought up under the conditions of deprivation, the resistance level would not have reached its optimum value. Hence, genes determine the limits on abilities and environment determines how much of these abilities are retrieved.
Answer:
down below
Explanation:
The answer is when the waves meet the shore and cause the crest to spill over the trough. This activity creates a back and forth movement of the sand which causes them to settle at a certain area under below the water.
the factors are light intensity, carbon dioxide concentration and temperature. So you know which one is.
Answer:
b.sedimentary rock
Explanation:
because when magma cools it hardens
