<h2>. A human diploid cell has 46 chromosomes in 23 pairs.</h2>
Answer:
Gene knockout is a technique used to determine the function of a gene that has already been sequenced, which is achieved by analyzing the phenotype of the individual carrying the knockout mutation(s). Moreover, gene sequencing is a technique used to determine the sequence of a given gene, which allows to determine how gene variants (polymorphisms) may be associated with the phenotypes of the target trait.
Explanation:
In genetics, gene knockout is a technique used to trigger mutations in a (already) sequenced gene in order to inactive its function and observe the resulting phenotype for a particular trait. This approach that starts with the inactivation of a given gene and ends with the phenotype is known as reverse-genetics. On the other hand, gene sequencing can be defined as the methodologies/techniques/tools used to determine the nucleotide base pair sequence of a particular gene. The gene knockout technique involves knowing a priori the gene sequence in order to obtain a gene knockout (gene KO). The combination of the information obtained from these techniques can be used to determine how variation (genetic variation) affects the expression of a phenotypic trait.
Answer:
The protein would be incorrect and the protein might not function.
Explanation:
We know that introns carry information but introns not only carry information to build a protein. They have to be removed for the mRNA to encode a protein with the right protein sequence.
If the spliceosome fails to remove an intron, an mRNA with extra "junk" will be created in it. As a result, a wrong protein will be created during translation.
If a wrong protein sequence is created, it will hamper the whole translation process. The protein won't function properly.
The answer is B. Primase produces RNA, making it a type of RNA polymerase. RNA is complimentary to a single strand of DNA.
Answer:
True
Explanation:
The stratosphere is the layer of the earth’s atmosphere which is above the troposphere and below the mesosphere.
The stratosphere contains about 90 percent of the ozone layer. The stratosphere is made up of ozone layers which helps in the absorption of about 95 percent of the ultraviolet rays from the sun and converting to heat.
This is the reason why depletion of the ozone layer found in the stratosphere gives rise to global warming.
