Answer:
The correct answer is: translocation.
Explanation:
Translocations are <u>chromosomal abnormalities</u> that are caused by an error that can occur during meiosis <u>when a piece of a chromosome breaks off and it is attached to another chromosome that is not its homologous pair. </u>
There are two types of translocations when taking into account if there were a loss or gain of genetic material, or if it weren't. The type of translocation where there's no loss or gain of genetic material is called balanced, since the information is still there but in a different location.
Answer:
The environment
Explanation:
Because deforestation cause erosion , flooding and desertification which affects the environment
Because we can’t tunnel down, so in order to study the interior layers, we must use indirect methods.
Answer:
a. Cap and tail
b. Codon
c. Promoter region
d. Anticodon
e. Introns
f. Genetic code
g. Exon
Explanation:
a. RNA processing which occurs post transcription, is composed of three steps: capping of 5' end, polyadenylation of 3' tail and RNA splicing. Hence, according to this question, Cap and tail are examples of RNA processing.
b. A codon is a sequence of three nucleotides that code for an amino acid. For example, AUG is a codon that encodes Methionine amino acid.
c. The PROMOTER region is the location on DNA where RNA polymerase enzyme attaches to for transcription to be initiated.
d. ANTICODON is a sequence of three nucleotides located in tRNA that is complementary to a codon triplet. The tRNA anticodon reads the mRNA codon during translation.
e. The INTRON is that portion of a gene that is excised or removed from the RNA transcript. Introns are non-coding regions of a gene and hence needs to be removed during a process called SPLICING.
f. GENETIC CODE is a set of rules that convert a nucleotide sequence into a protein. The genetic code is made up of codons that specify amino acids.
g. EXONS, in contrary to introns, are the parts of a gene that is expressed. Exons are the coding regions of a gene that are expressed into amino acids.
Answer:
Mitosis is a cell division in which, before the true division, DNA replication takes place, temporarily doubling the number of chromatids. This stages that, at the end of the cell division, daughter cells will have the same number of chromosomes as the parent cell
