During anaphase 1 chromosomes in the homologous pair moves to the opposite poles.
<h3><u>
Explanation:</u></h3>
The chromosomes that are having their pairs with similar length, position of centromere and staining pattern refers to the homologous chromosomes. These chromosomes have genes with the corresponding loci. One of these chromosomes will be inherited from the father and the other will be inherited from the mother.
The chromosomes in the pair gets attached to the fibers from the opposite poles. The chromatids that are sister will get attached to the fiber from the same poles. The centromere will not get divided during the anaphase 1 and thus the homologous chromosomes will move to the opposite poles. This causes the homologous chromosomes to get separated.
Answer:
D) can allow the production of different proteins from a single gene.
Explanation:
Alternative splicing:
Alternate splicing is also known as alternative RNA splicing, or differential splicing. Alternate splicing is a regulated process during gene expression in which multiple proteins are produced from single gene.
Actually eukaryotic genes have both Intron and exon sequences. Exons are the sequences present inside mRNA which convert into amino acids and produces peptides while introns are the sequences which are spliced (cut) from pre mRNA.
Some time introns for some proteins becomes exons for other proteins in this ways one gene can produce multiple proteins.
Answer: The chemical reaction in this example is Called hydrolysis in the presence of Lactase
Here is a word equation for the hydrolysis of lactose:
lactose + water → galactose + glucose
Explanation: The equation is called <hydro> + <lysis) of these terms refer to water and splitting respectively. So hydrolysis means splitting with water. Enzymes pull out a monomer by examining where the monomers are connected, and placing a water molecule in between them, resulting in the breakage of the bond between the monomers. Here are two picture to represent it.
