Answer:
An enzyme can be described as a biological molecule which catalyzes a reaction. Each organism works best at an optimum temperature and pH.
If the pH is too high or too low than the optimum pH, then the enzyme such as enolase will become denatured and it will not be able to catalyze the reaction.
A change in pH causes the enzyme the shape of an enzyme to get changed or it changes the specific charge properties of the substrate of that enzyme. As a result, the substrate is no longer able to fit into the active site of the enzyme. Hence, the enzyme is not able to catalyze the reaction.
<h2>Maternal effect</h2>
Explanation:
In maternal effect the phenotype of the progeny is decided by the genotype of the mother
- The female partner is one step ahead to her male partner
- The ovum transcribes some of its nuclear genes prior to fertilization and these genes are responsible for the development of embryo that is why these genes are called maternal effect genes
- This effect is observed in Drosophila
In the given question both male and female have brown eyes with Nn genotype,phenotype of the offspring will be decided by the genotype of mother(Nn) hence despite of having recessive genotype(nn) all the offsprings will show brown eyes
A. Contraction because when you contact a muscle cell, it shortens. When you expand, it gets longer.
Answer:
a.genetic code in the nucleus- DNA
b. main component in a ribosome- rRNA
c. translated with introns removed- mRNA
d. attached to amino acids -tRNA
e. translated including introns- pre-mRNA
Explanation:
a. DNA- is a nucleic acid molecule that acts as a genetic material in the organisms. In eukaryotes, the DNA molecule is present in the nucleus of the cell
.
b. rRNA- is a molecule formed by the transcription but does not undergo translation and is directly involved in the formation of the ribosome structure which provides the site for the protein synthesis.
c. mRNA- is the RNA formed from the DNA by transcription which contains the message for the formation of the protein molecule. The mRNA is formed after the modification like splicing which removes the non-coding sequence.
d. tRNA-transfer RNA is involved in the translation of mRNA as it brings a specific amino acid to the peptide after it recognizes the codon.
e. pre-mRNA- is the mRNA molecule that has not undergone any modification and thus contains the non-coding sequence also.
Answer:
Yes.
Explanation:
Bacteria are the simplest of creatures that are considered alive. Bacteria are everywhere. They are in the bread you eat, the soil that plants grow in, and even inside of you. They are very simple cells that fall under the heading prokaryotic. You don't usually get infected by dead bacteria, because They get recycled. Unlike larger organisms, when single-celled organisms die, they usually undergo a process called lysis, in which the cell membrane disintegrates.
