Answer:
I hope you spend that much time, happily at peace.
Answer:
A 22 to 25 amino acid sequence present in the central section of the protein, which gives rise to an alpha helix in the membrane is known as the stop-transfer anchor sequence. The sequence plays an essential function in targeting the protein towards the plasma membrane. On the other hand, it also ceases targeting of the protein towards the endoplasmic reticulum, which was started by the signal peptide.
Thus, the process of translation of the remaining of the protein occurs within the cytosol due to the tethering of the transmembrane domain. In the stop-transfer anchor sequence, the hydrophobic amino acids present are isoleucine and valine. After mutation, these amino acids get converted into arginine and lysine, thus, hydrophilic amino acids replace hydrophobic amino acids in the sequence.
Due to this, the transmembrane domain cannot be targeted towards an integral part of the plasma membrane by the short transfer anchor sequence, and therefore, now the translocation of the protein will take place towards the endoplasmic reticulum as initiated by the signal peptide at the beginning.
It is just s. It is for second.
Answer:
The correct statement is
Option D. Plants use light energy to produce food molecules during photosynthesis and obtain cellular energy from the bonds of these food molecules during cellular respiration.
Explanation:
Photosynthesis is food producing process in which food is produced by plants in the presence of sunlight while respiration is energy releasing process in which energy is released due to the breakdown of glucose molecules.
Answer:
6) 1. Crossing over: crossing over can mean any number of things. It could mean transforming, like making a change, or something as silly as crossing a bridge. In biological terms, it means transforming onto another stage, like a caterpillar making a chrysalis so it can cross over ino the final stage of its life: a beautiflul butterfly.
2. Its during the S phase when the chromosomes are replicated also they significant cell growth occurs.
7) 1. The parent cell in mitosis starts out as a diploid cell and it splits into two haploid daughter cells.
2. diploid spores that undergo meiosis.
8) I don’t know
9) 1. Sex cells have half a set of chromosomes, 23, while parent cells have 46.
Explanation: that all the answer there but for number 8 it look like the same question but uh..., hope this help
