Nuclear maturation encompasses nuclear envelope breakdown, meiotic spindle assembly, and chromosome segregation. Cytoplasmic maturation involves major changes in oocyte protein translation and cytoplasmic organelles and is poorly understood.
In the nematode Caenorhabditis elegans, sperm release the major sperm protein (MSP) hormone to promote oocyte growth and meiotic maturation.
Large translational regulatory ribonucleoprotein (RNP) complexes containing the RNA-binding proteins OMA-1, OMA-2, and LIN-41 regulate meiotic maturation downstream of MSP signaling.
To understand the control of translation during meiotic maturation, we purified LIN-41-containing RNPs and characterized their protein and RNA components. Protein constituents of LIN-41 RNPs include essential RNA-binding proteins, the GLD-2 cytoplasmic poly(A) polymerase, the CCR4-NOT deadenylase complex, and translation initiation factors.
RNA sequencing defined mRNAs associated with both LIN-41 and OMA-1, as well as sets of mRNAs associated with either LIN-41 or OMA-1. Genetic and genomic evidence suggests that GLD-2, which is a component of LIN-41 RNPs, stimulates the efficient translation of many LIN-41-associated transcripts.

Answer:
The answer to the question is d
The appropriate options of the given question is as follows:
a. The high specific heat capacity of water allows the body to absorb a large amount of excess heat energy.
b
. The high heat of vaporization of water allows the body to remove excess heat through a phase change of water from liquid to gas.
c
. The high surface tension of water contributes to the physical process by which water leaves the body.
d
. The high melting temperature of the water allows the body to remove excess heat through a phase change of water from solid to liquid.
Answer:
The correct answer is - Option a. and b.
Explanation:
Sweating is one of the processes of the homeostasis that helps in the regulation of the body temperature in humans and other animals. Sweat helps in preventing the body from overheating if the external environment is high in temperature. The sweat evaporates to release heat in form of calories which helps in the regulation of body temperature.
Due to the high heat capacity of water, helps to more evenly distribute or transfer heat in the body. It helps in maintaining a more even temperature by transporting heat from warm places to cool places.
Thus, the correct answer is - a and b.
Answer:
The correct answer is - Methionine, serine, histidine, aspartate, glycine
Explanation:
The new segment of DNA is: 3'-TACAGGGTGCTACCCACT-5', which performs two processes to form a peptide chain, transcription, and translation. In transcription, the DNA segment is encoded to an mRNA molecule which has its complementary sequence to DNA sequence.
New DNA strand: 3'-TACAGGGTGCTACCCACT-5'
mRNA sequence: 3'-AUGUCCCACGAUGGGUGA-5'
The translation of this mRNA would be on the basis of chart
AUG - Methionine (start codon)
UCC - serine
CAC - histidine
GAU - aspartate
GGG - glycine
UGA - stop codon
The peptide chain would be - Methionine, serine, histidine, aspartate, glycine
