Answer:
The correct answer is option - B. proteins.
Explanation:
The muscle contraction needs two protein that is essential in contraction. The muscle has motor protein myosin and spherical protein actin that are slide on one other in contraction that helps in muscle to contraction.
In the contraction, these protein filaments help to change in length and shape of the muscles. Thin filaments involve actin and thick filament in is myosin filaments.
Thus, the correct answer is option - b. proteins.
Answer:
Ecology is defined as the scientific study of the complex interactions between organisms, and the environment of the earth. Ecologists study, and examine the features of biotic and abiotic factors of the environment.
Abiotic factors include non-living factors, the physical, and chemical attributes, for example light, water, temperature, and nutrients which helps to influence the abundance, and distribution of organisms.
Biotic factors include living factors, the other organisms which are part of a separate environment, similarly influence the abundance and distribution of life present on Earth.
Answer:
A) AUG GAG GGU
B) N-MET-GLU-GLY-HIS
C) 10 amino acids
D) The stop codon here is UAA, instead of UAG. If a tryptophane residue is added where the stop codon is, the GEN polypeptide would be longer
Explanation:
First we must obtain the the complementary chain or mRNA
A) AUG start codon is complementary to DNA TAC triplet, and GAG is complementary to CTC, and GGU to CCA (running from left to right towards 5'DNA direction (AAGCGGATACCTCCCAGTAGATGCTCCGGGGCTAGTGATTTCGAAC-5)
B) TAC corresponds to Methionine, GAG to Glutamate, GGU to Glycine, and CAU to Histidine
C) UAA is the stop codon, that is complementary where the DNA triplet is ATT. From AUG to UAA, we can have 10 amino acids transcribed
D) If a trp is included where the stop codon is UAA, then the mRNA would be longer with a consequent traduction of a longer GEN polypeptide
The scientists that won the Nobel Prize for publishing the first description of the structure of DNA were Watson & Crick.
The presence of palpable lymph nodes.
Lymph nodes are relatively large in children, and the supperficial ones often are palpable even when the child is healthy.
