Answer:
a. True
Explanation:
Ribosomes are ribonucleoprotein complexes composed of RNA and proteins, which have two main roles 1-decode the message of the messenger RNA (mRNA) molecule and the formation of peptide bonds in the protein. For this purpose, each triplet of nucleotide bases or 'codon' in the mRNA sequence is used to assemble specific amino acids in the nascent polypeptide chain. Although different, both prokaryotic ribosomes and eukaryotic ribosomes are composed of two subunits: one small subunit that decodes the mRNA into a specific amino acid chain, and one large subunit that forms the peptide bonds in the polypeptide chain. Each ribosomal subunit is in turn composed of ribosomal RNAs and proteins. These ribosomal RNAs act as scaffolds by combining with proteins that assemble into ribosomes (i.e., small and large ribosome subunits).
According to the Doppler effect, the sound of a police car siren is louder and high pitched as it approaches the observer.
Nervous tissue is made up of neurons and supportive cells. Throughout the human body the neurons carry electrical and chemical signals, while nutrition is provided by the supportive cells.
Answer:
The correct answer is - CNN.
Explanation:
Protein modification or folding takes place in the endoplasmic reticulum. The Endoplasmic Reticulum modifies the amino acids according to their signal sequences and tail. The following case can help in indicating the C-terminus (C) or the N-terminus (N) of each of the following proteins-
A) the C-terminus would be placed in the cytosol and the N-terminus in the endoplasmic reticulum lumen after cleaving the N-terminal signal sequence.
B) The N -terminal is the positive end of the chain and as per the rule of positive inside it allows N terminal in the cytosol
( C ) Tail-anchored proteins always have their N-terminal bulk in the cytosol.
Thus, CNN would be the correct answer from the explanation given above.
