Answer:b. ​ an mRNA transcript to which multiple ribosomes are attached

Explanation: polysome consist of mRNA complex and two or more ribosome coming together to translate mRNA into a polypetide or amino acid. It helps produce many polypeptide from a single mRNA.

Different ribosomes bind to the mRNA at different time elongating the polypeptide chain. We have the free( non-poly A ) and memberane bound (poly A) polysome.

viktelen [127]

Bacteria that have taken up the plasmid with antibiotic resistance gene will grow in a medium laced with the particular antibiotic of interest. More so, the bacteria that take up plasmid with the lac Z gene, when grown in a medium of lactose only, will propagate. These experiments are used with selective media that only allows the bacteria with a particular characteristic to grow.

dmitriy555 [2]

During the postnatal stage, the various major systems in the body develop at different rates, with the brain reaching full development first, then dentition, then the whole body, and finally the reproductive system. Thus, option "C" is correct.

<h3>What is postnatal stage?</h3>

The postnatal stage-from infancy to childhood to the juvenile period to adolescence to adulthood-involves growth acceleration and deceleration. Childhood and adolescence are long events, in which adult behaviors are learned, individuals become completely mature, and the reproductive capacity develops.

Thus, option "C" is correct.

TEA [102]

<u>Answer:</u>

The codons that signal the end of a polypeptide chain are called the terminators.

<u>Explanation:</u>

The codons that signal the end of a polypeptide chain are called the terminators.

A codon is a series of 3 DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) nucleotides which corresponds to a particular amino acid or just stop the signals which are sent during the protein synthesis.

The terminators are the codons (also called termination codons) which signal the end of the polypeptide chain during the process of translation.
