Ribosomes provide the scaffolding on which tRNAs interact with mRNA during translation of an mRNA sequence to a chain of amino a
vampirchik [111]

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).

A culture of bacteria enters the exponential growth phase with 4,596 cells per mL. After 15 hours, there are 206,104,972 cells p
tekilochka [14]

Answer:

The Growth rate constant (k) will be = 5.16 \times 10^-03  per minute or 0.308  per hour.

Explanation:

Given,

N₀ = 4596 cells / ml

N = 206104972 cells / ml

t = 15 hours

We know that,

                  n = 3.3 \times log  \frac {b}{B}

Where,

n = no. of generation during the period of exponential growth.

∴    n = 3.3 \times log  \frac {b}{B}

       = 3.3 \times log \frac {206104972} {4596}

       = 3.3 × 44844.42

∴   n  = 15.350

We know that,

                 g = \frac {t} {n}

Where,

g =  generation time    

t = duration of exponential growth

∴    g = \frac {t} {n}                             or                ∴    g = \frac {t} {n}

         =  \frac {15 \times 60} {15.350}                                               = 15 / 15.350

          = 900 / 15.350                           ∴  g  = 0.977 hours

∴      g  = 58.63 minutes

We know that,    

               k = 0.301 / g

Where,   k = specific growth rate

∴    k = 0.301 / g                       or                      ∴   k = 0.301 / g  

           = 0.301 / 58.63                                            = 0.301 / 0.977

∴      k   = 5.16 \times 10^-03  per minutes             ∴  k   = 0.308 per hour
