Answer:

It enters the cytoplasm and moves towards the ribosome

Explanation:

Transcription is the first process of protein synthesis or gene expression. Transcription, which occurs in the nucleus, uses nucleotide sequences of DNA as a template to make an mRNA molecule.

mRNA, which is a complementary strand of DNA sequence, is a conveyer of the genetic instruction stored in the DNA molecule from the nucleus to the site where the genetic code will be read and used to make proteins, a second process of gene expression called translation.

Because the mRNA molecule unlike DNA is not used for long term storage, it exits the nucleus and gets transported into the cytoplasm where it attaches to a complex containing ribosomal proteins and specialized RNA molecules specifically the ribosomal RNA (rRNA) and transfer RNA (tRNA), this complex is known as RIBOSOME. The mRNA molecule in the ribosome is used as a template to assemble the series of amino acids to produce a polypeptide with a specific amino acid sequence.

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).

Each row in the auditorium has 18 seats and 246 and teachers are going to watch an assembly in the auditorium how many rows of s
Romashka-Z-Leto [24]

13

Explanation:

We will divide the total number of the teachers (246) in the auditorium with the maximum number of seats per row (18) to determine how many rows are completely filled;

246/ 18  = 13.6667

We are only interested in rows that are completely filled which is the whole number;

= 13

viktelen [127]
In my opinion, the correct answer among the choices listed is option C. The members of the kingdom Protista are least similar to a bacteria. Protists are eukaryotic organisms which cannot be classified as a fungus, animal, or a plant. They are mostly unicellular organisms.

What molecules are required for the Calvin cycle? (3 answers)
Ber [7]

Answer:After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build food in the form of carbohydrate molecules. The carbohydrate molecules made will have a backbone of carbon atoms. Where does the carbon come from? The carbon atoms used to build carbohydrate molecules comes from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.

Explanation:The Interworkings of the Calvin Cycle

In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle. Others call it the Calvin-Benson cycle to include the name of another scientist involved in its discovery (Figure 5.14).

This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
