Answer:

The base adenine pairs with thymine, and the base cytosine pairs with guanine.

Explanation:

From Chargaff's discovery, which was that the DNA of any given species contains equal amounts of adenine and thymine, and equal amounts of cytosine and guanine, we can deduce that if there is an equal amount of two bases in DNA, those two bases must pair together. From this information, we can then go on to say that since there are equal amounts of adenine and thymine, they pair together, and since there are equal amounts of cytosine and guanine, they also pair together.

Answer:

Ribosomes,cytoplasm ,cell wall and circular DNA could be used to justify that the cell is a prokaryote.

Explanation:

Ribosome  Ribosome is present in both prokaryotic cell and eukaryotic cell.The prokaryotic cell 70S ribosome which contain 2 subunits the larger subunit is 50S and the smaller subunit is 30s

Cell wall  Prokaryotes such as bacterial cell contain cell wall.Cell wall  of bacteria contain various carbohydrates which are crosslinked with peptides resulting in the formation of peptidoglycan.

Cytoplasm The cytoplasm of prokaryotic cell such as bacteria contain ribosomes,chromosome and extracellular genetic material called plasmid.

Circular DNA Almost all prokayotic chromosome contain circular DNA molecule that does not contain any free ends.

Write down the tRNA anti-codons that pair with the mRNA strand.
fredd [130]

Answer:

tRNA molecules bring a specific amino acid to the ribosome, according to the mRNA codon.

Explanation:

In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.

What is a gamete?
Talja [164]

Answer:

C. A haploid cell produced by meiosis

Explanation:

The reason being is that meiosis takes diploid cells and splits them in half again giving it half of the organism's DNA so then when it mates it joins the other gamete to give the zygote a complete set of DNA.
