^incorrect 3 TRNA bases are called an anti-codon
Answer: DNA is unwound.
Explanation:
DNA replication is the process where by two identical DNA copies are produced from a double stranded DNA molecule.
Before DNA will replicates, the double helix length of the DNA to be copied must be unwound, the two strands are separated and the hydrogen bond that link the paired bases are broken. Once the are unwound, they are held apart to expose the new bases so that hydrogen bond can link the nucleotides. The enzyme polymerase then join the new nucleotides into a new DNA strand that is complementary to the template.
<span>Beta thalassemia is a blood disorder that reduces the production of hemoglobin. Hemoglobin is the iron-containing protein in red blood cells that carries oxygen to cells throughout the body.
In people with beta thalassemia, low levels of hemoglobin lead to a lack of oxygen in many parts of the body. Affected individuals also have a shortage of red blood cells (anemia), which can cause pale skin, weakness, fatigue, and more serious complications. People with beta thalassemia are at an increased risk of developing abnormal blood clots.</span>
Eukaryotic cells have nuclear membranes, whereas prokaryotic cells do not. They both have a nuclear body, but the prokaryotic cell does not have an actual nucleus. Both cells have DNA, they just have it constructed differently. Also, eukaryotic cells are larger than prokaryotic cells, not smaller. Hope this helps!
Answer: D. It has a nuclear membrane.
