Answer:
1) The statement is false
2) Option A) deoxyribose, phosphate, and a nitrogenous base
Explanation:
1) In semi-conservative DNA replication:
- a parent double-stranded DNA splits in two.
- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate synthesis of a new daughter strand
- the newly synthesized strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, because the parent strand is retained in the newly synthesized DNA, DNA replication is described as semi-conservative
2) DNA consists of several repeating units of polydeoxynucleotides where each is made up of a nitrogenous base (Adenine, thymine, cytosine or guanine) linked to
deoxyribose sugar by an N-glycosidic linkage, and then the sugar linked to a phosphate group by phosphoester bond.
Answer:
Cancer
Explanation:
they start to lose hair and they get sick because of cancer
<span>The third option:</span><span>This statement is true because every step in protein synthesis requires enzymes, which are nothing but proteins.</span><span>
</span>I mean if you look at rRNA which is needed to make polypeptide chains, it is 2/3 protein, and then the helices, ss binding proteins, DNA polymerase and everything in transcription is protein.
So that last option/ third option is the best
Answer:
1. Eukaryotic
2. Eukaryota
Explanation:
1. Eukaryotic- The newly found species has a cell wall and contains membrane-bound organelles. The presence of membrane-bound organelles shows that the cell is a Eukaryotic cell.
2. Eukaryota- the species is single-celled with the presence of cell wall without peptidoglycan. This shows that the species could belong to the Eukaryota domain proposed by Carl Woese.
Thus, 1. Eukaryotic and 2. Eukaryota is the correct answer.
Accuracy would be hitting the target and precision is independent from accuracy because precision is determined by how close 2 or more points are (you can be very precise, but still be inaccurate.)
