Which statement is TRUE?

Biology
1 answer:
Phantasy [73]3 years ago
6 0

Answer:

A

Explanation:

All living organisms ranging from unicellular prokaryotes to multicellular eukaryotes contain genetic material (DNA). This genetic material is usually found on structures called CHROMOSOMES. Although, the chromosomes are contained in the genome of all living organisms, there are differences.

The genetic material of the bacteria (a typical prokaryote) is a single DNA molecule that makes up its single circular chromosomal material, unlike in eukaryotes that contains double-stranded DNA molecules on linear chromosomes. This single circular chromosome of bacteria is found naked in a region of their cell called NUCLEOID, as they do not possess a membrane-bound nucleus that houses it (a unique characteristics of eukaryotes).

The mitochondrial and Chloroplast DNA mentioned in the other options are all components of eukaryotic cells. Bacteria, as a prokaryote does not contain this organnelles. Hence, they are not single replica.

What kind of sequence or structure would you classify this as
jeka57 [31]

Answer:

The correct answer will be option-A.

Explanation:

Inverted repeats are the sequence of the nucleotide in a nucleic acid which is identical but arranged in the opposite orientation. The inverted repeat may be separated by some sequence or they may lie adjacent to each other. They can be read the same from the backwards or forward direction.

In the given question since four bases when read from the forward direction is same as reading the sequence from the backward direction like CGAC can be read the same both backward and forward.

Thus, option-A is the correct answer.

Alpha particles used in the Gold foil experiments are Helium atoms that__?
Harlamova29_29 [7]

Answer:

2. have no negative particle

Explanation:

Helium atoms contains 2 neutrons and 2 protons (or 2 electrons). Thus, it has a mass number of 4 and atomic number of 2.

Alpha particles are heavy and positively charged, which make them to be deflected in a magnetic or electric charge. So, the helium atoms used as alpha particles for the gold foil experiment must have no negative particle.
