whcih structure carroies genetic information
The genetic information is carried in the structure called DNA (Deoxyribonucleic acid). DNA is a double-helical molecule composed of nucleotides which contain the genetic code.
which option contains all of the other ones listed
chromosone
gene
centromere
chromatid
A chromosome contains all of the other structures listed: gene, centromere, and chromatid.
are you sure thats right
My apologies for the error in my previous response.
To clarify:
- A chromosome is a structure composed of DNA and proteins that carry genetic information.
- A gene is a specific sequence of DNA that contains instructions for the formation of a functional product, such as a protein.
- A centromere is a region on a chromosome that holds together sister chromatids during cell division.
- A chromatid refers to one of the two identical copies of a duplicated chromosome that are joined at the centromere.
So, to answer your question accurately, a chromosome contains two chromatids, each of which contains genes and a centromere.
