The right answser is Chromosomes.
After DNA replication during cell cycle interphase, the chromosomes are composed of two identical chromatids attached at the centromere. Each chromatide is formed of a molecule of DNA (the nucleofilament) associated with proteins, the histones, around which it winds to form nucleosomes. At the ends of each chromatid are telomeres, consisting of repetitive DNA sequences that provide protection for chromosomal endings. Telomeres and centromere do not encode genetic information, it is non-coding DNA.
Hi Mark
The answer is : D
A hox gene likely affected
I hope that's help:)
Gene mapping describes the methods used to identify the locus of a gene and the distances between genes. The essence of all genome mapping is to place a collection of molecular markers onto their respective positions on the genome. i hope this helps.
They separate during meiosis I is true of tetrads.
Explanation:
In Prophase 1, tetrads are formed. Each chromosome has two sister chromatids. When two homologous chromosomes align for crossing over they have four parts and these are termed tetrads.
When homologous chromosome separate tetrads get broken. Tetrads are not present in mitosis because no crossing over takes place in mitosis.
In Anaphase 1 homologous chromosome separate by getting pulled by spindle fibres forming two haploid cells and tetrads get separate.
Answer:
The Geostrophic wind obeys a number of simple rules. It blows parallel to the isobars. It blows such that if the wind is at your back, the low pressure will be on your left in the northern hemisphere.
Explanation:
