(a) What are chromosomes made of? (b) Compare and contrast mitosis and meiosis.Cell division:After undergoing prophase, metaphase, anaphase, and telophase, the cell divides into two daughter cells with the chromosomal contents of the parent. The chromosomes are the components that...
What is the structure of DNA and the organization of eukaryotic chromosomes? Which strand of DNA is used to make mRNA? Fill in the blank: Genes that are located close to each other on the same chromosome are referred to as ___ genes. An exon...
The DNA itself consists of compounds known as nucleotides. In the smallest chromosome, in human beings, a molecule of DNA is said to contain about 50 million pairs of nucleotides. For each strand of DNA, the nucleotides are made up of a nitrogenous base/nucleobase (adenine (A), guanine (...
Males have one copy of the X chromosome (inherited from the mother) and one copy of the Y chromosome (inherited from the father). Arranged on the chromosomes are genes. Genes are made of DNA and contain the instructions for building proteins and are integral in making and maintaining the ...
The very long strand of DNA which further contains many genes (hundreds to thousands) makes up a chromosome. The genes are arranged in a particular sequence and have a particular location on the chromosome (called its locus). In addition to DNA, chromosomes also contain man...
A chromosome is just a compact store of DNA. A chromosome is simply a lot of DNA strands folded and compacted together. This compacting is done in a special way. The Chemical bases in the DNA are held in place by The Double Helix. The Double Helix continues to wrap itself around protein...
Genes are a crucial part of our DNA that determine what traits we have. We inherit one set of genes from our mother and one from our father, so we have two copies of each gene. Sometimes we have two of the same alleles, or versions of the gene, and sometimes we have two different...
