what are the materials which change their form and structure over time
Answers
Explanation:
Genes are the material which change their structure with time. Genes undergo mutations, for example, due to environment or any other reason. A mutation can cause a gene to encode a protein that works incorrectly or that doesn't work at all.
Answer:
Genes are a type of substance that undergo structural change over time.
Explanation:
A gene is the basic biological unit that makes up heredity both structurally and functionally. The part of genes that is DNA. The production of proteins is governed by a few specific genes. But a lot of genes don't encode proteins. A human gene might include as few as a few hundred DNA bases or as much as 2 million. The Human Genome Project, a global effort to determine the sequence of the human genome and catalogue its genes, estimates that humans contain between 20,000 and 25,000 genes.
In each person, there are two copies of each gene, one from each parent. A small group of genes varies slightly from person to person, but the bulk of humans share the same genes.
