The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently).

Geologists can 'read' rock layers using relative and absolute dating techniques. ... Relative dating arranges geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy (the rock layers are called strata).

What happens next after the ribosome reaches the start codon?
iris [78.8K]

RNA molecules attach to codons when the ribosome reaches the start codon.

Explanation:

The start codon initiates translation of the mRNA by the ribosome into a polypeptide. When the ribosome finds the start codon, it attaches to the mRNA and the first amino acid, methionine, is recruited. The ribosome then continues translating the rest of the mRNA until it encounters a stop codon that initiates the ‘knocking off of the ribosome from the mRNA.

Describe the genetic mutations that you think occurred in the cancer cells that were responsible for the phenotypic differences
ruslelena [56]

ANSWER:

Most types of cancer are believed to begin with a random genetic mutation. This is followed by mutations, which endow the cancer cells with properties allowing them to grow without normal controls to become a tumor.

Mutation is any change in the DNA sequence of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment.

Genetic Mutations that lead to cancer cell formation can occur in two forms:

1. GROWTH-PROMOTING GENES are commonly mutated in cancer cells, becoming SUPER-ACTIVE and producing cells that are too strongly stimulated by growth receptors.

2. Mutations can INACTIVATE the genes that suppress cell proliferation or those that signal the need for apoptosis. These genes are known as TUMOR SUPPRESSOR GENES.
