Answer:

When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents. They are present in the egg and/ or sperm cells.

What type of mutation can affect offspring?

The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. No change occurs in phenotype. Some mutations don't have any noticeable effect on the phenotype of an organism.

Explanation:

Genetic alternations include chromosomal abnormalities and gene mutations. Chromosomal abnormalities generally arise during cell division. ... Gene mutations are permanent changes in DNA gene sequence. They can arise during normal DNA replication or in response to environmental factors.

Answer:

Apples : adenine

Trees : thymine

Cars : cytosine

Garages : guanine

Explanation:

The bases in DNA are adenine, thymine, guanine, and cytosine. It helps to remember the popular mnemonic, "apples in the tree," that helps you remember that A goes with T, and "car in the garage," so C goes with G, to understand how DNA bases pair. The bases in RNA are adenine, uracil, guanine, and cytosine.

Which statement does not describe an organism that reproduces asexually?

antoniya [11.8K]

Answer: Male and female gametes are involved.

Explanation: Asexual reproduction is a type of reproduction in which one or more offspring is produced from a portion of a single parent without the involvement of the gametes or sex cells. It promotes rapid multiplication in many organisms and reduces the chances of introducing more variations into a population. Types of asexual reproduction include budding, fragmentation, spore formation and fission.

Reading from 5’ to 3’, this RNA product has the sequence ____________ . It binds to the small subunit of the ____________ . It i

Tamiku [17]

Answer:

AUG, ribosome, initiation, translation

Explanation:

The transfer of information from DNA to RNA to protein is called Central Dogma. The formation of protein from mRNA is translation. The translation begins with initiator codon AUG in mRNA. The ribosome small subunit (30s) binds to the RNA. The tRNA binds and then large subunit (50s) attaches with mRNA.

Thus, reading from 5’ to 3’, this RNA product has the sequence AUG. It binds to the small subunit of the ribosome. It is joined by the large subunit, completing the initiation stage of the process of translation.
