99. Changing a codon from GUU to __________ will NOT result in a phenotypic change for the organism.

Biology

Answer:

A) GUC

Explanation:

Some amino acids are encoded by more than one triplet codons. The genetic codes GUU, GUC, GUA, and GUG code for amino acid valine. Since these four genetic codes represent the same amino acid, replacing any one of them with others would not affect the encoded protein.

When a mutation changes the genetic code "GUU" into "GUC", there will not be any change in the encoded amino acid (both code for valine). So, this particular mutation would not cause any change in the respective protein and the genetic trait of the organism.

Several species of warblers can live in the same spruce tree ONLY because they.

Why men should not accuse female children for them<br><br><br><br>​
svet-max [94.6K]

Because they are not in charge of deciding the child's gender, males shouldn't accuse women of failing to deliver a male child for them. Everything is dependent on chromosomal fusion.

What is chromosol fusion?

Every now and then, chromosomes fuse. This fusion occurs as sperm and eggs develop, as pairs of chromosomes fold over each other and swap chunks of DNA. Sometimes two different chromosomes grab onto each other and then fail to separate. Scientists have observed both humans and mammals with fused chromosomes.

Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.
