If color blindness is an X-linked recessive trait, what genotype in a father and a mother would be predicted to produce a 1:1 ra
Likurg_2 [28]
The genotype would be X'Y for the father (he would be colorblind)
The genotype would be X'X for the mother (she would be a carrier)
The offspring would be X'X' _ X'X_ X'Y_ XY
The ratio would be 1:1 normal to colorblind
Hope this was helpful(;

The codon AUG specifies the amino acid methionine. What would the tRNA anitcodon be that recognizes this codon?
NemiM [27]

Answer:

UAC

Explanation:

This example portrays that translation, which is the second process of protein synthesis, is about to occur. Translation cannot occur without a special type of RNA called tRNA or transfer RNA.

A tRNA contains a set of three nucleotides called ANTICODON. The tRNA matches an mRNA codon with the amino acid it encodes. The tRNA initially binds to the mRNA and reads the mRNA codon using its anticodon (which is complementary to the mRNA's codon). The actual reading is done by matching the base pairs through hydrogen bonding following the base pairing rule i.e. A-U, G-C. After reading the mRNA codon using its anticodon, it then carries the specific amino acid encoded by that codon it binds to, in order to add to the growing polypeptide chain.

For example, a codon AUG (start codon that signals beginning of translation) will be read by tRNA anticodon, UAC. Since the codon AUG codes for amino acid, Methionine. The tRNA then carries Methionine via its amino acid attachment site and adds to the polypeptide chain (future protein).

What takes place when you inhale?
bezimeni [28]

Explanation:

When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale
